PROBLEM TO BE SOLVED: To reduce the data volume of audio data. SOLUTION: Environment data L1, L2 indicating environmental conditions are stored in the first area A of plural storage areas 20 formed in a buffer memory and waveform data S indicating sound are stored in the second area B. The data L1 indicate the state of a sound field of a virtual sound source and the data L2 indicate the position of the virtual sound source. Since plural environmental data L1, L2 are allowed to correspond to one waveform data S, the data volume of audio data can be reduced. |
