A little more about this tool
A semitone is one step between adjacent piano keys, including black keys. Moving a song from C to D takes two semitones; moving it from C to B takes minus one. This tool changes the whole recording, including voices and instruments. It does not separate stems or preserve vocal formants, so large changes can alter the character of a singer. For transposing written chord symbols, use the capo and chord transposer instead.
Can I change pitch and speed separately?
Yes. Pitch controls the transposition in semitones, and speed controls playback tempo. Changes take effect when you press Play again.
Is it really free?
Yes. Use this tool without an account, subscription or download. Audio files and microphone input stay on your device. Browser format support varies; MP3 and WAV are good starting points.
