A song sits just too high to sing along to, or a backing track needs to match your instrument’s tuning. This free audio pitch changer moves a recording up or down in semitones — a whole octave is 12 semitones — while keeping its speed and length exactly the same, so it still lines up with lyrics, dance steps, or a video. Everything is processed in your browser, so your audio is never uploaded, and no signup is needed. Be honest about the limit: this is browser audio processing, not a studio-grade pitch engine, and very large shifts can start to sound artificial.
How to use this audio pitch changer
Drop a file, pick a shift, download the new key.
Drop in an MP3, WAV, or other common audio file. The original file is never changed.
Move the pitch up or down — try −2 for a song that sits too high, or +2 for one that sits too low. Fine-tune in cents for a recording that is slightly out of tune.
Listen to the shifted version first, then download it as a new file in the same length and tempo as the original.
Why this audio pitch changer keeps tempo and key separate
Speeding a record up used to raise its pitch too. This tool undoes that link.
Shift by semitones or cents while the duration and beat stay put, so a 3-minute song stays 3 minutes at the same BPM.
One semitone is one piano key, 100 cents make a semitone, and 12 semitones make an octave — the controls speak the language musicians already use.
Hear the new key on the same passage before downloading, so a wrong shift costs seconds, not a wasted export.
Processing happens on your own device, so an unreleased demo or a personal voice recording never leaves your browser.
Audio Pitch Changer FAQs
Short, direct answers to the questions readers ask most.
Yes. Keep the tempo at its original setting and move only the pitch control — the song keeps its length and BPM and only its key changes.
Start small: −1 or −2 semitones for a song that sits slightly too high, or +1 or +2 for one that sits too low. Larger shifts sound less natural, so try the smallest shift that feels comfortable.
A semitone is one piano key, and each semitone contains 100 cents. Use semitones to transpose into a new key and cents to correct a recording that is only slightly sharp or flat.
Small shifts usually sound clean, but very large shifts can sound artificial or thin — that is a limit of browser processing, not a fault in your file. Preview first and keep shifts modest for the best result.
