Title: Method and apparatus for shifting pitch of acoustic signals
Inventor: KUMAMOTO YOSHINORI
IPC: G10L21/013
Filed: 2001-09-06
Granted: 2003-03-21
Abstract: A method for shifting a pitch of acoustic signals, which are expressed in terms of a series of digital signals, to an optional pitch, uses a compacting and/or expanding process on the time axis and cross-fades a fade-in acoustic signal, stored in a memory with a fade-out acoustic signal, also stored in memory. The compaction and/or expansion of the time axes minimizes phase differences between the fade-in and fade-out acoustic signals to minimize tremolo in the output signal. The reduction in phase difference employs fundamental tones of the two series of signals selected by low-pass filtering the acoustic signal. One embodiment performs two-step compensation with a rough compensation using blocks of the digital signals and a fine compensation using samples from blocks.
