Independently adjust the speed and pitch of your audio. Music Speed Changer lets you modify audio files in real-time without affecting pitch (time stretch), alter pitch without changing speed (pitch shift), or adjust both simultaneously. It also functions as a music looper, ideal for slowing down sections for practice.

Export modified audio as MP3, FLAC, or WAV files. This app is perfect for musicians needing to slow tempos or adjust tuning, speeding up audiobooks, creating Nightcore remixes, or simply enjoying your favorite tracks at a boosted 130% speed.
