Does anyone know of a Python module for *moderate* "time-stretching"[1] an MP3 (or AIFF) file?
FWIW, the audio I want to time-stretch is human speech. TIA! ~K [1] By "moderate time stretching" I mean, for example, taking an audio that would normally play in 5 seconds, and stretch it so that it plays in 7.5 seconds, keeping the pitch unchanged. A lot of software out there does this badly; e.g. the time-stretched audio springs extraneous "beats" of intensity that are very obtrusive and annoying; I guess it's some weird wave self-interference effect. Also, I stress *moderate* time stretching to explicitly rule out the extreme (~50X) time-stretching that software like PaulStretch is designed to accomplish. -- http://mail.python.org/mailman/listinfo/python-list
