Patent ID: 6873955

Claim:
A waveform recording method comprising the steps of: supplying waveform data; extracting, from the waveform data supplied by said step of supplying, sample data of a timbre factor indicative of a waveform shape; storing, into a memory, the sample data of the timbre factor, extracted by said step of extracting, along with first time position information based on an extracted position, on a time axis, of the sample data of the timbre factor; extracting, from the supplied waveform data, sample data of a pitch factor indicative of a pitch characteristic or sample data of an amplitude factor indicative of an amplitude characteristic; and storing, into the memory, the sample data of the pitch factor or amplitude factor, extracted by said step of extracting, along with second time position information based on an extracted position, on a time axis, of the sample data of the pitch factor or amplitude factor.
