AudioStretch Lite: The Ultimate Music Transcription Tool

AudioStretch Lite is an iPhone app developed by Cognosonic Pte Ltd that allows you to slow down, loop, and auto-transpose the notes of any piece of music you want to learn. Its unique features make it the world’s first audio and video transcription tool. With this app, you can manipulate the pitch and speed of audio and video files, or capture video directly into AudioStretch using your phone’s camera.

One of the most significant advantages of AudioStretch Lite is that you can change the speed of files without changing the pitch, making it easier to learn songs by ear. Additionally, you can listen to individual notes as you drag the waveform, play audio and video at zero speed, transpose any music, and loop difficult sections. The app is incredibly responsive and easy to use, making it ideal for transcription, learning songs, and experimenting with sound.

Note that this is the LITE edition of AudioStretch, which has a few feature limitations. The full version has no limitations and offers additional features such as longer song duration, wider speed range, and pitch shift.
