How to change the key of a song online
Open the pitch changer
Visit the free pitch changer on the home page and upload your audio. Once it is prepared, select Change pitch / tempo. Finding the original key first is optional.
Set the pitch shift
Move pitch up or down in semitones. Leave tempo at 100% to keep the original pace, then choose Listen preview to apply your settings to the short excerpt.
Export the full song
When the preview sounds right, choose Download full track and an output format. After processing, play the finished audio and download it.
Pitch shifting in semitones
A semitone is one step between neighboring notes on a piano, including the black keys. Positive values raise pitch; negative values lower it. Twelve semitones make an octave, so the available range is one octave down to one octave up.
An audio pitch changer moves the whole recording by the same interval. It shifts vocals and instruments together. Use it as a song key changer for an existing backing track or as a music pitch shifter for a sample.
| Pitch setting | Resulting key | Change |
|---|---|---|
| −2 semitones | B♭ major | Down a whole tone |
| +2 semitones | D major | Up a whole tone |
| +5 semitones | F major | Up a perfect fourth |
| +12 semitones | C major, one octave higher | Up an octave |
Preview first, then process the whole recording
The working preview starts with the first 20 seconds of your source audio, or the complete track if it is shorter. Changing a pitch or tempo setting clears the previous preview. Choose Listen preview again to hear the new version.
The full export applies your chosen settings to the whole uploaded recording. Download WAV, MP3, FLAC, M4A, AAC, OGG, Opus, AIFF or WMA. Large pitch shifts may sound less natural, especially on a dense mix or a voice. Listen before exporting; a lossless output format cannot recover detail already missing from a compressed source.
Transpose backing tracks for your voice
For karaoke practice, start with a small adjustment: try one or two semitones lower if the high notes feel uncomfortable, then sing along with the preview. This changes the key of a backing track you already have; it does not remove the singer from a recording.
The song key finder overview explains the original key estimate you can use before transposing. To change pace as well, read about the music speed changer.
You can return to the Pitch Tempo home page to start a fresh audio session or sign in to save your work.
Questions before you start
Can I use this as an MP3 pitch changer?
Yes. Upload an MP3, preview a shift and export it as MP3 or another supported format. The same workflow works with WAV, FLAC, M4A and more.
Do I have to detect the key before changing it?
No. You can shift by semitones immediately after preparation. Run key detection first if you want to see the change relative to a named musical key.
Is a pitch shifter the same as Auto-Tune?
No. This pitch shifter transposes the complete recording uniformly. It does not correct individual out-of-tune notes or isolate the voice from the instruments.
Can I hear every change immediately?
Choose Listen preview after adjusting the controls. Processing takes a moment; it is not a live effect while you move the slider.

Upload an MP3, WAV, M4A, AAC, FLAC, OGG, Opus, AIFF or WMA file. Each track can be up to 100 MB and 5 minutes long. A readable audio recording is required; an unsupported, damaged or protected file may not open.
