Music Speed Changer is a music player app with a simple UI. You can use it to play your music at different speeds, including very fast, super fast, and even faster than the original.

To begin with, you need to install the app and open it.

If you want to change the pitch, you need to slide the slider either to the left or right. This way, you can choose the value from -24.0 to +24.0 semitones.

If you want to change the tempo, you need to slide the slider in either of the opposite directions.
