Abstract:
A system for rendition control, the system comprising:a waveform storage means for storing a continuous sound waveform;a compression and expansion means for generating a reproduction waveform by compressing or expanding the sound waveform while following a temporally changing control signal indicating a level of compression or expansion; anda periodic signal generation means for generating a periodic signal whose waveform shape changes with the passage of time;wherein the periodic signal is communicated to the compression and expansion means as the control signal; andwherein the periodic signal generation means comprises:a periodic waveform storage means for storing a plurality of periodic waveforms;a periodic waveform read-out means for temporally switching, in accordance with certain sequence information, between the plurality of periodic waveforms so as to generate a periodic signal whose waveform shape changes with the passage of time; anda sequence information storage means for storing sequence information specifying an order with which the periodic waveforms are read out by the periodic waveform read-out means.
