Music Speed Changer

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

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