MP3 editing
 

Im looking for a good sound editing program that will allow time stretching aswell as all the usual cut copy paste without resampling an mp3?

Any suggestions would be gr8

Garageband or Audacity.

Edit mp3s without resampling using Fission.

Though time stretching can never be done without resampling.

I'm using Amadeus Pro for all kind of music editing. It also has multiple track support and fading/panning automation lines. Here are four demos to show the time streching function. The second tune has a 8 step tone plus and 75% speed, the third one 5- tune and 150% speed adjust. Number 4 has a speed change from 75 - 100 - 140%, but no tone adjust.

thanks for the suggestions will look into them i know couldnt get to grips with audicy

Soundtrack Pro ?
