What Is Pitch Shifting?

Pitch shifting changes how high or low a song sounds — measured in semitones (the smallest step in Western music, e.g. C to C♯). Unlike simply speeding up or slowing down playback, proper pitch shifting keeps the tempo exactly the same while only changing the key.

Our pitch shifter uses formant-preserving processing, so voices and instruments keep their natural character instead of sounding thin or robotic — no "chipmunk" effect going up, no "demon voice" effect going down.

Frequently Asked Questions

Is the pitch shifter really free?
Yes, completely free. No trial period, no credit card, no catch.
Does the tempo change too?
No. Pitch shifting changes only the key — the song plays at exactly the same speed and length as the original.
Why is the range limited to −4 to +4 semitones?
Within this range the formant-preserving processing sounds natural. Larger shifts start to introduce audible artifacts, so we keep the range where quality stays high.
What audio formats can I upload?
You can upload MP3, WAV, FLAC, M4A, AAC, OGG, AIFF, and most other common audio formats. Maximum file size is 100 MB.
What format is the output file?
The pitch-shifted track is delivered as a high-quality MP3 file.
