Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game device that plays sound such as sound effects or BGM related to the contents of a game for the purpose of enhancing the sense of reality during the game.

[0002]

2. Description of the Related Art In recent game machines, particularly game machines such as a car racing game, a fighting game, a shooting game, and a role playing game, a very realistic image expression has become possible. In a game device that displays a real image, a real sound that matches the image is also required. In such a game device, when a player selects a course (eg, in a car racing game) or an opponent (eg, in a fighting game) that the player wants to play before starting the game, an appropriate sound is selected in accordance with the selection. And BGM are selected on the game device side.

[0003] In addition to games that sell real images, for example, in puzzle games called “falling things,” sound effects and sound and BGM along with the contents of the puzzle that characterize the characters appearing are played. ing.

[0004]

By the way, the creator of a game uses a composition, a selection of music, and a created voice or BGM based on his own feelings and judgments, but these may not match the player's preference. . For this reason, if a plurality of voices and BGM are prepared in advance, and the player can freely select his or her favorite voice or BGM, the fun of the game is increased and the repeatability is improved.

[0005] Further, in the conventional game apparatus, once the game is started, the player cannot switch between voice and BGM during the game. But,
Even in the middle of the game, voice or B
If the GM can be switched, the fun of the game is further increased.

Further, for example, depending on the surrounding environment in which the game device is placed, voices or BGM prepared in advance may be used.
May be difficult to hear. For example, when there is a relatively low-pitched noise source in the surroundings, it is difficult to hear the low-pitched portion of the game sound. In such a case, if it is possible to switch to a predominantly prepared treble-based sound or BGM, it is less likely to be affected by the surrounding noise situation. In addition, when a person who has difficulty hearing high sounds due to hearing impairment or who has difficulty hearing low sounds plays a game, if it is possible to switch between sounds mainly composed of high sounds and sounds mainly composed of low sounds, it is very convenient.

[0007] The present invention has been made in view of such a technical background, and the player can select his preferred voice and B

Embodiments of the present invention will be described below with reference to the drawings. In each of the drawings showing each of the following embodiments, among the reference numerals indicating the respective units and data of the device, those having the same last two digits of the numbers represent the same or corresponding ones. .

[Embodiment 1] FIG. 1 is a block diagram showing only a portion for reproducing audio data in a game device according to Embodiment 1.

In FIG. 1, a ROM 113 stores a sequence data 113a and a waveform data ROM 116 to be described later.
Table 11 of waveform data stored in the memory
3b is stored. Here, the sequence data 11
3a is like design data for generating an actual sound using the waveform data (data obtained by sampling the actual sound) stored in the waveform data ROM 116. It contains information about timing, volume, which tone to use, and sound effects such as reverb, vibrato, and echo. This sequence data is also called "score data".

An address table 11 for the waveform data
In the address data included in 3b, a starting address, an ending address of each waveform data, and a loop address indicating where to loop when audio is looped and reproduced are set.

It is of course possible to store the sequence data 113a and the address table 113b in separate memories.

Sequencer 112 interprets sequence data 113a stored in ROM 113, and sends predetermined instruction data and address data of waveform data ROM 116 to PCM tone generator 114 in accordance with the interpreted contents. When receiving the instruction data from the sequencer 112 and the data of the waveform data address table 113b stored in the ROM 113, the PCM sound source 114 first receives
The address of the required waveform data is given to the waveform data ROM 116 via the address bus 115, and the waveform data stored in the waveform data ROM 116 is read via the data bus 117. Then, the read data is processed based on the above-mentioned instruction data, and is output as actual audio data.

The waveform data ROM 116 stores a large number of waveform data. Here, each waveform data is expressed as WAVE1a or the like. In the present embodiment, as shown in FIG. 1, a set of waveform data suffixed with an alphabet “a” (hereinafter referred to as “a set”) and a set of waveform data suffixed with an alphabet “b” (hereinafter “a set”) b) is prepared. Each of the sets a and b corresponds to the “waveform data group” described in the claims. That is, a set of waveform data WAVE0a, WAVE1a,...
The set of AVE1b,... Is a set of b waveform data sets,
A large number of waveform data are included in each of the group of waveform data and the group b of waveform data. This is the same in the following embodiments. In the present embodiment, the two sets of waveform data are stored in one waveform data ROM 116. The waveform data ROM 116 shown in FIG.
0a, WAVE1a,..., WAVE0b, WAVE1
The waveform data are shown in the order of b,..., but the addresses of the waveform data stored in the waveform data ROM 116 are not necessarily WAVE0a, WAVE1a,.
It is not necessary that the order is VE0b, WAVE1b,...

In the waveform data of group a and the waveform data of group b, the waveform data having the same number after "WAVE", for example, WAVE0a and WAVE0b are corresponding data.
The data amounts of both are set to be the same. Also, for example, a set of n-th waveform data WAVEna
Is the waveform data of the engine sound of the car played in a certain scene of the game, and the b-th set of the n-th waveform data WA
VEnb is also sound corresponding to each other, such as waveform data of an engine sound played in the same scene. However, the contents of the sounds are different, for example, one is a sports car engine sound and the other is a jeep engine sound.

Next, the operation of the apparatus shown in FIG. 1 will be described. Here, it is assumed that the game device has been set in advance to reproduce the sound based on the waveform data of group a. If the player wants to switch the audio after the game starts, switch 110
push. When the switch 110 is pressed, the input device 111
Detects this, and issues an instruction to that effect to the sequencer 112. In response to this instruction, the sequencer checks the waveform data to be changed, and reads the address data of the waveform data from the waveform data address table 113b.

PCM sound source 11 which is a general PCM sound source
In No. 4, since the waveform data cannot be reproduced from the middle, even if the switch 110 is pressed during the reproduction of a certain waveform data, the sound is not switched until the reproduction of the waveform data is completed. For example, the waveform data being reproduced at the time when the switch 110 is pressed is set to WAVE of a set.
Assuming that it is ma, the sound switching is not performed until the reproduction of the WAVEma ends, and reading and reproduction of the WAVEma continue until this data ends. When the waveform data WAVEma reaches the end, the sequencer 11
2 sets the start address of the waveform data address of the b sets of waveform data WAVE (m + 1) b in the PCM tone generator 114 in order to switch the voice. PCM sound source 1
When the head address of the waveform data address is set to 14, address data of successive addresses are generated from that point on, and this is sequentially applied to the waveform data ROM 116 of the address to read out the waveform data one after another. Playback is performed in real time.

When preparing waveform data, it is common to use a series of sounds as one waveform data. Therefore, as described above, the fact that another waveform data is not reproduced during the reproduction of waveform data is as follows. This also means that the sound is not switched where the separation is bad, which is an advantage that the sound is switched naturally. However, the time length of the waveform data can be freely set when preparing the waveform data. Therefore, if a large number of short-time waveform data are prepared, the time from when the switch 110 is pressed to when the sound is switched is reduced. Can be shorter.

When the player wants to switch the sound on the way after the game starts, the sound prepared in advance does not match the player's taste, the noise is set in advance, or the sound is prepared in advance by the auditory characteristics of the player. There may be a case where the reproduced voice is difficult to hear. Further, even if the games have the same content, different sounds change the atmosphere of the game. Therefore, if a large number of sounds are prepared, the likelihood of the same player playing repeatedly increases, and the repeatability is improved.

In this embodiment, the waveform data group is represented by a
Although there are two sets of the set and the b set, the number of waveform data groups is not limited to this, and may be three or more sets. In this case, for example, each time the player presses the switch 110, the set may be sequentially switched to the next set, or the same number of push buttons as the prepared set may be provided, and the desired waveform data of the desired set may be determined depending on which one is pressed. A set may be selected.

[Second Embodiment] FIG. 2 is a block diagram showing only a portion for reproducing audio data in a game device according to a second embodiment. In FIG. 2, each part is indicated by reference numerals in the 200's, and the last two digits of the numerals are the same as the last two digits of the reference numerals in FIG. 1 related to the first embodiment. Here, the configuration and function unique to the game device according to the second embodiment will be mainly described, and the description of the portion having the same configuration and function as the first embodiment will be omitted.

In the apparatus shown in FIG.
Whereas the apparatus shown in FIG. 2 is provided with two waveform data ROMs 216a and 216b each having its own address space. The selector 220 provided after the input device 211
A select signal is issued to one of these two waveform data ROMs 216a and 216b to make them active. P
Address data given from the CM tone generator 214 is supplied to each waveform data ROM via data buses 215a and 215b.
The same address data is provided to 216a and 216b. On the other hand, even if the address data is supplied, the waveform data ROMs 216a and 216b do not read the waveform data unless the selector 220 receives the select signal. That is, only the waveform data ROM to which the address data is supplied and to which the select signal is supplied reads the waveform data, and the data bus 217a or 217
This is given to the PCM sound source 214 via b.

There are the following rules for storing data in the waveform data ROMs 216a and 216b. That is, for example, from address 0 of the waveform data ROM 216a to 10
When the waveform data WAVE0a of the engine sound of a certain car is stored between addresses 00, the waveform data RO
The waveform data ROMs 216a and 216 store the waveform data WAVE0b of the engine sound of another automobile between addresses 0 and 1000 of M216b.
At the same address of b, the corresponding audio waveform data is
The data length and the sampling frequency are stored in the same manner.

In the first embodiment, the sets of waveform data a and b are stored at different addresses of the same waveform data ROM even if they correspond to each other. PC
Since the address data that can be generated by the M tone generator 114 cannot be changed until reading and reproduction of one waveform data is completed, one set of the other data is not read until the reading and reproduction of certain waveform data is completed. Could not be read and reproduced.

On the other hand, in this embodiment, two waveform data ROMs having the same address space are provided (216a
216b) and the respective address buses 215
Since the common address data is always given using a and 215b, even while reading and reproduction of one waveform data is being performed, the selector 220 outputs
By issuing a select signal indicating which waveform data ROM is to be selected, the active waveform data ROM can be easily switched from one to the other. Therefore, immediately after the player presses the switch 210, the sound of the waveform data of the group a (group b) is changed to the group b (a).
Set) can be easily switched to the sound of the corresponding waveform data.

As described above, according to the game apparatus according to the second embodiment, after the game has started, the player can switch the voice according to his / her preference, the surrounding noise, or the player's noise. The point that you can switch to sounds that are easy to hear when the sounds prepared in advance are difficult to hear due to hearing characteristics, and that you can enjoy the same game with different sounds, etc.
Same as the first embodiment, but further has a feature that the player can switch at the moment when he wants to switch the sound.

Although two waveform data ROMs are provided in the present embodiment, three or more waveform data ROMs may be provided to prepare corresponding waveform data groups. Same as in the first embodiment.

[Third Embodiment] FIG. 3 is a block diagram showing only a portion for reproducing audio data in a game device according to a third embodiment. In FIG. 3, each part is indicated by reference numerals in the 300's, and those whose lower two digits are the same as the lower two digits in the figures related to Embodiment 1 or Embodiment 2 are those corresponding to each other. Represent. Here, mainly the third embodiment
Of the game apparatus according to the present invention, and description of portions having the same structure and function as those of the first and second embodiments will be omitted.

As shown in FIG. 3, in this embodiment, the PC
It is characterized in that an address conversion circuit 330 is provided in the middle of an address bus 315 from the M sound source 314 to the waveform data ROM 316. Also in the present embodiment, the switch 310
Is the same as the second embodiment in that the address data output from the PCM sound source 314 does not change even if is pressed. However, in this embodiment, when the switch 310 is pressed, a signal to that effect is sent from the input device 311 to the address conversion circuit 33.
0 is given. Upon receiving this signal, the address conversion circuit 330 converts the address data provided from the PCM sound source 314 into a predetermined value and converts the address data into a predetermined value.
Give to.

As in the first embodiment, two waveform data groups (set a and set b) are stored in one waveform data ROM 316. The point that the corresponding waveform data of each set has the same data length and sampling frequency is the same as the first and second embodiments.

In addition, the waveform data ROM 31 shown in FIG.
6 has a certain offset in the address value of the corresponding waveform data of each set. For example, the start address of waveform data WAVE0a of group a is “0”.
Address ", b sets of corresponding waveform data WAVE0b
Is "10000", and waveform data W of group a is
When the head address of the AVE1a is "1000", the address value of the waveform data of the b group is "11000", such that the head address of the b group of waveform data WAVE1b is "11000".
For the address value of the corresponding waveform data of group a, “10
000 ".

The value of the offset corresponds to the size of the address value converted by the address conversion circuit 330.
That is, assuming that the reading and reproducing of the waveform data of the set a are performed first, the player presses the switch 310 at this time, and when a switching signal to that effect is given from the input device 311 to the address conversion circuit 310, the address conversion The circuit 310 provides the waveform data ROM 316 with new address data obtained by adding an offset value of “10000” to the address data supplied from the PCM sound source 314. Then, from that point on, the waveform data read from the waveform data ROM 316 is switched from the set of waveform data a to the set of waveform data b, and thus the reproduced voice is also switched.

In the device of the present embodiment, similarly to the device of the second embodiment, the switching signal is sent from the input device 311 to the address conversion circuit 330 even during the reading and reproduction of one waveform data. Immediately after the player presses the switch 310, group a (group b)
It is possible to easily switch from the sound of the waveform data having a waveform to the sound of the corresponding waveform data of group b (group a).

In addition, when the address conversion circuit 330 is provided as in the present embodiment, a plurality of waveform data ROMs are not required unlike the second embodiment. As long as the total capacity of the ROMs is the same, the cost can be reduced by reducing the number of ROMs. Therefore, with the configuration as in the present embodiment,
This is more cost effective than the second embodiment. Also,
The address conversion circuit 330 can be built in the same integrated circuit as the PCM tone generator 314. In such a case, it is not necessary to provide an extra integrated circuit. Does not cause

As another mode of the address conversion operation of the address conversion circuit 330, instead of giving a regularity such as an offset to the address data of the corresponding waveform data of each set, the address of the corresponding waveform data of each set is assigned. A table linked to each other (hereinafter referred to as an “address correspondence table”) is prepared, and when a switching signal is given from the input device 311 to the address conversion circuit 310, the address conversion circuit 310 refers to the address correspondence table and Look up the address and store it in the waveform data ROM 316.
You can also give to.

The adoption of the address conversion operation using the address correspondence table as described above is very advantageous when, for example, two sets of waveform data are almost the same, but only some of them are different. In other words, if only one waveform data common to the two sets is prepared, and only different waveform data is separately prepared for each set, the effect may be described in the address correspondence table,
In this way, the capacity of the waveform data ROM 316 can be efficiently used without waste.

As described above, the game device according to the present embodiment is characterized in that the player can switch the voice according to his / her preference after the game starts, due to ambient noise, or due to the auditory characteristics of the player. It is said that you can switch to sounds that are easy to hear when the prepared sounds are difficult to hear, you can enjoy the same game with different sounds, and you can switch to the moment the player wants to switch sounds Regarding the point, Embodiment 1 or Embodiment 2
Is the same as In the present embodiment, there is an additional effect that the required capacity of the waveform data ROM can be reduced and the capacity of the waveform data ROM can be efficiently used without waste.

In this embodiment, only two sets of waveform data groups are provided. However, three or more waveform data groups can be provided as in the above-described embodiments.

[Fourth Embodiment] FIG. 4 shows the calculation of the proportion of the waveform data currently read out by the game device according to the fourth embodiment, of the portion that has been read out.
9 illustrates a method of determining which address of the corresponding waveform data should be read after the switching. The hardware configuration of the present embodiment is the same as that of the first embodiment shown in FIG.
Since the hardware configuration is substantially the same as that of FIG. 1, the illustration is omitted here, and when referring to the hardware, FIG. 1 is referred to. The difference from the first embodiment is that the PCM sound source of the present embodiment has a specific function described later added to the PCM sound source 114 of FIG.

In each of the above embodiments, two sets of corresponding waveform data have the same data length and the same sampling frequency. On the other hand, in the present embodiment, a case where the data lengths of two sets of corresponding waveform data are different is handled. However, it is assumed that the data corresponding to each other has the same reproduction time. As the form in which the reproduction time is the same and the data length is different, it is conceivable that the sampling frequency of the corresponding waveform data is different or the data width (8 bits, 16 bits, etc.) is different.
For example, if one of the two waveform data groups is mainly composed of a high tone (high frequency) and the other waveform data group is mainly composed of a low tone (low frequency), Even if the reproduction time is the same, the latter waveform data can reduce the sampling frequency, and the data amount can be reduced accordingly.

Even in such a case, the apparatus of the present embodiment can switch the sound between different sets of corresponding waveform data at an arbitrary timing. As described above, since a general PCM sound source is used in the first embodiment, it is necessary to switch a set and reproduce another set of corresponding waveform data from the middle while certain waveform data is being read. Could not. However, since the PCM tone generator generates the address of the waveform data ROM by itself, if a simple circuit for extracting the address data from the PCM tone generator is added, another set of corresponding sets based on the extracted address data is provided. It is possible to calculate from which address the waveform data should be reproduced.

Therefore, in the present embodiment, when reading a certain set of waveform data, it is always calculated what percentage of the entire waveform data has been read at the present time. Then, with respect to the other set of corresponding waveform data, the same percentage of the address is indicated by a pointer.

For example, in FIG. 4, a set of waveform data W
Assuming that AVE0a has been read and 75% of the data has been read at the present time, the pointer 401 points to 75% of all addresses of the b sets of corresponding waveform data WAVE0b. Conversely, b sets of waveform data WAVE0b are currently being read, and
Assuming that the reading of% has been completed, the pointer 400 points to 75% of all the addresses with respect to the set of corresponding waveform data WAVE0a. And
When the switch 110 is pressed by the player while one set of waveform data is being read, reading of the corresponding set of waveform data from the other set is started from the address pointed to by the pointer. . In this way, even when the sampling frequencies of the corresponding waveform data are different from each other, it is possible to smoothly switch the sound without giving an unnatural feeling.

[0049]

As described above, according to the present invention,
At any time during the execution of the game, the player can freely switch sounds such as sound effects and BGM according to his / her own preference, thereby increasing the fun of the game.
When it is difficult to hear a prepared sound effect or the like due to the surrounding noise situation or the state of hearing of the player, it is possible to switch to an optimum sound effect or BGM that is easy to hear at an arbitrary timing.
