Transpose the audio by exact semitones, preview the result, and adjust speed separately when needed.
A pitch changer raises or lowers the musical pitch of a song, backing track, voice, instrument, or sound effect. The default workflow keeps the original duration, so the key changes without making the audio play faster or slower.
Adjust the track in semitone steps, preview every change before processing the complete file, and export the result in a practical audio format.
Move from one octave down to one octave up, with clear half-step presets for common musical changes.
Leave speed at 100% for a pure key change or adjust it separately when the project also needs retiming.
A short processed preview refreshes after pitch or speed adjustments so you can confirm the result first.
Create WAV, MP3, M4A, FLAC, or OGG without replacing the original file on your device.
Start at zero semitones, then make the smallest musical shift that fits your voice, instrument, or creative idea.
Choose a song, backing track, voice recording, instrument take, loop, or sound effect.
Use a preset or set an exact value from -12 to +12 semitones. Keep speed at 100% when only the key should change.
Play the automatically refreshed preview and check vocals, transients, and the intended musical range.
Process the complete track and download the pitch-changed WAV, MP3, M4A, FLAC, or OGG.
Pitch changing is useful whenever the notes are correct but the complete recording needs to sit higher or lower.
Transpose a backing track into a more comfortable part of your vocal range without changing its tempo.
Match an alternate tuning, capo position, transposing instrument, or rehearsal key.
Retune loops, samples, demos, and references so they fit a project or harmonic-mixing plan.
Create higher, lower, brighter, or heavier variations of voices and sound effects.
Choose the tool according to the part of the sound you need to change.

Yes. Keep Speed at 100%. The pitch moves by the selected number of semitones while the duration stays close to the original.
The control covers -12 to +12 semitones, equal to one octave down or one octave up.
Yes. A processed preview updates automatically after every pitch or speed adjustment.
The main Pitch Changer exports WAV, MP3, M4A, FLAC, and OGG. The dedicated MP3 page keeps both input and output focused on MP3.
Extreme changes move every part of the recording by a large interval. For full songs and vocals, shifts of one to three semitones usually retain the most natural character.
No. A pitch changer transposes the complete recording by a fixed interval. Pitch correction detects individual sung notes and moves them toward a scale.
