I'm looking for a software that reproduces audio files (wav and mp3 if possible) and provides a way to change the playback speed in real-time, flawlessy. I mean, without any gap, pop, or noise. Like the sampling clock is changed smoothly.I'm NOT interested in maintaining the pitch constant (like this question: Play a sound file slower or faster). Instead the pitch MUST follow the new speed.I need to change the speed programmatically, say from 20% to 200% of the original one.Is there something ready, without reinventing the wheel?
Programmatically change the playback speed (NOT pitch) in real-time
