AudioStretch Lite

Change the speed of audio files without changing the pitch. Listen as you drag the waveform. Play at zero speed. Transpose your music. Loop. All in an incredibly responsive and easy-to-use app. Ideal for transcription, learning songs by ear, or just listening to your music library in a new way.

If you run into any problems with AudioStretch Lite, please contact support@audiostretch.com. Posting a negative review won't help, as I can't contact you for details.

Note that this is the free, Lite edition of AudioStretch, which has a few feature limitations. To get all the features, without the limitations, consider buying the Full version.
