Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sound processing method, a game system, and a recording medium suitable for application to a game system using an optical disk, a magnetic disk, and a semiconductor memory in which game data is recorded.
[0002]
[Prior art]
Many game systems have been proposed. A system composed of a home-use machine and a television monitor, a business-use machine, a personal computer or a system composed of a workstation, a display, and an audio output device. Each of these systems includes a controller for operation by the player, a recording medium on which game data including game program data and data such as images and sounds, and generation of sounds and images based on the game program data. The CPU includes a CPU for performing control, a processor for processing an image, a processor for processing sound, a CRT for displaying an image, and a speaker for outputting sound. As the recording medium, there are many CD-ROMs, semiconductor memories, cassettes incorporating semiconductor memories, and the like. The configuration of the game system is as described above.
[0003]
On the other hand, the types of games are steadily increasing, and the contents of games are becoming increasingly complex and diversified. Recently, a parameter indicating intimacy between the game player and the character in the game space is changed according to the operation of the game player, and various messages are sent from the character to the game player according to the value of the parameter. Even games that can be played have appeared. A typical example is a love simulation game. A message is sent from the character to the game player by displaying a balloon on the screen and an image indicating the character in the balloon.
[0004]
[Problems to be solved by the invention]
By the way, in a game in which a character in the game space and the game player communicate with each other in a pseudo manner, the name of the game player registered in advance by the game player is output as sound so that it is called by the character in the game space. It is preferred that This is to allow the game player to be more immersed in the game by making the game player have the illusion that the character in the game space is a person with a personality. In other words, in such a game, it is an essential requirement for a game player to recognize a character in the game space as a person in the game space having a personality.
[0005]
In order to output the name of the game player as audio, a large number of audio data is recorded in advance on a recording medium so as to correspond to the name of most game players, and the name can be selected by the game player. is required. In this way, the game player can select his own name or a name he desires from among a large number of names displayed as characters on the screen. When the name is selected, the CPU of the game system reads the audio data from the recording medium, stores the audio data in the memory, and further stores the address of the audio data on the memory. Then, during the game, the CPU reads the audio data from the storage position on the memory indicated by the address as necessary, and supplies the audio data to a processor for processing the audio. As a result, the name selected by the game player is output as sound from the speaker.
[0006]
However, since the sound data is data prepared in advance by a game manufacturer, the sound output from the speaker is not necessarily sound that the game player likes.
[0007]
Also, since the audio data is recorded in advance on the recording medium for each name, it is impossible to correspond to the names of all game players, and recording by recording the audio data at the time of manufacturing the recording medium The consumption capacity of the medium also increases.
[0008]
The present invention has been made in consideration of the above points, and allows the user's favorite sound to be output by a simple operation and reduces the consumption capacity of the recording medium due to the sound data when the recording medium is manufactured. The object is to deal with conditions specific to the game player.

Color pallet address data indicating the storage position of the color pallet data indicating the color in the buffer 11 and luminance data indicating the luminance of the texture. Among these data, the polygon vertex address data is calculated by the graphics data generation processor 3 based on the polygon absolute coordinate data, the data indicating the movement of the polygon, and the data indicating the movement of the viewpoint position from the CPU 1. Is obtained by performing
[0028]
A drawing command for drawing a normal two-dimensional image includes vertex address data, texture address data, color palette address data, and luminance data indicating the luminance of the texture. Among these data, the vertex address data is coordinate data obtained by the graphics data generating processor 3 converting the vertex coordinate data on the plane from the CPU 1 based on the movement amount data from the CPU 1. . Hereinafter, the drawing process is described in a simplified manner such as “issue a drawing command”.
[0029]
The audio processor 13 stores the PCM or ADPCM data read from the recording medium 30 in the buffer 14 or the main memory 5, and uses the PCM or ADPCM data stored in the buffer 14 or the main memory 5 as a sound source. Of course, the semiconductor memory itself in the recording medium 30 may be a sound source. Then, the voice processor 13 reads the PCM or ADPCM data with a clock having a frequency of 44.1 KHz, for example. The audio processor 13 performs processing such as pitch conversion, noise addition, envelope setting, level setting, and reverb addition on the PCM or ADPCM data read from the buffer 14, the main memory 5 or the recording medium 30.

The cross key is used by the game player to give a command indicating up, down, left, and right to the CPU 1. The start button 22a is used by the game player to instruct the CPU 1 to start game program data loaded from the recording medium 30. The select button 22b is for the game player to instruct the CPU 1 to make various selections regarding the game program data loaded from the recording medium 30 to the main memory 5. The functions of the left key 22L, the right key 22R, and the first to fourth buttons 22c, 22d, 22e, and 22f differ depending on the game program data loaded from the recording medium 30.
[0033]
[Operation]
A power switch (not shown) is turned on, and the game system is powered on. At this time, if the recording medium 30 is loaded in the recording medium driver 19, the CPU 1 reads game data from the recording medium 30 to the recording medium driver 19 based on the operating system stored in the ROM 6. Instruct. Thereby, the recording medium driver 19 reads the image, sound, and game program data from the recording medium 30. The read image, sound, and game program data are supplied to the decoder 17 where error correction processing is performed. The image data that has been subjected to error correction processing in the decoder 17 is supplied to the expansion circuit 7 via the bus 2, where it is supplied to the drawing processor 10 after being subjected to the expansion processing described above. The data is written in the non-display area of the buffer 11 by the processor 10.
[0034]
The audio data that has been subjected to the error correction processing in the decoder 17 is supplied to the main memory 5 or the audio processing processor 13 and written into the main memory 5 or the buffer 14. The game program data that has been subjected to error correction processing in the decoder 17 is supplied to the main memory 5 and written into the main memory 5.

(Fade) has three crossfade functions. In addition, these means are the main subjects of control described in item D and item E.
[0038]
C. Screen display examples (Figs. 3 and 4)
[0039]
3 and 4 are explanatory diagrams showing examples of screen display, respectively. The present embodiment is premised on a game in which a game player and a character in the game space perform pseudo communication, or a game with such a scene. In other words, under the control of the CPU 1, the name of the game player is output as sound from the speaker, and visual processing is performed such that a character in the game space calls the name of the game player. This makes it possible to give the game player the illusion that a character in the game space is calling to the game player. Therefore, the game player can be more immersed in the game. In the following, “the player outputs the name of the game player as a sound and performs a visual process such that the character in the game space calls the name of the game player”, “the character in the game space is the game player "Call your name".
[0040]
In this embodiment, the registration screen shown in FIG. 3A is displayed before the game is started. This registration screen is for the game player to register his name. When the name of the game player is registered, a setting screen shown in FIG. 4 is displayed. This setting screen is for processing the voice data corresponding to the constituent characters of the registered name. The sound data corresponding to the processed characters of the processed name is output as sound from the speaker 16 when it is necessary to “call the name of the game player” while the game is in progress.
[0041]
The registration screen shown in FIG. 3A is displayed at the display position of the image of the 50-note character and the image of the 50-tone character and the “end” character image by operating the cross key of the controller 22 shown in FIG. A cursor image CA displayed to move, an area Ar1 in which an image of the selected character string is displayed, and an “end” character image for instructing the CPU 1 that selection of all characters to be registered has been completed. The area Ar2 is displayed. In this embodiment, each character is determined by pressing the fourth button 22f of the controller 22. For example, in the name “Taro”, the characters “TA”, “RO”, and “U” are first selected by operating the cross key and pressing the fourth button 22f, followed by “END”. Is selected by the operation of the cross key, and then registered by being determined by pressing the fourth button 22f.
[0042]
The setting screen shown in FIG. 4 includes a gauge image Bar1 for setting the sound intensity, a gauge image Bar2 for setting the sound pitch, a gauge image Bar3 for setting the sound speed, and a setting. The CPU 1 is instructed to output an area Ar1 for displaying a sound waveform image corresponding to the intensity, pitch, and speed, an area Ar2 for displaying characters corresponding to the sound, and a set voice output. “Confirmation” character image B1 to be performed, and “End” character image B2 to notify the CPU 1 that all sound settings have been completed.
[0043]
For one character, a waveform display area Ar1, a character display area Ar2, and gauge images Bar1, Bar2, and Bar3 are displayed. In this example, the case where the characters “ta”, “ro”, and “u” are selected is shown. Therefore, the gauge images Bar1, Bar2, and Bar3, the area Ar1, and the area Ar2 are displayed for “ta”, “ro”, and “u”, respectively. Selection of the gauge images Bar1, Bar2, and Bar3 is performed by operating the up key U or down key D of the cross key. The selected gauge images Bar1, Bar2, and Bar3 are displayed with their frame portions highlighted. In this example, the gauge image Bar1 for setting the strength corresponding to the character “ta” is selected. Each time the right key R of the cross key is pressed while the gauge images Bar1, Bar2, and Bar3 are selected, the length of the gauge images Bar1, Bar2, and Bar3 is increased in the right direction, and the value of each parameter is increased. Become. Each time the left key L of the cross key is pressed, the lengths of the gauge images Bar1, Bar2, and Bar3 are reduced in the left direction, and the values of the parameters are reduced. The shape of the waveform image displayed in the waveform display area Ar1 changes according to the change in the parameter value.
[0044]
Incidentally, the strength parameter is, for example, a parameter that determines which character of the name is to be output strongly. The pitch parameter is a parameter that determines the level of voice. The speed parameter is a parameter for determining the sound output time.
[0045]
The above is the registration of the name on the registration screen and the processing of the voice on the setting screen. The internal processing will be described later in detail.
[0046]
D. Control operation by main routine (FIGS. 5 and 6)
[0047]
5 and 6 are flowcharts for explaining the control operation by the main routine of the game.
[0048]
Note that only step S1 is a control operation by the operating system stored in the ROM 6 shown in FIG. The other step is a control operation based on the game program data read from the recording medium 30. Further, as described above, the main body of control by the game program data is each means as a function of the CPU 1 shown in FIG.
[0049]
In step S <b> 1, the recording medium driver 19 reads image, sound, and game program data from the recording medium 30 according to an instruction of the operating system. Of the read data, the program data is stored in the main memory 5. Thus, the CPU 1 has the function shown in FIG. At this time, the image, that is, the texture data is stored in the non-display area of the buffer 11 of the rendering processor 10 and is assigned a texture number. The audio data is stored in the buffer 14 of the audio processor 13 and is assigned audio number data. Normally, not all image and audio data are held in the buffers 11 and 14 in step S1, but for convenience of explanation, it is assumed that all image and audio data are loaded in step S1.
In step S2, the button operation detection unit 1a determines whether or not the start button 22a of the controller 22 has been pressed. If “YES”, the process proceeds to step S3.
[0050]
In step S3, the drawing command issuing unit 1k issues a drawing command indicating drawing of the selected image to the drawing processor 10 shown in FIG. The drawing processor 10 develops the image data of the selected image on the display surface of the buffer 11 based on the drawing command. Thereby, a select image is displayed on the display surface of the television monitor 12.
In step S4, the button operating means 1a determines whether or not the start button 22a of the controller 22 has been pressed. If “YES”, the process proceeds to step S5.
[0051]
In step S5, the CPU 1 sets the selected game. Here, “selected” means that the game player selects a game using the cross key with reference to the selected image displayed in step S3, and then presses the start button 22a. . Here, the “game” includes, in addition to the game itself, for example, a character in a battle game. In short, it is a choice before the game is actually started.
In step S <b> 6, the drawing command issuing unit 1 k issues a drawing command indicating drawing of the initial image of the selected game to the drawing processor 10. In response to this drawing command, the drawing processor 10 writes the image data of the initial image on the display area of the buffer 11. As a result, an initial image is displayed on the display surface of the television monitor 12.
[0052]
In step S7, the CPU 1 resets the flags and variables held in the main memory 5, respectively.
In step S100, voice processing is performed. The voice processing routine S100 will be described in detail later.
[0053]
In step S8, the drawing command issuing unit 1k issues a drawing command indicating that the initial image information is output to the drawing processor 10.
In step S9, the determination unit 1d determines whether the sound output process is performed. Here, “sound output processing” means that, for example, the character calls the name of the game player, that is, the sound data of the name of the game player set on the setting screen shown in FIG. That is.
[0054]
In step S150, an audio output process is performed.
In step S200, other processing is performed.
[0055]
In step S10, the determination unit 1d determines whether there is a save instruction from the game player based on the data indicating the operation content supplied from the button operation detection unit 1a. When the process proceeds to step S11 and it is determined “NO”, the process proceeds to step S9 again.
In step S <b> 11, the CPU 1 supplies various parameter data at the present time to the memory 21 via the interface circuit 20. As a result, various parameter data are stored in the memory 21. Various parameter data stored in the memory 21 is loaded into the main memory 5 when the game is started next time. The CPU 1 starts the game from the previous progress position by using the loaded various parameter data.
[0056]
In step S12, the determination unit 1d determines whether there is a save instruction from the game player based on the data indicating the operation content supplied from the button operation detection unit 1a. If "YES", the process proceeds to step S13. If “NO”, the process proceeds to the step S9 again.
In step S <b> 13, the drawing command issuing unit 1 k issues a drawing command indicating output of image information for termination to the drawing processing processor 10. In response to this drawing command, the drawing processor 10 writes the end image data on the display area of the buffer 11. As a result, an end image is displayed on the display surface of the television monitor 12.
[0057]
E. Control operation by voice processing routine (FIGS. 7 to 10)
[0058]
7 to 11 are flowcharts showing the contents of the voice processing routine shown in FIG.
[0059]
In step S <b> 101, the drawing command issuing unit 1 k issues a drawing command indicating display of the registered image to the drawing processing processor 10. The drawing processor 10 writes the registered image data in the display area of the buffer 11. As a result, a registered image as shown in FIG. 3A is displayed on the display surface of the television monitor 12.
In step S <b> 102, the CPU 1 issues an instruction to the recording medium driver 19 indicating that a table including character data and address data on the recording medium of audio data corresponding to the character data is read. The recording medium driver 19 reads the table data from the recording medium 30 based on the command. The read table data is supplied to the main memory 5 via the decoder 17 and stored in the main memory 5.
[0060]
In step S103, the button operation detection unit 1a determines whether or not the cross key is pressed. If “YES”, the process proceeds to step S104.
In step S104, the drawing command issuing means 1k issues a drawing command indicating that the cursor image CA shown in FIG. 3A is displayed at the position corresponding to the pressed key to the drawing processor 10. The drawing processor 10 writes the cursor image data CA in the display area of the buffer 11. Thereby, the cursor image CA is displayed on the display surface of the television monitor 12. At this time, the CPU 1 temporarily stores position data on the table corresponding to the pressed key. Here, the keys that are effective for changing the position of the cursor image CA are the up key U and the down key D.
[0061]
In step S105, the button operation detection unit 1a determines whether or not the fourth button 22f has been pressed. If “YES”, the process proceeds to step S106, and if “NO”, the process proceeds to step S103 again.
In step S106, the determination unit 1d determines whether or not the selected and determined position is the display position of the character “END”. If “YES”, the voice processing routine S100 is exited and “NO”. If so, the process proceeds to step S107.
[0062]
In step S107, the CPU 1 stores a value indicating the registered number of characters in the main memory 5 as character number data M.
[0063]
In step S108, the computing means 1c obtains a value that is three times the character count data M. Then, the CPU 1 stores a value three times the character count data M in the main memory 5 as the maximum value data Pmax of the pointer data P. Here, the pointer data P indicates the gauge images Bar1, Bar2, and Bar3 of strength, pitch, and speed. For example, gauge images Bar1, Bar2, Bar3, gauge images Bar1, Bar2, Bar3 corresponding to the characters “RO”, gauge images Bar1, corresponding to the characters “U”, corresponding to the characters “TA” shown in FIG. Numbers 1 to 9 are assigned to Bar2 and Bar3. Therefore, for example, when the value of the pointer data P is “9”, the “speed” gauge image Bar3 corresponding to the character “u” is selected. Further, the reason why the maximum value data Pmax of the pointer data P is set to “three times” the number-of-characters data M is that there are three parameters of voice data corresponding to one character.
In step S109, the CPU 1 stores the position data on the table temporarily stored in step S104 in the main memory 5.
[0064]
In step S110, the address data registered in the table for the position data on the table is supplied to the recording medium driver 19 together with the read command. The recording medium driver 19 reads audio data from the recording medium 30 based on the address data. The audio data read from the recording medium 30 is supplied to the main memory 5 via the decoder 17 and stored in the main memory 5.
In step S111, the CPU 1 supplies the recording medium driver 19 with address data in which initial value data of each parameter is recorded and a read command. Thereby, the recording medium driver 19 reads the initial value data of each parameter from the recording medium 30. The read initial value data of each parameter is supplied to the main memory 5 via the decoder 17 and stored in the main memory 5.
[0065]
In step S112, the CPU 1 selects texture address data indicating a gauge image corresponding to the value of the initial value data of each parameter. Here, a plurality of types of gauge images are prepared according to parameter values. For example, when the parameter value is 1 to 10, ten types of gauge images are prepared. Here, since the values of the respective parameters are initial values, the gauge images having the same length are selected in order to display the gauge images Bar1, Bar2, and Bar3 of strength, pitch, and speed, respectively.
In step S113, the image conversion unit 1j converts the sound data into image data. Here, the image conversion means 1j uses the compressed value of the level data for each sample point of the PCM audio data as the value of the y-direction address on the main memory 5, thereby obtaining the level data for each sample of the PCM audio data, Mapping is performed on the main memory 5. At this time, the distance between each sample on the x-axis is, for example, n pixels. Subsequently, the image conversion unit 1j performs an interpolation process between the samples. Thereby, a waveform image as shown in FIG. 4 can be obtained.
[0066]
In step S114, the drawing command issuing unit 1j supplies the drawing processor 10 with a drawing command indicating that the setting image is displayed, and texture address data indicating the waveform image data and the gauge image. As a result, the drawing processor 10 writes the set image data, the waveform image data, and the gauge image data on the display area of the buffer 11. Therefore, the setting image shown in FIG. 4 is displayed on the display surface of the television monitor 12. However, since the values of the parameters are initial values, the lengths of the gauge images Bar1, Bar2, and Bar3 are the same as in the state shown in FIG.
In step S115, the variable setting unit 1b sets the value of the pointer data P to “1”. Then, the drawing command issuing means 1k supplies the drawing processor 10 with the luminance data of the gauge image Bar1, Bar2 or Bar3 at the position corresponding to the value of the pointer data P. Here, the images are the gauge images Bar1, Bar2, and Bar3 shown in FIG. Further, the value of the luminance data is a value close to the maximum value. The drawing processor 10 changes the luminance value of the gauge image Bar1, Bar2 or Bar3 at the position corresponding to the value of the pointer data P to the luminance value indicated by the value of the luminance data. Thereby, the luminance of the gauge image Bar1, Bar2 or Bar3 at the position corresponding to the value of the pointer data P on the display surface of the television monitor 12 is higher than that of the other gauge images Bar1, Bar2 and Bar3.
[0067]

In step S117, the button operation detection unit 1a determines whether or not the up key U has been pressed. If “YES”, the process proceeds to step S118, and if “NO”, the process proceeds to step S122. Here, the upper key U is a key for incrementing the value of the pointer data P.
[0068]
In step S118, the determination unit 1d determines whether or not the value of the pointer data P is the maximum value Pmax of the pointer data P. If “YES”, the process proceeds to step S119, and if “NO”, the process proceeds to step S120. Transition.
In step S119, the computing means 1c substitutes “1” for the pointer data P.
[0069]
In step S120, the computing means 1d adds “1” to the pointer data P.
In step S121, the drawing command issuing unit 1k issues the luminance data of the image at the position corresponding to the value of the pointer data P to the drawing processor 10. The drawing processor 10 changes the luminance of the gauge image Bar1, Bar2 or Bar3 at the position corresponding to the value of the pointer data P based on the luminance data. Thereby, the luminance of the gauge image Bar1, Bar2 or Bar3 corresponding to the value of the pointer P displayed on the display surface of the television monitor 12 is higher than the luminance of the other gauge images Bar1, Bar2 and Bar3. .
[0070]
In step S122, the button operation detection unit 1a determines whether or not the down key D is pressed. If “YES”, the process proceeds to step S123, and if “NO”, the process proceeds to step S126. Here, the lower key D is a key for decrementing the value of the pointer data P.

[0072]
In step S126, the button operation detection unit 1a determines whether or not the fourth button 22f has been pressed. If “YES”, the process proceeds to step S127, and if “NO”, the process proceeds to step S116 again.

[0073]
In step S128, the button operation detection unit 1a determines whether or not the up key U is pressed. If “YES”, the process proceeds to step S129, and if “NO”, the process proceeds to step S132.
In step S129, the calculation means 1c adds the reference value data Ref to the parameter data Pd corresponding to the value of the pointer data P. In this embodiment, the value of the reference value data is “1”.
[0074]
In step S130, the determination unit 1d determines whether the value of the parameter data Pd is larger than the maximum value Pdmax. If “YES”, the process proceeds to step S131, and if “NO”, the process proceeds to step S136. To do.
In step S131, the variable setting unit 1b substitutes the maximum value Pdmax for the parameter data Pd. In this embodiment, the value of the parameter data Pd is set to a value within the range of “1” to “10”. The amount of change in the strength, pitch, and speed is determined according to the value of the parameter data Pd.
[0075]
The strength can be changed by changing the volume value of the PCM audio data. In the case of 16-bit PCM audio data, the 16-bit PCM audio data increases / decreases for each sample by the maximum value / 10 represented by 16 bits with respect to the increase / decrease of "1" in the value of the parameter data Pd. .
The pitch can be changed by thinning out or interpolating PCM audio data. For 16-bit PCM audio data for one character with a sampling time of 1 second and a sampling frequency of 44.1 KHz, the default value of the parameter Pd is set to “0”, and 2 to 3 samples for ± 5 increase / decrease Each level data is thinned out or interpolated for one sample.
The speed is determined by mathematical calculation. For example, the original waveform is Fourier transformed to find the frequency characteristics for each band, and when it is restored by computation (inverse Fourier transform), the number of samples is increased or decreased, or similar waveforms are continuous For example, there is a method in which similar waveforms are extracted and cut or overlapped.
[0076]
In step S132, the button operation detection unit 1a determines whether or not the down key U is pressed. If “YES”, the process proceeds to step S133, and if “NO”, the process proceeds to step S128 again.
In step S133, the calculation unit 1c subtracts the reference value data Ref from the parameter data Pd corresponding to the value of the pointer data P.
[0077]
In step S134, the determination unit 1d determines whether or not the value of the parameter data Pd is smaller than the minimum value Pdmin. If “YES”, the process proceeds to step S135, and if “NO”, the process proceeds to step S136. To do.
In step S135, the variable setting unit 1b substitutes the minimum value Pdmin for the parameter data Pd.
[0078]
In step S136, the drawing command issuing unit 1k issues a drawing command indicating drawing of the gauge image Bar1, Bar2, or Bar3 corresponding to the value of the parameter data Pd to the drawing processor 10. As already described, ten types of gauge images having lengths corresponding to the values of the parameter data Pd from “1” to “10” are prepared. These ten types of gauge images are stored in the non-display area of the buffer 11. The drawing command issuing means 1k supplies the drawing processor 10 with texture address data indicating the address on the buffer 11 in which a gauge image corresponding to the value of the parameter data Pd is stored.
In step S137, the volume unit 1e, the pitch shift unit 1f, or the time axis compression unit 1g changes the audio data according to the value of the parameter data Pd. The relationship between the increase / decrease in the parameter data Pd and the increase / decrease in the audio data is as described above.
In step S138, the image conversion unit 1j converts the sound data into image data indicating a waveform. The conversion process of audio data to image data has already been described.
[0079]

The drawing processor 10 writes image data indicating a waveform on the display area of the buffer 11. As a result, an image showing a waveform is displayed on the display surface of the television monitor 12.
In step S140, the button operation detection unit 1a determines whether or not the fourth button has been pressed. If “YES”, the process proceeds to step S141, and if “NO”, the process proceeds to step S128 again.
[0080]

The audio processor 13 reads audio data from the buffer 14 based on the audio output command, and supplies the audio data to the speaker 16 via the amplifier circuit 15. As a result, the name set by the game player is output from the speaker 16 as sound in a state set by the game player.
[0083]
