Pitch Shifter
Shift the pitch of your audio up or down by up to 12 semitones without altering the playback speed. Transpose a song to match your vocal range, create a chipmunk effect, or deepen a voice for creative content. Singers and musicians use pitch shifting to move a backing track into a more comfortable key before practicing or recording a cover, while podcasters and video creators use extreme shifts for character voices, anonymization, or comedic effect. Because tempo stays locked while pitch moves independently, the timing of vocals, beats, and instrumentation stays perfectly in sync no matter how far you shift. Preview your changes in real time before exporting, and export in MP3 or WAV once you've found the right semitone offset.

How do I match a song to my vocal range?+
Upload the song, then use the slider to adjust semitones until it feels comfortable for your voice.
