FIG. 1 shows an embodiment of the present invention. In the game machine 10 shown in FIG. 1, a game program ROM 12 stores a game program. Operation key 1
At 4, the player performs various operations for playing the game. The game progress control means 16 controls the game program RO
It manages and controls the progress of the game based on the game program stored in M12 and the operation information from the operation keys 14, and controls the reproduction of video and audio. That is, the current progress of the game is determined, the progress (including the operation of the operation keys 14) is stored in the RAM 18, and the video specified by the game program according to the game according to the progress. And video instruction information and audio instruction information to reproduce sound (sound effect, music).

The video instruction information is input to a video processor 18, and a corresponding video signal is output from the video processor 18 and reproduced on a display (CRT, liquid crystal, etc.) 20. The voice instruction information is input to the voice processor 22, and the voice processor 22 outputs a corresponding voice signal (sound effect, music). This sound signal is input to the sound field control means 24, and the reflected sound parameter storage means 2
The reflected sound parameters read from 6 are convoluted with each other to generate reflected sound signals of two left and right channels or four front left, right and rear left and right channels forming a specific sound field. The generated reflected sound signal and the direct sound are transmitted to the speakers 28 and 30 (or speakers 28 and 3 in the case of four channels).
0, 32, 34). The information on the operation status of the operation keys 14 among the information on the current game progress status stored in the RAM 18 includes the operation history (operation total, etc.) of the operation keys 14 and the operation mode (operation frequency, operation speed, operation speed, etc.). Pattern, etc.).

The condition setting means 36 is composed of a ROM, and sets and stores a plurality of combinations of conditions relating to the progress of the game and types of sound fields to be given to sound effects when the conditions are satisfied. The setting example is shown below. (A) In a racing game in which a racing car is run, the sound field given to the exhaust sound is changed depending on whether the vehicle is traveling in an urban area, traveling in a suburb, traveling in a tunnel, or the like. In other words, a sound field with a relatively large reverberation is given to the condition of traveling in an urban area, and a sound field with a small reverberation is given to the condition of traveling in a suburb.
Under the condition that the vehicle is traveling in the tunnel, a sound field with a very large reverberation is provided.

(B) In the racing game, under the condition that the vehicle is running in an urban area and passing through a hairpin curve, a sound field that gives a relatively large reverberation feeling and a different sound field feeling between right and left is provided. . As a result, the sound field feeling of the exhaust sound and the squeaking sound of the tires is different on the left and right, and it is possible to give a sense of tightness such that the acceleration is strongly applied in the lateral direction and pressed.

(C) In a shooting game,
Depending on the conditions of the fighting scene (space, air, ground, underwater, etc.), a different sound field is given to the firing sound of a machine gun or the like to give a sound field feeling appropriate to the scene.

(D) In the shooting game, different sound fields (for example, the firing frequency is high or the firing speed is high) depending on the condition of the operation frequency or operation speed of the operation key 14 (that is, the firing frequency or firing speed of a bullet). The higher the speed, the higher the reverberation feeling, etc.). Further, the sound field can be changed according to the condition of the total operation of the operation keys 14.

(E) In the scenario game, different sound fields are given according to the conditions of the event to be generated. For example,
The sound field of the church is added to the condition that the character dies. When the scene is a cave, a sound field in a reverberant space is provided. In addition, under the condition that fireworks explode in the sky, a sound field that produces a wide delayed reflected sound, such as the sound field of a stadium, is provided.

The reflected sound parameter storage means 26 is composed of a ROM, and stores a plurality of types of reflected sound parameters for realizing various sound fields set by the condition setting means 36. During the progress of the game, the condition judging means 38 compares the information indicating the current game progress sent from the game progress control means 16 with the condition relating to the game progress set in the condition setting means 36. It is determined which condition is satisfied, and if any of the conditions is satisfied, the reflected sound parameter corresponding to the sound field determined in advance by the condition setting means 36 according to the condition is read from the reflected sound parameter storage means 26. The sound field is read out and set in the sound field control means 24, and the sound field control means 24 generates a reflected sound signal such as a sound effect for realizing the sound field.

FIG. 2 shows a configuration example of the sound field control means 24.
Here, four-channel reflected sound signals FL, FR, RL, and RR are generated based on the left and right two-channel L and R audio signals, and the four-channel reflected sound signals are synthesized into two right and left channels and output. Left and right 2 supplied from the audio processor 22 (FIG. 1)
The channel audio signals L and R are input to the reflected sound signal generation means 48 via the input terminals 42 and 44 and the preamplifier 46. The audio signals L and R input to the reflected sound signal generation means 48 are synthesized by the mixer 50 into one channel of LR or L + R. The audio signal synthesized into one channel is converted to a digital signal by an A / D converter 54 via a low-pass filter 52 for preventing aliasing at the time of A / D conversion. Further, in order to give a frequency characteristic to the reflected sound, the digital signal is branched into respective channels and a digital filter 5 is provided.
6, 58, 60, 62. The four-channel audio signals output from the digital filters 56, 58, 60, and 62 are output from the reflected sound generation circuits 64, 6 of each channel.
6, 68, 70.

From the reflected sound parameter storage means 26 (FIG. 1), as reflected sound parameters of various sound fields, for example, FIG.
The reflected sound parameters (such as impulse response data based on the virtual sound source distribution) for each direction (for example, four directions of front left and right and rear left and right) in various sound fields composed of delay time data and gain data as shown in FIG. You. The reflected sound generation circuits 64, 66, 68, and 70 generate a reflected sound signal of the audio signal for each channel by performing a convolution operation with the audio signal based on the reflected sound parameter. These generated reflected sound signals are D / A converted by the D / A converter 74 in a time division multiplex manner. D /
The output signal of the A-converter 74 is distributed to each channel, smoothed by low-pass filters 76, 78, 80, and 82, returned to an analog signal, and output from the reflected sound signal generating means 48.

Among the reflected sound signals in the four directions, the reflected sound signals RL and RR on the left and right sides are added by an adder 83, and then are shifted by + 90 ° and −90 ° by a phase shift circuit 96, so that a phase difference between them is obtained. Are approximately 180 ° and substantially the same level, and two phase- _shifted signals R ₊₉₀ and R _-90 are created. These phase shift signals R
₊₉₀ and R- ₉₀ are added to the front and left reflected sound signals FL and FR by adders 98 and 100, respectively. Further, in the adders 98 and 100, the original audio signals L and R (direct sounds) are added, and the added outputs are guided to output terminals 92 and 94 via power amplifiers 84 and 86.

The left and right two-channel signals guided to the output terminals 94 and 96 are supplied to speakers 28 and 30 (FIG. 1) disposed on the front left and right sides of the player, respectively. As a result, both the direct sound and the reflected sound of the audio signal are output from the speaker 28,
Reproduced from 30. Thereby, the direct sound is localized forward. Also, the reflected sound signal F to be emitted at the front left and right positions
Since L and FR are reproduced from the front left and right positions as they are,
The sound is localized in the front and a sound field feeling is obtained in the front. Also, the reflected sound signal RL + RR to be emitted at the rear is reproduced from the left and right positions as two reflected sound signals R _{+ 90} and R- ₉₀ having _phases opposite to each other. Is obtained,
As a result, a sound field feeling up to the rear can be obtained with only the front two-channel speakers 28 and 30.

When the sound is reproduced by the four-channel speakers 28, 30, 32, and 34 (FIG. 1) of the front left and right and the rear left and right, the rear left and right reflected sound output from the reflected sound signal generating means 48 in FIG. The signals RL and RR are individually guided to the output terminals of the rear left and right channels via the power amplifier without being combined.

In the above embodiment, the same sound field is given to simultaneously-produced music and sound effects. However, a sound field is given only to a specific sound (for example, a sound effect), or a reflected sound signal generating means. By providing a plurality of, it is possible to provide different sound fields for music and sound effects, or to provide different sound fields for each sound effect.
