Title:
DEVICE AND METHOD FOR PROCESSING WAVEFORM DATA
Document Type and Number:
Japanese Patent JP3714397
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To avoid pitch variation when reading independent plural waveform data at the same rate.
SOLUTION: Waveform memory is storing attack waveform data and loop waveform data read out successively. A pitch AP at the time of reproducing the attack waveform is calculated by the processing of steps 206-222. A pitch LWP at the time of reproducing the attack waveform data is calculated by the processing of steps 224-228. The attack waveform data are re-sampled according to the ratios of AR to LWP AP/LWP by the processing of steps 230-236, and are rewritten to attack waveform data re-sampled from the original attack waveform data. Thus, pitch variation can be avoided even if the attack waveform data and the loop waveform data are continuously read out at the same rate.
