Made to fit your voice or your instrument

Move the song, not your range.

Singers and choirs

Bring a backing track down a step or two so the high notes sit where your voice is strong.

Players

Move a track into a key that suits your instrument, or slow it to 0.75x to learn a solo.

How far to move it

One semitone is one piano key. Small moves sound the most natural.

1 to 3 semitones

Sounds like the same singer on a different day. Best for fitting a voice.

4 to 7 semitones

Voices start to sound smaller or deeper. Fine for a backing track.

12 semitones

A full octave: the same notes, much higher or lower. Good for effects.

Pitch, speed, or both?

The two sliders are separate, so you choose what moves.

Questions about the Pitch Shifter

Can I change the key without changing the speed?

Yes. That is what the pitch slider does. The speed slider is separate and stays at 1x unless you move it.

How far can I shift it?

Up to 12 semitones up or down, a full octave. Moves of 1 to 3 semitones sound the most natural on voices.

How do I find a key that suits my voice?

Sing along with the chorus. If the top note strains, move down 1 or 2 semitones and try again. If it feels low and dull, move up.

Is the song sent anywhere to change the key?

No. Your browser reads and changes the file on your device and nothing is sent to us. Close the page and it is gone.

Why does it save a WAV?

WAV keeps the full sound and every app opens it. It is bigger than an MP3, so convert it later if you need a small file.

Can I hear it on a song first?

Yes. Load Gone With the Rain from the button under the drop zone. The song is in D major; move it down 2 steps and it plays in C major.

Can I change the speed but keep the key?

Yes. The speed slider runs from 50% to 150% and leaves the key where it is. Move the steps as well if you want both to change.

How many steps is one key?

Each step is one note on a piano. From D, up 1 gives E♭ and up 2 gives E. Twelve steps up or down is a full octave, the same key higher or lower.
