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, crazy sonic experimentation, or just listening to your music library in a new way.
Before you buy AudioStretch, consider first downloading AudioStretch Lite for FREE. Apart from some feature limitations, it's the same as the full (paid) version. The Lite version is a great way to see whether AudioStretch works well for you. And if the Lite feature set is sufficient for you, you'll save yourself some cash too.
