Transpose a song up or down by up to 12 semitones while the tempo stays put - studio-grade time-pitch stretching, running on your device.
100% in your browser - your files never leave your device.
That's the actual device from the TuttiDAW studio. Dial it in, then drop a file above - it opens right in the (free, no-signup) studio with this device on the track: listen live, keep tweaking, and export from there.
Any MP3, WAV, OGG, FLAC or M4A. The file is decoded by your browser and never uploads anywhere - which is also why preview starts instantly.
Dial the semitones on the actual Pitch Shifter device from the TuttiDAW studio - the same processor the editor uses, interactive right on this page.
Dropping the file opens it straight in the free TuttiDAW studio with the Pitch Shifter already on the track - listen in realtime while you adjust, then export a WAV in one click. No sign-up needed.
Singers use pitch shifting to move a backing track into a comfortable key: two semitones down can be the difference between straining and soaring, and the tempo you rehearsed at stays exactly the same. Guitarists shift songs to match a tuning - a track shifted -1 semitone plays along with a guitar in E♭ standard without retuning.
It is also an ear-training and transcription aid (shift a solo up an octave to hear a muddy bassline clearly), a remix tool (nudge an acapella into the key of your instrumental - check both keys first with the key finder), and a quick fix for old recordings that drift a quarter-tone from concert pitch.
Naive playback-speed tricks change pitch and tempo together, like a record player. This tool uses a proper time-pitch stretch: the audio is re-synthesized so the pitch moves while the timing, groove and length stay identical. Expect natural results within a few semitones; extreme shifts (±12) are creative territory on any engine.
No. This is a time-pitch stretch, not a resample: the length, tempo and timing of the audio stay exactly the same while the pitch moves by the chosen number of semitones.
Within about ±3 semitones most full mixes stay clean. Vocals keep their character further with small shifts; past ±7 semitones any pitch shifter starts to sound processed - sometimes exactly the effect you want.
No. Decoding, stretching and WAV encoding all run inside the page on your device. That also means there is no queue and no file-size billing - processing power is your own machine’s.
Dropping your file opens it in the free TuttiDAW studio (no sign-up) with the Pitch Shifter on the track. Press Space to listen, adjust the semitones live, then hit the Export button in the banner - the WAV renders offline, usually much faster than the song plays.
Uncompressed 16-bit WAV at your device’s sample rate - the safest format to bring into any DAW or editor without another generation of lossy encoding.
