Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a music game, and more particularly to a game device and a program for reproducing music by performing pronunciation according to a player's operation.
[0002]
[Prior art]
A music game is known in which a player plays music by operating an input button or the like according to the timing indicated by the movement or position of an object displayed on the game screen. The music game is a game for competing for the accuracy of input by a player for playing a part of the music. That is, if the player operates the input button or the like at the correct timing, the musical sound is output at the correct timing and the music is played correctly. It is also possible to determine whether or not the stage in the game can be cleared based on the number of operations performed at the correct timing, or to perform a battle-type play among a plurality of players.
[0003]
In such a music game, the game device automatically reproduces the backtrack sound constituting the background sound of the music piece by reproducing the backtrack sound data stored in the DVD-ROM or the like. In addition, the game device reproduces the music sound data based on the input by the player, thereby generating a player input sound corresponding to the sound of the musical instrument constituting the music. Since the player can sound the player input sound based on the input operation of the player, the player can obtain a feeling of playing a part of the music in a pseudo manner.
[0004]
In such a music game, it is necessary to adjust the difficulty level in order to flexibly respond to the player's ability. As an example of a method for adjusting the difficulty level, there is a method for increasing or decreasing the number of inputs by the player. For example, when the difficulty level is set high, an input error by the player is induced by increasing the number of inputs. On the other hand, in the case where the difficulty level is set to be low, an input error by the player is prevented by reducing the number of inputs.
[0005]
The part where the number of inputs is reduced to adjust the difficulty level is not input by the player, so if it is silent as it is, a part of the predetermined song will not be played, and the overall music will be uncomfortable Occurs. Therefore, the portion where the number of inputs is reduced is automatically pronounced by the game device as if it were a backtrack sound of a predetermined music piece.
[0006]
In this specification, of the music sound data, the sound data reproduced based on the input by the player is referred to as “player input sound data”, and “sound data other than the player input sound data is referred to as“ pseudo backtrack sound data ”. " By reproducing the player input sound data, a player input sound is generated, and by reproducing the pseudo backtrack sound data, a pseudo backtrack sound is generated.
[0007]
[Problems to be solved by the invention]
However, conventionally, there has been a problem that it is difficult to distinguish the pseudo-backtrack sound that is automatically generated by the game device and the player input sound that is generated based on the player's input in terms of hearing. Therefore, when the player inputs, it is difficult to distinguish whether the player input sound is pronounced based on his / her input or whether the game apparatus automatically sounds the pseudo backtrack sound. Therefore, the operational feeling of the player in the music game has been impaired.
[0008]
In order to solve the above-described problem, it is possible to easily distinguish the pseudo backtrack sound from the player input sound by a method such as replacement with another tone color. However, the method of replacing with another timbre requires a large amount of memory capacity and increases the load on the game device. Further, from the viewpoint of the player playing a part of a predetermined piece of music in a pseudo manner, new problems such as difficulty in maintaining the musical sound of the whole piece of music occur.
[0009]
The present invention has been made in view of the above points, and distinguishes the pseudo backtrack sound from the player input sound in terms of audibility while maintaining the musical reverberation of the entire music to be played back, so that the player can operate it by himself. Provided are a game device and a program capable of enhancing a feeling of performing.
[0010]
[Means for Solving the Problems]
In one aspect of the present invention, a game apparatus that outputs music by reproducing a plurality of sound data prepared in advance based on player input, wherein the sound data includes a backtrack sound that constitutes a background sound. Data and music sound data corresponding to a predetermined musical instrument constituting the music, and the music sound data includes player input sound data reproduced in response to player input and music other than the player input sound data.

In addition, the game device stores volume change rate information in which the type of musical instrument corresponding to the music sound data is associated with the change rate of the playback sound volume of the music sound data.
[0012]
The game apparatus first determines the type of the corresponding instrument based on the input by the player and the player input sound data or the pseudo backtrack sound data. Then, the game device determines and reproduces the reproduction volume change rate of either the player input sound data or the pseudo backtrack sound data based on the determined instrument type and volume change rate information.
[0013]
According to this, since the player input sound data can increase the playback volume compared to the pseudo backtrack sound data, the player can determine whether or not the playback is based on his / her input without confusing both. It can be easily recognized. That is, even when playback is performed using both player input sound data and pseudo backtrack sound data, the player can enjoy a music game without detracting from the sense that he / she is playing a musical instrument. Also, since the volume change rate is set based on the type of instrument, the player input sound data reproduction and pseudo backtrack sound data reproduction are distinguished from each other without giving a sense of incongruity as the performance of the entire music. It becomes possible.
[0014]
In one aspect of the above game device, the volume change rate information storage means is configured such that, for each type of musical instrument, an instrument with a short pronunciation time has a large volume change rate, and an instrument with a long pronunciation time has a small volume change rate. The volume change rate information is stored as follows. Usually, the volume difference perceived in the sense of hearing varies depending on the type of musical instrument. For example, when a musical instrument with a short sounding time such as a percussion instrument is compared with a musical instrument with a long sounding time such as a wind instrument, even if the sound volume is changed to the same level, the wind instrument is more likely to feel a difference in sound volume. That is, the wind instrument feels as if the volume has been changed more than the percussion instrument. According to the game device configured as described above, the volume change rate is set for each musical instrument in consideration of the volume difference in the audibility depending on the type of musical instrument, so that there is no sense of incongruity in the performance of the entire song.

[0048]
[Music game]
Next, an example in which the present invention is applied to a music game will be described. In the music game, the player operates the controller 12 and inputs a predetermined input in accordance with the timing notified by the moving object (hereinafter referred to as “Pop-kun”) that moves in the play area. It is a game that performs.
[0049]
The music is composed of a backtrack sound that the game device automatically generates as a background sound of the music and a music sound that is generated based on an input by the player. Further, although the music sound will be described in detail later, the music sound is assigned to either a player input sound that the game apparatus generates based on the player's input or a pseudo backtrack sound that is automatically generated by adjusting the difficulty level.
[0050]
Note that the game device has a plurality of sound sources corresponding to the processing capability of the game device, but in advance, the number of sound sources for sounding the backtrack sound and the player input sound or the pseudo backtrack sound are sounded. It is assumed that the number of sound sources is assigned with an arbitrary setting.
[0051]
In the present invention, “sound data” refers to data corresponding to a predetermined sound. That is, when the game device reproduces “sound data”, “sound” corresponding to the sound data is pronounced. From this, the game device stores the backtrack sound data and the music sound data in the DVD-ROM 15 shown in FIG. 1 in order to generate the backtrack sound and the music sound. Further, when the game apparatus reads the backtrack sound data and the music sound data from the DVD-ROM 15 and stores them in the RAM 3, the game apparatus assigns and stores the music sound data to either the player input sound data or the pseudo backtrack sound data. ing.
[0052]
Specifically, a music game will be described with reference to FIG. FIG. 4 is an example of a display screen of a music game. As shown in FIG. 4A, the play area 30 is composed of nine lines, and Pop-kun 31 is generated from the upper part of the screen in each line according to a predetermined music piece. Pop-kun 31 moves along the respective lines from the upper part to the lower part of the screen, and disappears when the player operates the controller 12 and makes a predetermined input when reaching the determination line 32. That is, the timing at which Pop-kun 31 crosses the judgment line 32 indicates the input timing by the player. At this time, if the player makes a predetermined input in a timely manner, an appropriate sound that matches the backtrack sound of the music is generated as the player input sound. That is, the player plays a part of the music piece in a pseudo manner by generating an appropriate player input sound in accordance with the notification timing of the pops 31 generated one after another.
[0053]
Note that Pop 31 is controlled by the game apparatus, and the notification timing is performed based on the timing data read from the DVD-ROM 15 and stored in the RAM 3. The timing data corresponds to the musical score of the music and is data that governs the timing input by the player. That is, the game device generates the player input sound by reproducing the player input sound data based on the player input and timing data.
[0054]
One confirmation button 33 is associated with each line in the play area 30. Further, the confirmation button 33 is associated with each push button switch of the dedicated controller 12B shown in FIG. In other words, the player performs input by pressing the push button switch associated with the line of the dedicated controller 12B in accordance with the timing notified by Pop 31 who moves along the predetermined line. In this way, Pop-kun 31 notifies the player of the input timing based on the timing data.
[0055]
Specifically, as shown in FIG. 4A, it is assumed that the line in the first column from the right in the play area 30 is associated with the confirmation button 33 displayed as “I”. When the player reaches the judgment line 32 along the first line from the right, the player performs input by pressing the push button switch PB12 of the dedicated controller 12B in a timely manner and generates an appropriate player input sound. can do.
[0056]
Next, adjustment of the difficulty level in the music game will be described. In music games, it is necessary to adjust the difficulty level in order to respond flexibly to the player's ability. As an example of a method for adjusting the difficulty level, a method for increasing or decreasing the number of inputs by the player will be described. For example, if the number of inputs is increased, an input error by the player can be induced and the difficulty level can be increased. On the other hand, if the number of inputs is reduced, input errors by the player can be prevented and the difficulty level can be lowered.
[0057]
FIG. 4A is an example of a display screen in the case of a setting with the highest degree of difficulty, and FIG. 4B is an example of a display screen in the case of a setting with a slightly low degree of difficulty. On the display screen shown in FIG. 4A, the player inputs in accordance with the timing notified by the nine pops 31 existing in the play area 30. On the other hand, on the display screen shown in FIG. 4B, the player performs input in accordance with the timing notified by the six pops 31 existing in the play area 30. That is, FIG. 4B has three fewer pops 31 than FIG. 4A, and accordingly, the number of inputs by the player is reduced and the difficulty level is low.
[0058]
Such difficulty adjustment is performed by assigning the music sound data stored in the DVD-ROM 15 to either the player input sound data or the pseudo backtrack sound data. Specifically, in the case of the setting with the highest difficulty as shown in FIG. 4A, all the music sound data is assigned to the player input sound data. On the other hand, in the case of a setting with a low difficulty level as shown in FIG. 4B, the music sound data is assigned so that the ratio of “player input sound data to pseudo backtrack sound data” is “2: 1”. Specifically, as shown in FIG. 4B, the music sound data is allocated so as to have a ratio of the pseudo backtrack sound data “3 lines” to the player input sound data “6 lines”.
[0059]
The game device generates a player input sound based on the input by the player at the timing notified by Pop-kun 31 and the player input sound data. However, since the pop 34 shown by the broken line in FIG. 4B does not actually exist, the input by the player is not performed at the timing that the pop 34 originally notifies based on the timing data. Therefore, the player input sound is not pronounced and becomes silent, and the music is not established. Therefore, the game device assigns music sound data other than player input sound data to the pseudo backtrack sound data. Thus, the game device reproduces the pseudo backtrack sound by reproducing the pseudo backtrack sound data as if part of the backtrack sound instead of the input by the player, thereby establishing the music.
[0060]
As described above, the more player input sound data is assigned to the music sound data, and the less the pseudo backtrack sound data is assigned, the more the number of inputs by the player and the higher the difficulty. On the other hand, as the player input sound data is less allocated to the music sound data and the pseudo backtrack sound data is allocated more, the number of inputs by the player decreases and the difficulty level becomes lower. That is, the increase / decrease in the number of inputs by the player for adjusting the difficulty level is adjusted by assignment to the music sound data.
[0061]
Next, some aspects of the music sound distinction process for distinguishing the player input sound and the pseudo backtrack sound will be described as first to fifth examples of the music sound distinction process.
[0062]
In the first embodiment of the music sound distinction processing, the player input sound and the pseudo back are changed by changing the volume of the pseudo backtrack sound in consideration of the audible volume difference depending on the type of instrument that is pronounced as the pseudo backtrack sound. Distinguish track sounds.
[0063]
In the second embodiment of the music sound distinction process, the player input sound and the pseudo backtrack sound are distinguished by changing the volume of the player input sound in consideration of the time included as a parameter of the player input sound data.
[0064]
In the third embodiment of the music sound distinction process, only the original sound data included in the player input sound data is reproduced and the reverberation sound data is not reproduced, so that the player input sound and the pseudo backtrack sound are distinguished from each other for the sake of hearing.
[0065]
In the fourth embodiment of the music sound distinction process, the player input sound and the pseudo backtrack sound are distinguished from each other for audibility by changing the phase of the player input sound data.
[0066]
In the fifth embodiment of the music sound distinction process, the player input sound and the pseudo backtrack sound are distinguished from each other in terms of audibility by changing the frequency band of the player input sound based on the frequency band of the backtrack sound.
[0067]
[First embodiment]
First, a first embodiment of music sound distinction processing will be described with reference to FIGS. The first embodiment distinguishes the player input sound from the pseudo backtrack sound by changing the volume of the pseudo backtrack sound in consideration of the audible volume difference depending on the type of instrument that is pronounced as the pseudo backtrack sound. .
[0068]
Normally, the volume difference that humans feel in terms of hearing varies depending on the type of musical instrument. For example, when a musical instrument with a short sounding time, such as a percussion instrument, is compared with a musical instrument with a long sounding time, such as a wind instrument, even if the sound volume is changed to the same extent, the wind instrument tends to feel a volume difference in terms of hearing. That is, the wind instrument feels as if the volume has been changed more than the percussion instrument. If the volume reduction rate is set for each instrument, taking into account the difference in the volume of the audibility depending on the type of instrument, the music is less than when a constant volume reduction rate is set regardless of the instrument type. The player input sound and the pseudo backtrack sound can be distinguished without giving a sense of incongruity to the overall performance.
[0069]
FIG. 5 shows an example of setting the volume reduction rate information. The volume reduction rate information is information indicating the volume reduction rate for each musical instrument, and is stored in the DVD-ROM 15. Specifically, the volume reduction rate information shown in FIG. 5 is set such that the volume reduction rate of “drum” is “1.65” and the volume reduction rate of “trumpet” is “1.20”. This is because, even if the volume is changed to the same level, a wind instrument such as a trumpet feels as if the volume is changed greatly in terms of hearing than a percussion instrument such as a drum. Therefore, the volume reduction rate of “trumpet” is set lower than the volume reduction rate of “drum”.
[0070]
Next, functions of the game device in this embodiment will be described. FIG. 6 is a functional block diagram of the game device of the present invention, and shows all functional blocks related to the first to fifth embodiments of the music sound distinction process for convenience of explanation. In FIG. 6, the game apparatus according to the first embodiment of the music sound distinction process includes a backtrack sound reproduction means 50, a pseudo backtrack sound reproduction means 51, a player input sound reproduction means 52, a music sound change means 53, and volume change rate information. Storage means 54 and volume change rate determination means 55 are provided. The DVD-ROM 15 stores backtrack sound data 61, music sound data 62, timing data 63, and a music sound distinction processing program 64. Each function shown in FIG. 6 is realized when the CPU 1 or the GPU 4 shown in FIG. 1 executes the music sound distinction processing program 64.
[0071]
The backtrack sound data 61 is data for generating a backtrack sound that is a background sound of the game. The music sound data 62 is data for generating a sound based on the input of the player in principle. The music sound data is stored in the RAM 3 of the game device as player input sound data 71 or pseudo backtrack sound data 72 based on the difficulty level of the music. Here, the player input sound data 71 is data for generating a player input sound based on the player's input in principle. On the other hand, the pseudo backtrack sound data 72 is data for generating a pseudo backtrack sound that is automatically generated by the game device regardless of the input of the player, in order to adjust the difficulty level. The timing data 63 is data that governs the timing input by the player.
[0072]
The backtrack sound reproduction means 50 reproduces the backtrack sound data 61 to generate the backtrack sound from the speakers 10a and 10b.
[0073]
The pseudo backtrack sound reproduction means 51 reproduces the pseudo backtrack sound from the speakers 10a and 10b by reproducing the pseudo backtrack sound data 72 assigned based on the difficulty level of the music.
[0074]
The player input sound reproduction means 52 reproduces the player input sound data 71 assigned according to the difficulty level of the music on the basis of the player input and timing data 63 in accordance with the timing notified by Pop-kun 31, thereby providing the player input. Sound is generated from the speakers 10a and 10b.
[0075]
The music sound changing unit 53 changes the volume of the player input sound or the pseudo backtrack sound based on the volume change rate information storage unit 54 and the volume change rate determining unit 55 described later.
[0076]
The volume change rate information storage means 54 stores volume change rate information in which the type of musical instrument is associated with the volume change rate of the player input sound or the pseudo backtrack sound.
[0077]
The volume change rate determination means 55 determines the volume change rate based on the type of musical instrument corresponding to the player input sound data or the pseudo backtrack sound and the volume change rate information stored in the volume change rate information storage means 54.
[0078]
Next, a first embodiment of the music sound distinction process will be described with reference to the flowchart of FIG. The processing described below is executed by the CPU 1 based on programs and data stored in the DVD-ROM 15 shown in FIG.
[0079]
In FIG. 7, the game device first determines allocation of player input sound data or pseudo backtrack sound data to music sound data based on the difficulty level of the music as described above (step S1). Then, the game device reads backtrack sound data and music sound data from the DVD-ROM 15 and stores them in the RAM 3. At this time, the game device stores each piece of music sound data in the RAM 3 as either player input sound data or pseudo backtrack sound data (step S2).
[0080]
Next, the game device generates a backtrack sound by reproducing the backtrack sound data stored in the RAM 3 (step S3). Then, the game device determines the type of musical instrument that is pronounced as the pseudo backtrack sound based on the pseudo backtrack sound data stored in the RAM 3 (step S4). Note that the type of musical instrument that is pronounced as pseudo backtrack sound, that is, music sound, can be included in the music sound data as attribute information. Further, the game device determines the volume reduction rate of the pseudo backtrack sound based on the determined instrument type and the volume reduction rate information shown in FIG. 5 (step S5). For example, when the instrument type is “drum”, the volume reduction rate is determined to be “1.65”.
[0081]
Next, the game device reduces the volume of the pseudo backtrack sound based on the determined volume reduction rate. Note that the volume of the player input sound is not changed. Then, the game device generates the pseudo backtrack sound by reproducing the pseudo backtrack sound data with the volume reduced based on the volume reduction rate (step S6). Further, the game device generates a player input sound by reproducing the player input sound data based on the player input based on the timing notified by Pop-kun 31 and the timing data stored in the RAM 3 (step S7).
[0082]
Next, the game device determines whether or not the music has ended (step S8). Here, the music is a music that is played in a pseudo manner by the player making a predetermined input, and the end of the music is determined based on the timing data corresponding to the musical score. If the music has not ended, the game device returns to step S3 and repeats the processing of steps S3 to S8. On the other hand, when the music ends, the game device ends the music sound distinction process.
[0083]
According to this, since the player input sound is pronounced larger than the pseudo backtrack sound, the player can easily recognize the pronunciation by his / her input. In other words, by adjusting the difficulty level, even if there is a pronunciation by both the player input sound and the pseudo backtrack sound, the player can distinguish the sound produced by his operation from the automatic pronunciation by the game device. Can enjoy music games without losing the sense of playing music.
[0084]
In addition, since the volume reduction rate is set based on the type of instrument that is pronounced as the pseudo backtrack sound, the player input sound and the pseudo backtrack sound are not affected by the sense of audibility of the entire music performance. A distinction can be made.
[0085]
In the first embodiment, the volume reduction rate of the pseudo backtrack sound is set for each musical instrument in consideration of the volume difference in audibility depending on the type of instrument, and the pseudo backtrack sound is set based on the volume reduction rate. This makes it possible to distinguish between player input sound and pseudo backtrack sound. However, the present invention is not limited to this, and the volume increase rate of the player input sound is set for each instrument in consideration of the volume difference in the audibility depending on the type of the instrument, and based on the volume increase rate. Player input sound can be increased. At this time, if the volume of the pseudo backtrack sound is not changed, the player input sound and the pseudo backtrack sound can be distinguished.
[0086]
[Second Embodiment]
Next, a second embodiment of the music sound distinction process will be described with reference to FIGS. 6 and 8 to 10. In the second embodiment, the player input sound and the pseudo backtrack sound are distinguished by changing the volume of the player input sound in consideration of the time included as a parameter of the player input sound data.
[0087]
In order to enhance the feeling that the player is playing in the music game, it is necessary to distinguish the player input sound from the pseudo backtrack sound. However, if the volume of the entire player input sound is simply increased as a method of distinguishing the two sounds, the sound may be distorted and the degree of completeness of the entire music may be reduced. Therefore, it is possible to distinguish between the player input sound and the pseudo backtrack sound without giving a sense of incongruity to the entire music piece by changing the volume of the player input sound in consideration of temporal changes.
[0088]
FIG. 8 shows a basic envelope in which the temporal changes in the volume of the player input sound and the pseudo backtrack sound are graphed. The envelope includes four parameters: an attack time, a decay time, a sustain level, and a release time. The attack time is the time from when the sound of the player input sound is started until the volume reaches the maximum value. The decay time is the time for the player input sound to decay to the sustain level after reaching the maximum value. The sustain level is a volume level that continues during the sound of the player input sound. Release time is the time from the end of pronunciation until the player input sound disappears completely.
[0089]
In FIG. 9A, a solid line represents an envelope in which the temporal change of the volume of the player input sound when the attack time is short is graphed. The dotted line is the basic envelope shown in FIG. In this case, the game apparatus increases the volume of the player input sound so that the attack time is shorter than the basic envelope. That is, the volume of the player input sound is increased so that the volume reaches the maximum value earlier than the basic envelope. Note that the temporal change in volume of the pseudo backtrack sound follows the basic envelope.
[0090]
According to this, since the player input sound has a timing when the volume reaches the maximum value earlier than the pseudo backtrack sound, the audibility is improved and the player can easily recognize the sound. However, since the volume of the entire player input sound is not changed, the game apparatus can distinguish between the player input sound and the pseudo backtrack sound without giving a sense of incongruity to the entire music.
[0091]
FIG. 9B shows a solid line with an envelope that graphs the temporal change in the volume of the player input sound when the maximum value of the volume is emphasized. The dotted line is the basic envelope shown in FIG. In this case, the game apparatus increases the volume of the player input sound so that the maximum volume is larger than the basic envelope. Note that the temporal change in volume of the pseudo backtrack sound follows the basic envelope.
[0092]
According to this, since the player input sound has a maximum volume value compared to the pseudo backtrack sound, the player input sound is emphasized and heard. However, since the volume of the entire player input sound is not changed, the game device can distinguish and pronounce the player input sound and the pseudo backtrack sound without giving the entire music a sense of incongruity.
[0093]
In the above example, the volume of the player input sound is changed by using an envelope as shown in FIG. 9A or 9B. However, the present invention is not limited to this, and various methods can be applied as long as the volume changes in consideration of time, such as lowering the sustain level or increasing the release time.
[0094]
Next, functions of the game device in the second embodiment of the music sound distinction process will be described. FIG. 6 shows a functional block diagram of the game device in the present embodiment. In FIG. 6, the game apparatus according to the second embodiment includes a backtrack sound reproducing means 50, a pseudo backtrack sound reproducing means 51, a player input sound reproducing means 52, and a player input sound changing means 53. The DVD-ROM 15 stores backtrack sound data 61, music sound data 62, timing data 63, and a music sound distinction processing program 64. Each function shown in FIG. 6 is realized when the CPU 1 or the GPU 4 shown in FIG. 1 executes the music sound distinction processing program 64. In addition, description is abbreviate | omitted for convenience about the part which overlaps with the structure of 1st Example of a music sound distinction process.
[0095]
The player input sound changing means 53 changes the volume of the player input sound based on the time that is a parameter of the player input sound data 71.
[0096]
Next, a second embodiment of the music sound distinction process will be described with reference to the flowchart of FIG. The processing described below is executed by the CPU 1 based on programs and data stored in the DVD-ROM 15 shown in FIG.
[0097]
In FIG. 10, the game device first determines allocation of player input sound data or pseudo backtrack sound data to music sound data based on the difficulty level of the music (step S11). The game device reads backtrack sound data and music sound data from the DVD-ROM 15 and stores them in the RAM 3. At this time, the game device stores the music sound data in the RAM 3 as the assigned player input sound data or pseudo backtrack sound data (step S12).
[0098]
Next, the game device generates a backtrack sound by reproducing the backtrack sound data stored in the RAM 3 (step S13). Furthermore, the game apparatus determines an envelope that graphs the temporal change in the volume of the player input sound. That is, the change in the volume of the player input sound considering the time is determined (step S14). For example, when an envelope with a short attack time shown in FIG. 9A is used, the temporal change in the volume of the player input sound is determined according to the solid envelope shown in FIG. 9A, and the volume of the pseudo backtrack sound is determined. Is determined according to the basic envelope shown in FIG. Alternatively, when using the envelope shown in FIG. 9B, the temporal change in the volume of the player input sound is determined according to the solid envelope shown in FIG. The temporal change in volume is determined according to the basic envelope shown in FIG.
[0099]
Then, the game device generates a player input sound by reproducing the player input sound data based on the player input at the timing notified by Pop 31, the timing data stored in the RAM 3, and the determined volume. (Step S15). Further, the game device generates a pseudo backtrack sound (step S16).
[0100]
Next, the game device determines whether or not the music has ended (step S17). If the music has not ended, the game device returns to step S13 and repeats the processing of steps S13 to S17. On the other hand, when the music ends, the game device ends the music sound distinction process.
[0101]
As described above, according to the present embodiment, the volume of the player input sound is not changed, but the volume is changed in consideration of time. Sound and pseudo backtrack sound can be distinguished.
[0102]
[Third embodiment]
Next, a third embodiment of the music sound distinction process will be described with reference to FIGS. In the third embodiment of the music sound distinction processing, the player input sound and the pseudo backtrack sound are distinguished from each other for audibility by not reproducing the reverberation sound data included in the player input sound data but reproducing only the original sound data.
[0103]
FIG. 11A shows an example of sound data. The sound data represents the time change of the amplitude, and has two types of original sound data and reverberation sound data. The original sound is a sound that directly arrives from the sound source, and the original sound data has a large amplitude. On the other hand, a reverberant sound is a sound that is generated from a sound source and then reflected by a barrier or the like, and the reverberant sound data has a small amplitude.
[0104]
In general, the reverberant sound has the effect of making the sound mellow and making the sound audible from the back. Therefore, when the reverberation sound data included in the sound data is not reproduced, but only the original sound data is reproduced, the sound becomes a dry sound, and it sounds as if it was pronounced in front.
[0105]
Therefore, in this embodiment, the game device does not reproduce the reverberation sound data included in the player input sound data, but reproduces only the original sound data. On the other hand, with respect to the pseudo backtrack sound data, not only the original sound data but also reverberation sound data for a time equivalent to the reverberation sound data of the backtrack sound data is reproduced. According to this, the player input sound that is generated by reproducing the player input sound data becomes a dry sound and sounds as if it was generated in front of the player. On the other hand, the pseudo backtrack sound generated by reproducing the pseudo backtrack sound data reproduces not only the original sound data but also reverberation sound data equivalent to the backtrack sound data. Easy to be recognized. Therefore, the game apparatus can distinguish between the player input sound and the pseudo backtrack sound. As a result, it is possible to enhance the feeling that the player is playing.
[0106]
Next, the function of the game device in the third embodiment of the music sound distinction process of the present invention will be described. FIG. 6 is a functional block diagram of the game device according to the present embodiment. In FIG. 6, the game apparatus of the third embodiment includes a backtrack sound reproducing means 50, a pseudo backtrack sound reproducing means 51, and a player input sound reproducing means 52. The DVD-ROM 15 stores backtrack sound data 61, music sound data 62, timing data 63, and a music sound distinction processing program 64. Each function shown in FIG. 6 is realized when the CPU 1 or the GPU 4 shown in FIG. 1 executes the music sound distinction processing program 64. In addition, description is abbreviate | omitted for convenience about the part which overlaps with the structure of 1st Example of a music sound distinction process.
[0107]
Next, a third embodiment of the music sound distinction process will be described with reference to the flowchart of FIG. The processing described below is executed by the CPU 1 based on programs and data stored in the DVD-ROM 15 shown in FIG.
[0108]
In FIG. 12, the game device first determines allocation of player input sound data or pseudo backtrack sound data to music sound data based on the difficulty level of the music (step S22).
[0109]
The game apparatus reads backtrack sound data, player input sound data, and pseudo backtrack sound data from the DVD-ROM 15 and stores them in the RAM 3. (Step S23). At this time, only the original sound data of the player input sound data is stored in the RAM 3 as the player input sound data. That is, reverberant sound data is not stored. On the other hand, as the pseudo backtrack sound data, both the original sound data and the reverberation sound data of the pseudo backtrack sound data are stored in the RAM 3. Therefore, in this case, the used capacity of the RAM 3 can be saved for the reverberant sound data included in the player input sound data.
[0110]
Next, the game device generates a backtrack sound by reproducing the backtrack sound data stored in the RAM 3 (step S24). The game device reproduces the player input sound by reproducing only the original sound data included in the player input sound data based on the player input at the timing notified by Pop-kun 31 and the timing data stored in the RAM 3. Pronunciation (step S25). Furthermore, the game device generates a pseudo backtrack sound by reproducing the original sound data and the reverberation sound data included in the pseudo backtrack sound data (step S26).
[0111]
Next, the game device determines whether or not the music has ended (step S27). If the music has not ended, the game device returns to step S24 and repeats the processing of steps S24 to S27. On the other hand, when the music ends, the game device ends the music sound distinction process.
[0112]
As described above, according to the music sound distinction process of the present embodiment, the game device does not reproduce the reverberation sound data of the player input sound, but reproduces only the original sound data, thereby reproducing the player input sound and the pseudo backtrack. It is possible to distinguish sounds. Therefore, the feeling that the player is playing by himself / herself can be enhanced.
[0113]
In the above example, the reverberation sound data of the player input sound data is not reproduced, but only the original sound data is reproduced. Instead, the reverberation sound data included in the player input sound data not reproduced is backed up. It is also possible to reproduce the sound from the sound source assigned to generate the track sound. According to this, since the reverberation sound data of the player input sound is generated at a predetermined timing, the uncomfortable feeling of the entire music can be slightly relieved compared with the case where the reverberation sound data is not reproduced at all.
[0114]
In this embodiment, the music sound data has two types of reverberation sound data and original sound data. However, the present invention is not limited to this, and the music sound data may have only the original sound data. In this case, the player input sound data allocated in step S22 reproduces the original sound data of the player input sound data without passing through the effector. On the other hand, the pseudo backtrack sound data allocated in step S22 reproduces the original sound data of the pseudo backtrack sound data through the effector. Here, the effector is provided in the game device and can add reverberation at the time of sound generation by processing sound that is generated based on input original sound data. That is, by reproducing the original sound data through the effector, it is possible to obtain the same effect as reproducing the reverberant sound data. Therefore, the player input sound is a dry sound, and the pseudo backtrack sound is easily recognized as a part of the backtrack sound.
[0115]
[Fourth embodiment]
Next, a fourth embodiment of the music sound distinction process will be described with reference to FIGS. In the fourth embodiment, by changing the phase of the player input sound data, the player input sound and the pseudo backtrack sound are distinguished from each other for hearing.
[0116]
In addition to “volume” and “sound quality”, the “direction” in which the sound comes in can be considered as an element when a person judges the sound. Usually, a person or an animal can estimate not only the direction from the surrounding reverberation sound but also the distance to the sound source to some extent. A virtual sound source position estimated on the basis of sound recognized for hearing is called a sound image. In other words, when a person listens to a sound, it can be said that the person has one sound image for that sound. From this, the game apparatus can distinguish the player input sound and the pseudo backtrack sound from the viewpoint of audibility by controlling the sound image position using the amplitude difference or time difference of the sound data. It is assumed that the game device is a stereo system. Here, the stereo method is a method of generating a three-dimensional sound by reproducing separate sound data in the left channel speaker 10a and the right channel speaker 10b arranged on the left and right.
[0117]
FIG. 11A shows sound data reproduced by the left channel speaker 10a, and FIG. 11B shows sound data reproduced by the right channel speaker 10b. The sound data represents the time change of the amplitude, and has two types of original sound data and reverberation sound data. In FIG. 11B, the same sound data phase as in FIG. 11A is delayed by θ seconds. That is, the DVD-ROM 15 stores the same sound data and time θ as information in FIG. 11A in order to reproduce the sound data in FIG.
[0118]
While the game is in progress, the game device reads the music sound data from the DVD-ROM 15, assigns it to the player input sound data or the pseudo backtrack sound data based on the difficulty level of the music, and stores it in the RAM 3. At this time, the game device stores music sound data, which is sound data as shown in FIG. 11A, in the RAM 3 as player input sound data to be reproduced by the left channel speaker 10a. Further, the game apparatus stores the music sound data, which is sound data as shown in FIG. 11B, and the information on the time θ in the RAM 3 as player input sound data reproduced from the right channel speaker 10b.
[0119]
According to this, since the phase of the pseudo backtrack sound that is generated by reproducing the pseudo backtrack sound data and the player input sound that is generated by reproducing the player input sound data are different in phase, the position of the sound image felt by the player Will be different. In this way, it is possible to distinguish the player input sound and the pseudo track sound in terms of audibility. This is because the position of the sound image is changed by generating the player input sound reproduced from the right channel speaker 10b later than the pseudo backtrack sound.
[0120]
Note that the present embodiment is not limited to the above example, and can be applied to a monaural system. For example, there are various methods that make it possible to distinguish the pseudo backtrack sound from the player input sound using the phase, such as reproducing the pseudo backtrack sound data as normal phase and the player input sound data as reverse phase. The stereo system is not limited to the case where two channel speakers are arranged on the left and right, and a plurality of channel speakers may be arranged.
[0121]
Next, the function of the game device in the fourth embodiment of the music sound distinction process will be described. FIG. 6 is a functional block diagram of the game device in the fourth embodiment of the music sound distinction process.

[0122]
The player input sound changing unit 53 changes the phase of the player input sound data 71 by changing the reproduction timing of the player input sound data 71 by θ time.
[0123]
Next, a fourth embodiment of the music sound distinction process will be described with reference to the flowchart of FIG. The processing described below is executed by the CPU 1 based on programs and data stored in the DVD-ROM 15 shown in FIG.
[0124]
In FIG. 13, the game device first determines allocation of player input sound data or pseudo backtrack sound data to music sound data (step S32). Then, the game device reads backtrack sound data from the DVD-ROM 15 and stores it in the RAM 3. Further, the game device stores music sound data assigned as pseudo backtrack sound data. Further, the game device stores music sound data assigned as player input sound data. Specifically, the game device stores music sound data, which is sound data as shown in FIG. 11A, in the RAM 3 as player input sound data to be reproduced by the left channel speaker 10a. Further, the game apparatus stores the music sound data, which is the sound data as shown in FIG. 11B, and the information on the time θ in the RAM 3 as player input sound data to be reproduced by the right channel speaker 10b (step S33).
[0125]
Next, the game device generates a backtrack sound by reproducing the backtrack sound data stored in the RAM 3 (step S34). Then, the game device reproduces the player input sound data as shown in FIG. 11A based on the player input at the timing notified by Pop-kun 31 and the timing data stored in the RAM 3. A player input sound is generated from the left channel speaker 10a. In addition, the game device reproduces the player input sound data as shown in FIG. 11B based on the player input at the timing notified by Pop-kun 31 and the timing data, so that the player input sound is Sound is generated from the channel speaker 10b (step S35). That is, the player input sound generated from the right channel speaker 10b is generated at a timing later by the time θ than the player input sound generated from the left channel speaker 10a. Further, the game device generates a pseudo backtrack sound by reproducing the pseudo backtrack sound data stored in the RAM 3 (step S36).
[0126]
Next, the game device determines whether or not the music has ended (step S37). If the music has not ended, the game device returns to step S34 and repeats the processing of steps S34 to S37. On the other hand, when the music ends, the game device ends the music sound distinction process.
[0127]
According to the present embodiment, the game device distinguishes both by changing the positions of the sound images by making the phases of the player input sound and the pseudo backtrack sound different. Therefore, the feeling that the player is playing by himself / herself can be enhanced.
[0128]
[Fifth embodiment]
Next, a fifth embodiment of music sound distinction processing will be described with reference to FIGS. 6 and 14 to 17. In the fifth embodiment, the player input sound and the pseudo backtrack sound are distinguished from each other for audibility by changing the frequency band of the player input sound based on the frequency band of the backtrack sound.
[0129]
In the music game, the backtrack sound data and the music sound data stored in the DVD-ROM 15 are set so that there is no sense of incompatibility when played back. Therefore, in this embodiment, the game apparatus analyzes the frequency distribution of the backtrack sound within a predetermined time width, and plays the player input sound so that the player input sound is generated at a frequency with a small distribution in the time width. The frequency distribution of is changed. In this way, by performing equalization processing for changing the sound quality of the player input sound in real time, the player input sound and the pseudo backtrack sound are distinguished from each other in terms of audibility. Specifically, the player input sound is conspicuous because it is generated at a sparse frequency rather than a dense frequency when generating a backtrack sound or a pseudo backtrack sound. Therefore, the player can easily distinguish the player input sound and the pseudo backtrack sound in terms of hearing.
[0130]
FIG. 14 is an example of player input sound information. The player input sound information analyzes the frequency distribution and stores the volume level and ratio of the player input sound for each frequency band. FIG. 15 is an example of backtrack sound information. The backtrack sound information analyzes the frequency distribution and stores the ratio of the backtrack sound for each frequency band within a predetermined time width. Note that the player input sound information and the backtrack sound information are stored in the DVD-ROM 15.
[0131]
FIG. 16A is a calculation example for calculating the ratio average value of the backtrack sound. FIG. 16B is an adjusted volume level tabulation table. The post-adjustment volume level summary table includes a frequency, a difference from the backtrack sound volume average value, a player input sound volume level, and a player input sound adjusted volume level.
[0132]
Specifically, first, the game device calculates the ratio average value of the backtrack sound based on the player input at the timing notified by Pop-kun 31, player input sound information, and backtrack sound information. Therefore, the game apparatus confirms the frequency band of the player input sound based on the player input sound information. According to the player input sound information shown in FIG. 14, the frequency band of the player input sound is “2.0 to 7.0 kHz”. This is because the frequency band with a ratio of 0% is excluded. Then, based on the timing of the player input sound, the game device calculates the average value of the ratio of the frequency band “2.0 to 7.0 kHz” in the backtrack sound information as the ratio average value. Here, when the timing of the player input sound is the backtrack sound “000 to 001 seconds”, the ratio of the frequency band “2.0 to 7.0 kHz” is a value surrounded by the thick line 40 in FIG. 15. Accordingly, the ratio average value of the backtrack sound is “12%” as shown in the calculation formula of FIG. In this way, the game device calculates the ratio average value of the backtrack sound.
[0133]
Next, the game device calculates an adjusted volume level of the player input sound based on the ratio average value of the backtrack sound. Therefore, the game device calculates the difference between the ratio of the backtrack sound and the ratio average value for each frequency band, as shown in FIG. For example, the ratio of the backtrack sound in the frequency band “2.0 to 3.0 kHz” is “8%” according to the backtrack sound information shown in FIG. Since the ratio average value of the backtrack sound calculated by the calculation formula of FIG. 16A is “12%”, the difference is “4%” as shown in FIG. Further, according to the backtrack sound information shown in FIG. 15, the ratio of the backtrack sound in the frequency band “3.0 to 4.0 kHz” is “15%”. Accordingly, the difference from the ratio average value of the backtrack sound is “−3%” as shown in FIG.
[0134]
Then, the game device calculates the volume level after adjusting the player input sound based on the difference from the ratio average value of the backtrack sound for each frequency and the player input sound volume level. For example, in the frequency band “2.0 to 3.0 kHz”, the volume level of the player input sound is “33” as shown in FIG. Further, the difference from the ratio average value of the backtrack sound is “4% (0.04)”. Since the volume level after adjusting the player input sound can be calculated by “(1 + difference from the average backtrack sound ratio) × the volume level of the player input sound”, the frequency band “2.0 to 3.0 kHz”. As shown in FIG. 16B, the volume level after adjusting the player input sound in “34” is “34.32.”
[0135]
For example, in the frequency band “3.0 to 4.0 kHz”, the volume level of the player input sound is “24” as shown in FIG. Further, the difference from the ratio average value of the backtrack sound is “−3% (−0.03)”. Therefore, the volume level after player input sound adjustment in the frequency band “3.0 to 4.0 kHz” is “23.28” as shown in FIG. Thus, the game device calculates the volume level after adjusting the player input sound for each frequency.
[0136]
Then, the game device generates a player input sound at the volume level after adjusting the player input sound. Note that the game apparatus performs processing in real time based on the player input in accordance with the timing notified by Pop-kun 31 in order to calculate the volume level after adjusting the player input sound.
[0137]
According to this, the game device analyzes the frequency distribution of the backtrack sound within the predetermined time width, and the frequency distribution of the player input sound so that the player input sound is generated at a frequency with a small distribution in the time width. To adjust the volume level. Therefore, the player input sound is a conspicuous sound because it is generated at a sparse frequency instead of a dense frequency when generating a backtrack sound or a pseudo backtrack sound.
[0138]
In the above example, the player input sound is made conspicuous by performing equalization processing based on the frequency distribution of the player input sound and the backtrack sound. However, the present invention is not limited to this, and may be based on the frequency distribution of the player input sound and the pseudo backtrack sound.
[0139]
Also, in the above example, there is no particular restriction when calculating the volume level after adjusting the player input sound, but if the frequency distribution and volume level are significantly different from those before the adjustment, the music will be uncomfortable. Therefore, it is possible to provide a predetermined restriction. For example, if the difference from the average value of the backtrack sound ratio is within 10% in the upper and lower directions, the volume level after adjusting the player input sound is calculated based on the difference. If there is, the volume level after the player input sound adjustment is not changed. Further, when the sum of the volume levels after adjusting the player input sound is significantly different from the sum of the volume levels before the adjustment, correction may be performed.
[0140]

Further, the game device generates a backtrack sound by reproducing the backtrack sound data (step S45).
[0148]
Next, the game device calculates the volume level after adjusting the player input sound based on the average value of the backtrack sound ratio calculated in step S44 and the player input sound volume level (step S46). Then, the game device reproduces the player input sound data based on the player's input at the timing notified by Pop-kun 31 and the timing data stored in the RAM 3, so that the player at the adjusted volume level calculated in step S46. An input sound is generated (step S47). Further, the game device generates a pseudo backtrack sound by reproducing the pseudo backtrack sound data stored in the RAM 3 (step S48).
[0149]
Next, the game device determines whether or not the music has ended (step S49). If the music has not ended, the game device returns to step S44 and repeats the processing of steps S44 to S49. On the other hand, when the music ends, the game device ends the music sound distinction process.
