How to change the pitch of audio without changing speed

Upload a file (or record) up to a minute long.
Move Pitch in semitones: +12 is an octave up, −12 an octave down, ±1 moves the song by one key.
Raise Smoothness for full songs and chords; lower it for drums and speech.
Compare with the original, then download the WAV.

Pitch shifter vs autotune

A pitch shifter moves everything by the same amount; it doesn't care whether notes are in tune. Autotune measures each note and moves it to the nearest correct pitch. To fix an off-key vocal, use the online autotune instead. To shift and also tune a vocal inside your DAW, Tune does both with formant control, so voices don't turn into chipmunks.

People also ask

How do I change the pitch of a song without changing the speed?

Use a pitch shifter that time-stretches as it transposes, like this one. Upload the song, move the Pitch slider by semitones, and download the result. The tempo stays exactly the same while the key moves up or down.

How many semitones is an octave?

Twelve. Shifting by +12 semitones raises audio one octave and doubles its frequency; −12 lowers it an octave. Shifting by one semitone moves the whole song to the next key up or down.

Does pitch shifting reduce quality?

Large shifts add some artifacts, especially on full mixes. Keep shifts within about ±4 semitones for natural results, raise Smoothness for chords and full songs, and use a formant-preserving tool like Tune for vocals.

Is pitch shifting vocals different from shifting a whole song?

Yes. A plain pitch shifter moves the formants along with the notes, so a vocal shifted up sounds small and a vocal shifted down sounds slow and murky. For more than a couple of semitones on a voice, use a formant-preserving vocal pitch shifter such as Tune, which keeps the singer's character while the pitch moves.
