Music Speed Changer

Independently adjust the speed and pitch of your music and other audio.

Music Speed Changer lets you modify the speed of audio files on your device in real time without altering the pitch (time stretch), or change the pitch without affecting the tempo (pitch shift). You can also adjust both speed and pitch simultaneously with a single control. Additionally, it functions as a music looper—slow down tracks and seamlessly loop sections for effortless practice.

Save your modified audio to MP3, FLAC, or WAV files for sharing or listening in other media players.

Ideal for musicians practicing instruments who need to slow the tempo or change tuning, speeding up audiobooks for efficient listening, creating nightcore, or rocking out to your favorite songs at 130% speed.
