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.

• 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 love the app there's alot of stuff to do on it. The only thing that's atleast I'm having an issue with is the in-app purchase for more pitch and speed. Because everytime I open the app and try to speed up or change the pitch for the audio it says I need to purchase it again! I don't know if it's a bug or glitch but whatever the deal is please fix it! Let's be honest I'm not paying another $10.00 dollars again for something I already purchased.

Very excellent quality result. Features scroll through map of audio that plays back on the timeline. Can change pitch and tempo (speed by changing both these options). Paulstretch type algorhythm which realistically paints the missing audio data. No more PC Paulstretch w/ eq filters, samples made in ten seconds. 1 negative: android scoped storage does not allow save to device; user must export audio by uploading large file size to "cloud" or "drive" when option to save to device should exist.

Pretty ok. Getting the Pro version isn't hard but it doesn't offer much more. Using the app on Android and I've seen people can import videos and make audios off of that. Kinda pressed that the feature isn't for Android. It just seems unfair, especially since some can't afford an iPhone. That's why I'm giving the app 2 stars and not 3 or 4. I will update if the feature gets added to Android.

Sorry for the frustration. Unfortunately, video support isn't available on Android devices at the moment. So sorry about that. We'll let the developers know about this, and thank you for understanding.
