I am looking for a good program that can alter the speed of any audio file without changing its pitch.
I remember that about 2 years ago I downloaded for trial MuvAudio and I saw that - in addition to converting audio files - it could altering the speed of audio files as well (without altering it's pitch). However, now I read in the Web about the functions of MuvAudio, and I don't see there such function.
Could one tel me whether the current MuvAudio still includes such a function and, in any case, which program would be the best for that purpose.
Thanks in advance
