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.
As a musician one of the most helpful tools you can have is the ability to slow-down, loop or auto-transpose the notes for a piece of music you are trying to learn.
AudioStretch is the world’s first audio and video transcription tool.
Now you can manipulate the pitch, speed and transcribe your tunes from both audio and video files; or by using your phone’s camera you can capture video directly into AudioStretch and transcribe it!
• Import audio or video files
• Capture video with your phone camera for transcription
• Change the speed of files without changing the pitch
• Listen to the individual notes as you drag the waveform
• Play audio and video at zero speed
• Transpose any music
• Loop difficult to learn sections
With AudioStretch you get all of this 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.
• Load songs from your Music Library. (Note: songs from Apple Music have DRM and therefore cannot be loaded).
• Document Picker import/export option supports iCloud, OneDrive, and more
• Open Dropbox files and email attachments via "Open In"
• LiveScrub™ : listen as you drag/hold the waveform
• Speed range -10x to 10x, including zero speed!
• Instant freeze to zero speed by double-tapping on speed display
• Pitch shift range +/- 36 semitones
• Keyboard/spectrum feature for transcription

I'm a veteran of Anytune Pro+ and will doubtless continue to use that app a great deal, not least for ReFrame isolation, but this app certainly adds superb functionality which cannot be found elsewhere
The 'zero speed' playback is a brilliant feature, as is the unique keyboard display of the frequency spectrum. As others have mentioned, the scrubbing is uncannily smooth and thus more usable than any other such feature I have encountered. I'm delighted to have found this, for all that I evidently overlooked its existence for years...

Great for transcribing complex solos
I was looking for an app which had the key features from a PC program “Transcribe!”, namely a playable piano keyboard with mapped spectral analysis. This is the only app I’ve found which does this.
I downloaded demo versions of about six different music-orientated transcription apps to try out and this is the one I ended up buying. The interface is easy to navigate with a nice big waveform display and a “thumbnail” version to jump to other parts of the track.
This one goes down to 0.01 speed and has fine pitch tuning. The ability to hear portions when paused and to “play” the waveform by scrubbing one’s finger are fantastically useful.
It would be nice if the waveform had pinch zoom. Would also be good if it were able to be used in landscape orientation as the waveform and keyboard would have more screen space.
This doesn’t have a few of the features from another app I found, namely the ability to add a delay between pressing play and the audio starting, or the option to add a pause between instances of the loop. There isn’t any EQing. That aside, it ticks all the boxes and is well worth the money and much better value than other apps at the same (or higher) price.

Hi Quatschmacher - Thank you for the feedback. We appreciate it. We will forward your feedback on the features mentioned to our engineers for future consideration. Cheers!
Almost PERFECT transcription app
Great work guys it’s well thought out by musicians for musicians !
Please can you make rewind customisable and 15s is way too much 5s or 3s would be more useful and it would be even better if you make adjustable in the settings?
