Quick answer
How do you change the pitch of a song?
To change the pitch of a song, choose the file in the tool above, move the slider up or down by semitones, press Preview to hear 20 seconds, then press Download WAV. The tempo and length stay the same. It's free with no account, and the file is never uploaded. You can shift up to 12 semitones either way in 0.1 steps. Small shifts of 1 to 3 semitones usually sound the most natural.

- Singing along
- Move 1 to 3 semitones to fit your range.
- Playing along
- Match a track to a tuned-down guitar: −1 for a half step down.
- DJ mixing
- 1 or 2 semitones brings two tracks into a matching key.
- Off-pitch recordings
- Fine steps of 0.1 to 0.5 fix a track that sits between notes.
- Sound design
- 7 to 12 semitones for an effect, not a natural result.

Tips
Cleaner pitch changes
What helps, and what to expect.
Use the smallest shift that does the job. The further you go, the more you'll hear the processing.
Held notes and pads can pick up a slight ripple, and it's easiest to hear on big shifts.
Start from the best file you have. A shift won't remove the artefacts of a low-bitrate MP3.
Find the song's key first with the BPM and key finder, so you know how many semitones you need.
Pitch-shift once from the original. Repeated passes add up.
Only process music you have the rights to use.
FAQ
Pitch Changer questions
10 questions
How do I change the pitch of a song without changing the speed?
Load it into the pitch changer above, set the number of semitones and download the WAV. The tool stretches the audio and then resamples it, so the pitch moves while the tempo and length stay the same.
Link to this answerIs this pitch changer free?
Yes. There's no account, watermark or limit on how many files you process, one at a time. The only limit is 60 MB per file.
Link to this answerIs my audio uploaded?
No. Opening, previewing and exporting all happen in your browser, so the file stays on your device.
Link to this answerHow many semitones can I change the pitch?
Up to 12 either way, which is one full octave. You can also move in 0.1 steps for fine tuning. Small shifts of 1 to 3 semitones usually sound the most natural.
Link to this answerCan I use this as a voice pitch changer?
Yes, for a recorded file. A small shift works for a voice-over or a singing take. Large shifts sound cartoonish, because the tool moves the whole voice and doesn't correct its formants. It doesn't change your voice live.
Link to this answerHow do I change a song's key?
Each semitone moves the song one key: +2 takes C major to D major, and −3 takes C major to A major. Use the BPM and key finder to see the current key, then count the steps.
Link to this answerCan I convert a song to 432 Hz?
You can get close. Moving a song tuned to A = 440 Hz by −0.3 semitones puts A at about 432.4 Hz. Whether that sounds better is a matter of taste.
Link to this answerCan I save as MP3?
No, the tool only writes 16-bit WAV. WAV opens in almost every editor, and you can convert it with a desktop tool if you need a smaller file.
Link to this answerCan I change the pitch of a YouTube or Spotify song here?
No, it only works on audio files on your device. It can't reach music playing on a streaming site.
Link to this answerWhat's the difference between this and the BPM changer?
They're opposites. The pitch changer moves the pitch and keeps the tempo. The BPM changer moves the tempo and keeps the pitch. Slowed and reverb changes both together, like a turntable.

Pitch Changer, explained
What works, what to avoid, and how the pieces fit.

How a pitch change works without changing the speed
If you just play audio faster, it gets higher and shorter together. To move only the pitch, the tool works in two steps [1]. It first stretches the audio longer or shorter by the amount you asked for, using a method called WSOLA that joins small slices where the waveforms line up. Then it resamples the result back to the original length, and that resampling is what moves the pitch.
A semitone is a frequency change of about 5.9% [2], so 12 semitones doubles or halves every frequency. That's why a whole-octave shift is such a big change, even though the slider only moves 12 steps.
Voice pitch changer: what to expect on speech and vocals
Recordings of people are harder than instruments. A voice has resonances called formants that give it its character, and a plain pitch shift moves them along with the notes [1]. That's why a voice shifted up sounds like a chipmunk and one shifted down sounds huge and slow.
This tool doesn't correct formants. For a voice-over or a singing take, stay within about 2 semitones if you want it to pass as natural. If you need a different voice rather than a nudged one, Kenerate's text to speech tools make a new voice-over from your script.
What we measured
We tested the tool on 4 November 2026 in Edge on one Windows desktop, using generated test files. We measured these results and didn't judge them by ear. Your times will differ, and we haven't measured phones, Safari, Firefox or Chrome.
- Pitch accuracy — test tones at 220, 440 and 1,000 Hz landed within about 2.5 cents of the target, from 0.5 to 12 semitones in both directions. A cent is a hundredth of a semitone.
- Length — the output had exactly as many samples as the input at every setting.
- Held tones — steady test tones showed a measurable ripple, which is why we warn about pads and long notes.
- Three-minute stereo M4A — opened in about 0.25 seconds. A preview took under half a second, and the full export took 0.7 to 3.6 seconds, making a 31.8 MB WAV. Shifting up took longer than shifting down.
When a browser tool isn't the right fit
This pitch changer suits one file you want to keep private. Use something else in these cases:
- Live pitch change on a streaming site — that needs a browser extension, and this page can't reach another site's audio.
- Natural-sounding big vocal shifts — use a desktop editor with formant correction.
- Files over 60 MB, batches or MP3 output — use a desktop audio editor.
- Change the speed instead — the BPM changer keeps the pitch and moves the tempo.
