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.

I bought this app and love it, best tool I've encountered for music transcription. I would give 5 star but recently I'm getting a bug that prompts me to purchase the app when I'm using it offline usually pausing whatever I'm listening to, it's pretty annoying since I've bought the app and don't want to be bothered with this in the middle of my practice Please fix ♥️

fell off significantly after the BandLab integration because BandLab's pitch and tempo editing is not nearly as good as it was before

I love looping video game music and playing it with this app, it's super simple and I highly recommend it. However, since getting it on my new phone, it limits my options to 1.50x speed and 3 pitches even after I have BandLab installed. and instead of unlocking the 10x speed and 36 pitch, it still tells me to either buy the Pro version or install BandLab, which I already have, and just sends me to BandLab, which stops playing when I leave the app. I'd appreciate if this issue was fixed.
