App Description

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!

FEATURES INCLUDE:

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.
