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!

This app is a game changer!!!!!
One of my hobbies is that I sing 4-part barbershop music. The most conventional way to learn our music is that we get learning tracks with your part in one ear(channel) and the 3 other parts in the other ear.
I have had other apps that also have the ability to slow down, change keys, block off sections to work but the biggest change with AudioStretch is that you can listen to a note or chord as long as you wish as long as your finger is on the screen. The feature is awesome when something is really fast or hard to hear.
You can also load your own video and do the same thing there.
The other feature that is different is that you cal load a piano bar at the top of the screen. It shows which notes are being sung and the overtones that are produced.
If you learn your notes visually, this will help.
This is the best out there to learn music. It might cost a little it is so worth it!!!!!
As I mentioned earlier, I do have another similar app that has a lot of the same features. The one thing it has that AudioStretch does not have currently is the ability to keep a list of files that have been uploaded previously. It makes it easier to go back and forth to different files.
If that feature were to be added, it would have everything I need.
Thank you again for a great app!!!!!!

Wow! Thank you for the amazing review, wstuttsjr! We really appreciate it.
This app was suggested in a Facebook group and happened to get some great comments and the price was great! I went ahead and purchased the full version and have no regrets! In fact, just yesterday I recorded a bass line in a higher octave that was triggering a synth app. I decided I wanted a low octave to synch with it, but playing the bass line over exactly like the original would be virtually impossible! I exported the original bass line into the AudioStretch app and lowered the pitch down a full octave without slowing the file and there was very little sound degradation! I then exported back to my DAW and it was perfect!
Another great feature is this app will change video audio without changing the video itself...just the audio. It really saves some steps if you are editing a video!
I highly recommend this app! 😊💖✨

Recent Bug! Fixed!
Recently I have encountered issues importing tracks from my iCloud. Sometimes, the same track would download and other times it won’t. I have no issues with internet connection. This has happened frequently with different tracks (MP3’s). I emailed Support a few weeks ago but hasn’t received a response. This is just a recent issue because I have been using the app for many years with no problem. I will upgrade the one star to 5 once I get a response and a resolution. BTW, I deleted the app and installed it several times. I’m using iPhone 11 Pro Max.
When I restarted my phone the app worked fine. I’ll give back the 5 stars to my favorite app.
