About & Pics

Description

The most downloaded time stretching and pitch shifting app in the Play store, now with élastique engine for professional sound quality.

Music Speed Changer allows you to change the speed of audio files on your device in real time without affecting the pitch (time stretch), or change the pitch without changing the speed (pitch shift). Alternatively, both speed and pitch may be adjusted together with a single control. The app is a music looper as well - you can slow down song speed and loop sections of the music for easy practice. Another feature is the ability to reverse audio (play the music backwards).

You can also save the adjusted audio to an MP3 (.mp3) audio file for sharing with friends or listening in another player.

Music Speed Changer is great for musicians practicing an instrument needing to slow down the tempo or practice in a different tuning, speeding up audio books for faster listening, making nightcore or just rocking out to your favorite song at 130%.

Notice for Google Play Music users: Google places DRM on songs purchased through Google Play Music. Your songs purchased in that app will not be visible in Music Speed Changer (or any other music player). A simple way around this is to download the purchased songs through the Google Play Music desktop browser app, then transfer the downloaded .mp3 file to your Android device.
