PURPOSE:To make overtone relation clear and facilitate interpolation by controlling one spectrum as analysis data of one band-pass filter even when the spectrum extends over plural filtering band or move between plural band-pass filter with time. CONSTITUTION:A sound source has an analysis part 1, a storage part 2, an interpolation part 3, a shift part 4, and a composition part 5. Musical sound waveform data are stored analytic parameters (frequency data and intensity data) by spectra (band-pass filter). When the musical sound waveform data are put together again, those analytic parameters are put together. When one spectrum is detected by plural band-pass filters, intensity data detected by all band-pass filters are concentrated on intensity data of one band-pass filter and when one spectrum moves between plural filtering bands according to the progress of the musical sound waveform data, it is traced by one band-pass filter. |
