About this app

As a musician, or someone who is started learning music, one of the most helpful tools you can have is the ability to slow-down, loop or change pitch for a piece of music you are trying to learn.

With the award-winning AudioStretch app you can change the speed of an audio file without affecting the pitch, or change the pitch without changing the speed. With its unique LiveScrub™ feature, you can even play audio as you drag the waveform so you can listen note-by-note.

AudioStretch is incredibly responsive and easy-to-use. Ideal for transcription, learning songs by ear, crazy sonic experimentation, or just listening to your music library in a new way.

FEATURES:
• Real-time pitch shifting by up to 36 semitones up or down, with fine tuning to 1-cent resolution
• Real-time speed adjustment from zero speed up to 10x normal speed
• Zero-Speed playback - set the speed to 0 or simply tap and hold waveform to listen to the specific note
• LiveScrub™ - listen as you drag/hold the waveform
• Import audio files from your music library, device storage or cloud storage like Google Drive, Dropbox, OneDrive etc
• Export with pitch and/or speed adjustment into an audio file and save it to your device storage or share it to cloud storage.
• Capture audio with your phone’s default audio recorder (if installed).
• Markers - set an unlimited numbers of markers to quickly jump between important parts of the piece or simply bookmark particular area.
• Flexible A-B loop allows practicing a particular area of the piece you’re learning in a most comfortable way.
• No annoying ads 👍

Please note that the video playback feature is not available on the Android (both free and paid) version of AudioStretch.

Ratings and reviews

Seems like the developer stopped trying to charge for features that were already free and gave the app a face lift, so my rating is back up. However, a feature I still want to see is the ability to select songs that I've already imported from a list. I know I can scroll through my files every time to get the same one, but that's quite tedious. Edit: quick developer response = 5 stars

It's a great app overall. But there are two problems I'm currently having with the app. 1. If you play the video backwards too fast the video gets choppy. And 2. it randomly freezes when you go back and forth too fast. These problems never occurred in the old version of the app till this current version of the app so it be nice if you guys would fix these bugs please and thank you

Almost perfect. I like the detailed loudness view, you can scroll it and pause it quickly from that graphic, A-B, Pitch Shift, Tuning Adjust all there. Imports fine. You'd get one more star if you made it easier to go back and forward through recently used songs. Would also be lovely if one could assign a Bluetooth control to back up a specified amount rather than just use finger, arrows, or A-B. Learning a tune by ear has a lot in common with secretarial transcription hardware/software. Fair $.
