i know i can easily speed up a sound file’s playback by altering the
playback speed in sfplay objects etc. and other software does things
like time stretch/compress with pitch correction. my question: is
there something out there for maxmsp that would enable us to make a
soundfile play progressively faster but doesn’t raise the pitch?
again, the first part can be done with a ramp to the speed input on a
groove object, but what about pitch correction?
alternatively, is there other software out there that can do a dynamic
real time speed increase/decrease with pitch kept stable?
For external software you might wanna try SoundHack (free). You can
draw Graphs for speed or pitch change and then save output to a new
soundfile if you want to.
Or if you really need the real time thing try ableton live – though not
