Abstract

Disclosed is a sound generation device including a receiver which receives a sound emission instructing signal in which time data is included and a difference calculator which calculates a difference between a timing indicated in the received time data and a timing when the sound emission instructing signal is received by the receiver, when the sound emission instructing signal in which the time data is included is received. The sound generation device further includes a histogram creator which creates a histogram on the basis of the calculated difference and a difference calculated previously, when the difference is calculated and a timing controller which controls a timing for supplying the received sound emission instructing signal to a sound emission unit on the basis of the calculated difference and a most frequent difference in the created histogram, when the difference is calculated.

Claims

1. A sound generation device, comprising:

a receiver which receives a sound emission instructing signal which includes time data;

a difference calculator which calculates a difference between a timing indicated in the received time data and a timing when the receiver receives the sound emission instructing signal, when the sound emission instructing signal is received;

a histogram creator which creates a histogram on the basis of the calculated difference and a difference calculated previously, when the difference is calculated; and

a timing controller which controls a timing for supplying the received sound emission instructing signal to a sound emission unit which is connected to the timing controller on the basis of the calculated difference and a most frequent difference in the created histogram, when the difference is calculated.

2. The sound generation device according to claim 1 further comprising a performance operator which is held by a performer,

wherein

the performance operator comprises:

a movement detection unit which detects a movement of a main body of the performance operator,

a sound emission instruction generator which generates the sound emission instructing signal on the basis of the movement of the performance operator which is detected by the movement detecting unit, the sound emission instructing signal giving an instruction to emit a sound to the sound emission unit, and

a transmitter which sends the sound emission instructing signal generated by the sound emission instruction generator with time data indicating a timing of transmission included in the sound emission instructing signal.

3. The sound generation device according to claim 1, wherein

the timing controller determines whether the calculated difference is greater than the most frequent difference,

when the calculated difference is determined as being greater than the most frequent difference, the timing controller supplies the received sound emission instructing signal to the sound emission unit immediately, and

when the calculated difference is not determined as being greater than the most frequent difference, the timing controller sends the received sound emission instructing signal to the sound emission unit at a timing obtained by adding the most frequent difference to the timing when the sound emission instructing signal is received.

4. A sound generation method, comprising:

receiving a sound emission instructing signal which includes time data;

calculating a difference between a timing indicated in the received time data and a timing when the sound emission instructing signal is received, when the sound emission instructing signal is received;

creating a histogram on the basis of the calculated difference and a difference calculated previously, when the difference is calculated; and

controlling a timing for supplying the received sound emission instructing signal to a sound emission unit on the basis of the calculated difference and a most frequent difference in the created histogram, when the difference is calculated.

5. A sound generation method according to claim 4, wherein;

determining whether the calculated difference is greater than the most frequent difference,

supplying the received sound emission instructing signal to the sound emission unit immediately, when the calculated difference is determined as being greater than the most frequent difference, and

sending the received sound emission instructing signal to the sound emission unit at a timing obtained by adding the most frequent difference to the timing when the sound emission instructing signal is received, when the calculated difference is not determined as being greater than the most frequent difference.

6. A computer readable medium having stored a computer-executable program, the program comprising:

operational instructions that cause the computer to receive a sound emission instructing signal which includes time data;

operational instructions that cause the computer to calculate a difference between a timing indicated in the received time data and a timing when the sound emission instructing signal is received, when the sound emission instructing signal is received;

operational instructions that cause the computer to create a histogram on the basis of the calculated difference and a difference calculated previously, when the difference is calculated; and

operational instructions that cause the computer to control a timing for supplying the received sound emission instructing signal to a sound emission unit the basis of the calculated difference and a most frequent difference in the created histogram when the difference is calculated.

7. The computer readable storage medium according to claim 6, the program comprising:

operational instructions that cause a computer to determine whether the calculated difference is greater than the most frequent difference,

operational instructions that cause a computer for supplying the received sound emission instructing signal to the sound emission unit immediately, when the calculated difference is determined as being greater than the most frequent difference, and

operational instructions that cause a computer to send the received sound emission instructing signal to the sound emission unit at a timing obtained by adding the most frequent difference to the timing when the sound emission instructing signal is received, when the calculated difference is not determined as being greater than the most frequent difference.
