Music Speed ??Changer allows you to change the speed of the 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 can be adjusted together with a single control. The app is also a music looper * you can slow down the speed of the song and repeat sections of the music for easy practice. Another feature is the ability to reverse audio (play music in reverse). You can also save the adjusted audio to an MP3 (.mp3) audio file to share with friends or listen to it in another player.
