Try a sample track

Material that transposes well, and badly

Instrumental tracks shift cleanly; exposed vocals are where formants give a shift away. These six cover both ends.

The audio pitch changer moves the key and leaves the tempo alone

A new key, at the original tempo

Transposition here leaves length and speed untouched, so the result still sits against material you have already recorded.

When you want the slowed sound

Changing speed as well as pitch is the slowed and reverb page, not this one.

How Audio Pitch Changer works

Change key without changing tempo in three steps

1

Upload the audio to transpose

Bring in a song, a stem or a spoken recording - the shift applies to whatever you send.

2

Move key without moving tempo

Shift the pitch up or down in semitones while the track keeps its original length and speed.

3

Export at the new key

Download the transposed file ready to sit next to material already in that key.

Audio Pitch Changer features

Audio Pitch Changer shifts a supplied recording up or down in semitones. Speed and reverb are separate controls, so you can compare treatments and export the processed audio as WAV.

Move up or down by semitones

Choose a pitch shift from -12 to +12 semitones. Larger changes can alter the tone of a voice or instrument, so compare the processed result with the original.

Pitch and tempo are two decisions, not one

Open Advanced Settings for the pitch control. For a pitch-only edit, choose Original or set speed to 1x and reverb to 0 before adjusting semitones.

Producers fitting a sample

Transpose a sample into the project key rather than rebuilding the part.

Move the key, keep the tempo

Shift pitch on its own, and the length of the track never changes.
