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 tempo and pitch may be adjusted together with a single control. The player is a music looper as well - you can slow down song speed and loop sections of the music for easy practice. The simple to use audio editor is integrated into a music player with playlists, playing queue, preamp, blance, equalizer, and effects. You can use Music Speed Changer to create new tracks or use it as a real time audio manipulation tool, on-the-go correction tool, and as a music learning aide. It is a musician's and music lovers' complete all in one pocket tool and music player. As a learning tool, the app helps you slow down and loop difficult parts and raise or lower the pitch of any music to suit your range. Alterations can be saved to a new audio track. The editor features A/B repeat looping, key and BPM detection, and the ability to bookmark parts of tracks by setting markers. These learning tools make the app useful for students and teachers of music, dance, language, and academic subjects. The app's real-time editor is fully integrated into the music player with the ability to affect its playlists and queue. This means you can play your entire music collection with an upbeat tempo for working out and running or slow down and reverb a selection of your music collection for relaxing.
