Change speed quickly

Use this tool to change the tempo of any audio file of your choice. If you feel like a song is too slow for you, you can easily speed it up without changing its key. You can also slow a song down which can be useful if you want to transcribe a song.

Play along with songs

If you are a beginner with an instrument and want to play along with your favorite song you can use this tool to help you. Slow down the song to a comfortable tempo that you can play along with and then raise the tempo progressively as you get better.

Maintain pitch

Normally when changing the speed of an audio track with other tools, the pitch is also changed. We use advanced pitch shifting algorithms to prevent this and to keep the original pitch of the track.
