Audio Speed Changer Lite

Audio Speed Changer Lite lets you adjust tempo and pitch in real time. Select an audio file, mark a region to play (and loop), and change speed and pitch on the fly. Export your edited audio when you're done. The app is optimized for iPad performance.

Key features include independent pitch and tempo control, region looping, region selection, and support for multiple formats (mp3, wav, m4a, ogg, aac, and more). You can export to wav or mp3, boost volume, apply voice reduction, and play left/right channels separately. Dropbox import and emailing files are available. Note that extreme pitch/tempo changes can introduce noise, and voice reduction quality depends on input.
