Wrong key for your voice? Move the song, not the singer.
Shift the whole track up or down by semitones — the tempo stays put, the words stay clear, and the export is a clean WAV. Singers, capo-averse guitarists, and horn players: welcome.

±2 is invisible · ±4 is usable · ±6 starts to talk — that's every whole-mix shifter, honestly. Move the slider and it previews live. Shift-drag the waveform to loop a phrase (A–B); play, loop, and volume live in the player bar.
±2 semitones is invisible. ±6 starts to talk. Real keys need real stems.
Whole-mix pitch shifting keeps artifacts low at small moves and gets chewy at big ones — that's the physics of shifting everything at once. SongTranscribe in the studio works from the song's actual notes: MIDI you can put in any key, cleanly, forever. Sign up: 3 full packs free.
Finding your key, fast
Singers: play the original and hum along on the chorus's highest line. Straining? Come down a semitone at a time until the top note sits comfortably — most voices land within two or three semitones of the original. Guitarists avoiding barre chords: −2 turns many B-and-F♯ songs into A-and-E songs. Horn players: your transposition chart already knows the number; type it here.
The preview renders the middle fifteen seconds so you can judge the vocal — that's where artifacts show first. Happy? Render the full song once and keep the WAV.

Frequently asked questions
How do I change the key of a song?
Drop the file, pick how many semitones up or down (E to G is +3, C to A is −3), preview, and export. The engine — Signalsmith Stretch, a genuinely good time/pitch library — shifts pitch while holding tempo and correcting formants so voices don't go chipmunk.
How far can I transpose before it sounds bad?
±2 semitones is effectively transparent on most mixes. ±4 is usable. By ±6, drums lose snap and voices take on a processed sheen — every whole-mix shifter does this, whatever it costs. For bigger moves you want the song's notes, not its audio.
Will the tempo change when I transpose?
No — pitch and tempo are decoupled. Your 92 BPM stays 92 BPM in the new key.
What's the difference between this and a capo?
A capo moves your guitar; this moves the recording. Practicing along in your key without retuning anything is exactly what it's for.
