[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game device for generating at least a game sound and an information storage medium used for the game device.

[0002]

2. Description of the Related Art In a game device, game effects and information transmission by game sounds including game music, sound effects, voices (narrations), etc. are used to make the game interesting, exciting, and realistic. It plays a major role in improving the feeling. Therefore, how to effectively produce game effects and transmit information using game sounds is one of the reasons.
There are two technical issues.

However, if the game device is installed in a place where the ambient sound is loud, the game sound output from the game device is blocked by the ambient sound. As a result, a situation in which information to be transmitted by the game sound does not reach the player or the audience occurs, and the fun, excitement, and realism of the game are reduced.

[0004] As one method of solving such a situation, a method of simply increasing the volume of the game sound as the ambient sound increases is conceivable, but this method may cause an increase in noise.

The present invention has been made to solve the above technical problems, and an object of the present invention is to provide a game apparatus and an information storage medium capable of generating an appropriate game sound according to ambient sounds. Is to provide.

[0006]

In order to solve the above-mentioned problems, the present invention relates to a game apparatus for generating a game sound, comprising: means for detecting ambient sound; and means for analyzing the detected ambient sound. Means for assisting the transmission of information performed by the game sound based on the analysis result of the ambient sound by transmitting information other than the sound.

According to the present invention, ambient sounds around the game device are detected, and for example, the magnitude and frequency characteristics of the ambient sounds are analyzed. Then, based on the result of the analysis, the auxiliary means assists in transmitting information by game sound. This assistance is performed using information other than sound, for example, visual information and bodily sensation information. For example, when ambient sound is loud and communication of information by game sound is hindered, assistance using visual information, bodily sensation information, and the like is performed so that the information is transmitted to the player in some form. This makes it possible to generate an appropriate game sound according to the ambient sound.

Further, the present invention is characterized in that the information other than the sound is visual information. As the transmission of the visual information, for example, it is possible to consider displaying an image on a display or illuminating a light or an LED. By assisting using the visual information, the player can easily grasp the information to be transmitted to the game sound even when the game sound cannot be heard well due to the ambient sound.

Further, the present invention is characterized in that the visual information is character information corresponding to a sound included in a game sound. By using the character information in this manner, the player can easily recognize the information transmitted by the sound of the game sound.

[0010] The present invention is also characterized in that the information other than the sound is bodily sensation information given to a player. As the transmission of the bodily sensation information, it can be considered that the device on which the player rides is shaken or the temperature around the player or the flow of air is changed. By assisting using the bodily sensation information, the player can easily grasp the information to be transmitted to the game sound even when the game sound cannot be heard well due to the ambient sound.

[0011] The present invention also provides means for detecting ambient sound,
It is characterized by including means for analyzing the detected ambient sound, and means for changing the volume balance of a plurality of sounds included in the game sound based on the analysis result of the ambient sound.

Then, based on the analysis result, the volume balance of a plurality of sounds included in the game sound, for example, each performance part of the game music, the effect sound, and the sound changes. By doing so, it is possible to enhance the audibility of the game sound while minimizing noise.

Further, the present invention is characterized in that, when the ambient sound is loud, the volume of at least one of the sound and the sound effect included in the game sound is increased. According to the present invention, when the ambient sound increases, for example, only the volume of the sound or the sound effect increases. Alternatively, the volume of the voice or the sound effect changes at a higher rate of change than the rate of change of the other sounds included in the game sound. By doing so, even when the surrounding sound becomes loud, the player can recognize information to be conveyed by voice or sound effect.

Further, the present invention is a game device for generating a game sound, comprising: means for detecting an ambient sound; means for analyzing the detected ambient sound;
Means for changing at least one of a timbre, a pitch, and a reproduction speed of at least one sound included in the game sound.

According to the present invention, ambient sounds around the game device are detected, and the ambient sounds are analyzed. Then, based on the analysis result, the timbre, pitch or reproduction speed of the sound included in the game sound changes. Note that the game sound may be composed of only one sound. According to the present invention, the sound changes to a timbre, a pitch, and a reproduction speed that can be recognized by the player even when the surrounding sound exists. Thereby, the audibility of the game sound can be improved.

Further, the present invention is characterized in that a tone color, a tone pitch and a playback speed corresponding to the detected ambient sound are selected from a plurality of tone colors, tone pitches and playback speeds prepared in advance. And By doing so, it is possible to easily change the timbre, pitch, and reproduction speed.

Further, according to the present invention, when the ambient sound is loud, the reproduction speed of the sound included in the game sound is reduced. In this way, even if the ambient sound is loud,
Information to be conveyed by voice can be reliably transmitted to the player.

A feature of the present embodiment is that the assisting unit 140 assists the transmission of information performed by the game sound by transmitting information other than sound based on the analysis result of the surrounding sound by the analyzing unit 110. As the information other than the sound in this case, for example, various information such as visual information such as image information, sensation information given to the player, and the like can be considered.

For example, in FIGS. 2A and 2B, information transmission by game sound is assisted by transmission of visual information.

That is, when it is determined based on the analysis result of the analysis unit 110 that the ambient sound is low, only the game sound from the sound output unit 130 is used as shown in FIG.
The information “Shoot! Defeat!” Is transmitted to the player.

On the other hand, when it is determined that the ambient sound is loud based on the analysis result of the analysis unit 110, as shown in FIG. 20 (transmission of character information). That is, "Shoot! Defeat!" From the sound output unit 130.
The player can know the contents of the information by looking at the subtitles 20 even if the user does not hear the voice of the subtitle 20. As a result, even when the ambient sound is loud, it is possible to reliably and accurately convey information to be conveyed by the game sound to the player. In FIG. 2 (B), the information “Shoot! Defeat!” Is transmitted by both the game sound and the subtitles 20. However, the information may be transmitted only by the subtitles 20 without outputting the game sound. . However, game sounds and subtitles 2
If both of 0 are used, the auditory information and the visual information complement each other, so that the audibility of the game sound can be further improved.

In FIG. 3, information transmission by game sound is assisted by transmission of bodily sensation information. That is, in the game device having the bodily sensation mechanism shown in FIG. 3, the player 30 rides on the vehicle 18 while watching the image projected on the display 12 and listening to the game sound flowing from the speakers 32 and 33, Operate 16
For example, by pedaling the pedal 16, the moving body 40 projected on the display 12 moves in the object space,
By operating the handle 14, the moving direction of the moving body 40 changes. In this game device, the vehicle 18 swings in the directions indicated by F and G, for example, or the wind comes out of the vent 34 according to the game situation. Thereby, the player enjoys the game not only with the visual information and the auditory information transmitted by the display 12 and the speakers 32 and 33, but also by the bodily sensation information transmitted by the swing of the vehicle 18 and the wind from the vent 34. be able to.

In this embodiment, the bodily sensation information is changed according to the analysis result of the surrounding sound. For example, when the moving object 40 projected on the display 12 is about to collide with the cliff 42, warning sounds including sound effects and sounds are output from the speakers 32 and 33.

When the ambient sound is low, the moving object 4
Warning information that 0 is about to collide with the cliff 42 is transmitted to the player only by a warning sound from the speakers 32 and 33.

The method of assisting using visual information is not limited to the method using captions (character information) as shown in FIGS. 2 (A) and 2 (B). For example, an image of a character or the like displayed on the screen may be changed based on an analysis result (a size, a frequency characteristic, and the like) of the surrounding sound. For example, if the ambient sound is loud, the gesture of the character may be exaggerated. Alternatively, information transmission by game sound may be assisted by changing the light amount and display contents of the lamp 36 and the LED panel 38 shown in FIG.

The method of assisting using the sensation information is not limited to the method described with reference to FIG. For example, assistance may be provided by vertical movement or vibration of the vehicle 18, or by changing the temperature.

Next, an example of a hardware configuration capable of realizing the first embodiment will be described with reference to FIG.

The information storage medium 430 mainly stores programs, image data, sound data, and the like.
ROM, game cassette, IC card, MO, FD, D
VD, memory, etc. are used. For example, a home-use game device uses a CD-ROM and a game cassette, and a business-use game device uses a memory such as a ROM.

The control device 400 corresponds to a game controller, an operation panel, and the like, and is a device for inputting a result of a determination made by a player in accordance with a progress of a game to a main body of the device.

In accordance with programs stored in the information storage medium 430, signals input by the control device 400, and the like, the main CPU 402 controls the entire device, performs various data processing, and performs game calculation processing.

Further, the game device has an image generation IC 4
04 and a sound processing IC 414 are provided so that suitable output of sounds and images can be performed. As the image generation IC 404 and the sound processing IC 414, for example, a dedicated IC, a CPU, a DSP, or the like can be used.

The image generation IC 404 includes a main CPU 40
Display 406 based on the instruction from the PC 2 and the program and image data input from the system bus 401.
Is an integrated circuit that generates pixel information to be output to the IC.
As the display 406, a so-called head-mounted display (HMD) can be used.

The control device 408 controls the bodily sensation mechanism 409 based on instructions from the main CPU 402, programs input from the system bus 401, and control data. The bodily sensation mechanism 409 operates under the control of the control device 408, and transmits bodily sensation information to the player by, for example, rocking a vehicle (see FIG. 3) on which the player rides.

The sound processing IC 414 is connected to the main CPU 402

The PCM sound source 416 outputs the game sound to be output based on the processing result of the sound processing IC 414 and the waveform data (data representing the actual physical waveform of the sound) input from the system bus 401. , And outputs the digital signal to the D / A converter 418. The D / A converter 418 converts this digital signal into an analog signal and outputs it to the low-pass filter 420. The output of the low-pass filter 420 is input to the speaker 422 via the amplifier 421, whereby the game sound is output to the outside.

In FIG. 4, a microphone 410 is provided to collect ambient sounds. Ambient sound collected by the microphone 410 is transmitted to the A / D converter 4 via the amplifier 411.
The signal is converted into a digital signal by the A / D converter 412 and input to the sound processing IC 414. Then, the sound processing IC 414 performs digital signal processing based on the input digital signal, and analyzes ambient sounds.

(Embodiment 2) In Embodiment 2, the sound volume balance of the game sound is changed based on the analysis result of the surrounding sound.
This is an embodiment in which the timbre, pitch, and reproduction speed are changed.

FIG. 5 shows an example of a functional block diagram of a game device according to the second embodiment. The difference from FIG. 1 is that FIG.
The sound generation unit 120 includes a volume balance change unit (equalizer) 122, a timbre change unit 124, and a pitch change unit 12.
6. The point that the reproduction speed changing unit 128 is included.

Here, the volume balance change section 122 changes the balance of the volume (sound volume) of a plurality of sounds included in the game sound based on the analysis result of the surrounding sound from the analysis section 110. That is, the game sound is obtained by synthesizing a plurality of sounds such as a sound of each performance part of the game music, a sound effect, and a voice. In the present embodiment, the volume balance of the plurality of sounds is changed based on the analysis result of the surrounding sounds.

For example, if only the volume of the sound or sound effect included in the game sound is increased as the surrounding sound increases, the information to be conveyed by the sound or sound effect can be transmitted to the player reliably and accurately. That is, the audibility of voices and sound effects can be improved. At this time, by keeping the volume of the game music unchanged or by reducing the volume change rate of the game music, the audibility of voices and sound effects can be improved while minimizing noise.

When changing the volume balance, the volume of some performance parts of the game music may be increased. Alternatively, the volume balance may be changed based on an analysis result such as a frequency characteristic instead of the loudness of the surrounding sound. In this case, for example, the volume of a sound having a frequency characteristic similar to that of the surrounding sound is increased.

In this embodiment, the timbre changing section 124, the tone pitch changing section 126, and the reproduction speed changing section 128
The timbre, pitch and reproduction speed of the sound included in the game sound are changed based on the analysis result of the surrounding sound.

For example, the timbre changing section 124 changes the timbre of the sound so that the sound can be heard conspicuously even when the surrounding sound exists. This includes, for example, changing game music, sound effects, and voice to a tone that has a frequency characteristic different from that of the surrounding sound, or changing the tone of the voice so that it has an accent or intonation that is easy to hear even in a large surrounding sound. Can be realized.

The sound pitch changing section 126 changes the sound pitch so that the sound can be heard conspicuously even when the surrounding sound exists. This can be realized, for example, by changing the pitch of the game music, the sound effect, and the voice so as to have a frequency characteristic different from that of the surrounding sound. That is, when the ambient sound has a low frequency component, the pitch of the sound is changed so that the frequency components of the game music, the sound effect, and the voice become high. Conversely, if the surrounding sound has a high frequency component, the pitch of the sound is changed so that the frequency components of the game music, the sound effect, and the sound become low.

The reproduction speed changing section 126 changes the reproduction speed of the sound so that the sound can be heard conspicuously even when the surrounding sound exists. This depends, for example, on the results of the analysis of the ambient sound,
This can be realized by changing the audio playback speed. That is,
When the ambient sound is low, the sound is reproduced at a normal reproduction speed, and when the ambient sound is high, the sound is reproduced at a low reproduction speed. As a result, words and the like are spoken slowly, so that the audibility of the sound can be improved.

FIG. 6 shows an example of a hardware configuration of a game device capable of realizing the second embodiment. Hereinafter, a detailed example of the second embodiment will be described with reference to FIG.

As shown in FIG. 6, a program, sequence data, a volume table, a tone table, a pitch table, and a reproduction speed table are input to the sound processing IC 414. Ambient sound is detected by the microphone 410,
The signal is converted into a digital signal by the A / D converter 412.
The sound processing IC 414 analyzes the ambient sound based on the digital signal, and updates the sequence data based on the analysis result and the various tables. Then, the updated sequence data is output to PCM sound source 416. The PCM sound source 416 generates a digital signal of a sound to be output based on the updated sequence data and the waveform data. Then, the game sound is output from the speaker 422 to the outside via the D / A converter 418 and the low-pass filter 420.

FIG. 7 shows an example of sequence data. The part indicated by H in FIG. 7 is a part that determines the melody (pitch, rhythm) of the sound (sound constituting game music) output from each channel. Similarly, the portions indicated by I, J, K, and L are portions that determine the volume, tone, pitch, and reproduction speed of the sound output from each channel.

In FIG. 7, channels 1, 2, and 3 are assigned to game music performance parts, and each channel (each performance part) outputs a drum, violin, and flute tone. Become.

Channel 4 is sound effect, channel 5
Is assigned to voice. That is, the channel 4 outputs a sound effect of “Bibibee”, and the channel 5 outputs a sound of “Shoot!

In FIG. 7, the volume of channels 1 to 5
The pitch and playback speed are all set to normal. That is, the volume is set to a medium level, the pitch of the sound is set to a medium level, and the reproduction speed is set to a medium speed.

FIG. 8 shows an example of the volume table. The sound volume table stores data on how to change the sound volume of each channel according to the analysis result of the surrounding sound, for example, the loudness of the surrounding sound. For example, in FIG. 8, the volume of channels 1 to 3 (game music) remains normal and does not change even when the ambient sound increases. On the other hand, channels 4 and 5 (sound effects and voices) increase as the surrounding sounds increase. That is, by using a volume table as shown in FIG. 8, it is possible to change the volume balance of a plurality of sounds (sounds of each performance part of the game music, sound effects, and sounds) included in the game sound.

When the ambient sound becomes loud, it does not matter much if the game music cannot be heard well.
On the other hand, the sound and the sound effect have a role of transmitting various information to the player, and thus it is desirable that the sound and the effect sound become louder when the surrounding sound becomes louder. According to the present embodiment, when the ambient sound is increased, the sound and the sound effect can be increased without increasing (or without increasing) the volume of the game music. This makes it possible to maintain the audibility of voices and sound effects even when the ambient sound becomes loud, to prevent the game sound from becoming unnecessarily loud, and to minimize noise.

FIGS. 9A, 9B, and 9C show examples of a tone color table, a pitch table, and a reproduction speed table.

As shown in FIG. 9A, the tone color table stores the tone color of each channel according to the analysis result of the surrounding sound.
That is, data on how to change the waveform number is stored. Note that this waveform number corresponds to the PCM in FIG.
The sound source 416 specifies which waveform data to use. The waveform data is data that defines a physical waveform of each sound such as a drum, violin, flute, sound effect, and voice.

As shown in FIG. 9B, the pitch table stores data on the pitch of each channel, that is, how to change the key according to the analysis result of the surrounding sound. Have been. For example, if the key of channel 1 is set high, the pitch of the melody output from channel 1 is increased overall.

As shown in FIG. 9C, the reproduction speed table stores data on how to change the reproduction speed of the sound of each channel in accordance with the analysis result of the surrounding sound. For example, if the reproduction speed of the channel from which sound is output is increased, the user speaks faster, and if the reproduction speed of the channel is decreased, the user speaks slowly.

When the reproduction speed is changed in this way, it is desirable to lower the reproduction speed of the sound included in the game sound as the surrounding sound increases. FIG. 10 shows an example of the reproduction speed table in this case. When the ambient sound is louder, the sound is usually hard to hear. According to the present embodiment, as the ambient sound increases, the playback speed of the sound decreases,
Speak slowly. This makes it easier for the player to grasp the information to be conveyed by voice, and it is possible to improve the audibility of the voice.

By preparing the tone color table, the tone pitch table, and the reproduction speed table as described above, the tone colors of the sounds included in the game sound (sounds output in each channel) based on the analysis result of the ambient sound. , The pitch of the sound and the reproduction speed can be changed. As a result, it is possible to generate an appropriate game sound according to the ambient sound, and it is possible to improve the audibility of the game sound while minimizing noise.

In the method using the above various tables,
By selecting the tone, pitch and playback speed corresponding to the detected ambient sound from among a plurality of tone colors, pitches and playback speeds prepared in advance, the tone, pitch and playback can be selected. The speed is changing. However, the method of changing the timbre, pitch, and reproduction speed is not limited to the above method. For example, the timbre, pitch, and reproduction speed may be changed by digital signal processing using a DSP or the like, filtering processing using an analog filter circuit, or the like.

As the analysis result of the ambient sound, not only the magnitude of the ambient sound but also various other characteristics such as the frequency characteristics of the ambient sound can be used.

Next, an example of the processing of the second embodiment will be described with reference to the flowchart shown in FIG.

First, the sound processing IC 414 of FIG. 6 retrieves the sequence data of the channel to be processed (step S1). For example, when processing channel 1, the melody, volume, timbre, pitch, and reproduction speed (M1 to M5 in FIG. 7) of channel 1 are subtracted.

The volume, timbre (waveform number), pitch (key), and playback speed of the channel to be processed next are analyzed based on the analysis results of the surrounding sounds, volume table, tone color table, tone pitch table, and playback speed table. (Step S
2). For example, if the ambient sound is loud, channel 5
(Sound) is set to a loud volume (see FIG. 8) and a slow playback speed (see FIG. 10). Alternatively, the tone of the channel 5 may be changed to a sound that is easier to hear, or the pitch of the sound may be increased.

Next, the sequence data shown in FIG. 7 is updated based on the volume, tone, pitch and reproduction speed determined in step S2 (step S3). Then, the updated sequence data is output to the PCM sound source 416 in FIG. 6 (step S4). Next, it is determined whether or not the processing for all channels has been completed (step S5). If it has been completed, the process returns to the first channel (step S
6) If not completed, the process proceeds to the next channel (step S7).

Next, application examples of the first and second embodiments to various game apparatuses will be described.
