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!

Ratings and Reviews
Very nice but needs a “recents” section in the open dialog
This is *almost* the slow downer I’ve been looking for! Great clean interface (i really don’t know why most are so incredibly ugly) and it can read from the local library and my cloud services.
The one thing that seems obvious and is missing is a “recent items” section in the file open dialog. I tend to be working on a few songs at once, so why not have the top item on the + menu be “recents >” that opens up a submenu list of the last twenty files, sortable by most recent or name, and then opens them with their last pitch/time settings, markers, and loop. Then it would be perfect!
Will be upgrading to the full version, because i need more than three minutes & three semitones :)

Hi huzzam - Thank you so much for the kind words and sharing your feedback! We'll definitely consider implementing these features to the app in the future. If you have any other ideas, do not hesitate to let us know.
Works great, but missing one key feature
I’m glad that an app where I can adjust the pitch of the audio on some of the videos exist and I would use it regularly if it didn’t miss one key feature: the ability to save it in my photos. I find it ridiculous that when it comes to saving, I’m limited to the iCloud, Dropbox, email or a folder where other apps can’t get access to. If it just allowed users to save it in photos, I would give this app five stars.

Hi MrGrimmace - Thanks for the nice feedback, we're glad that you're enjoying the app! Unfortunately, video export is currently not available in the app, so you won't be able to export it to your Photos. We'll consider creating this option in future updates.
Finally, a good audio tool app
Brilliant app. AB looping, marker, mono/stereo L/R settings, smooth backwards/fwds scrolling playback, fast/slow/backwards tempo control, pitch control spectrum piano roll display and background playing!!
What sold me was that you import audio from any sources, not just iTunes(don’t know any would). So this app goes great with AudioShare. You can also import video(mp4 I think)
