Free Pitch Changer

1. Upload an AAC, AIFF, FLAC, M4A, MP3, OGG, or WAV file.
2. Move the slider to your target shift — a semitone or two for subtle retuning, up to a full octave for a dramatic change.
3. Apply the shift.
4. Download the result — same tempo, new pitch.

Pitch is usually adjusted in semitones. Twelve semitones make one octave, so shifting a track by +12 moves every note one octave higher, while -12 moves everything one octave lower. Smaller adjustments of one or two semitones are commonly used to match a singer's vocal range or transpose a song into a more comfortable key.

Large pitch shifts are possible, but bigger changes naturally sound less realistic because voices and instruments take on different tonal characteristics as they move farther from their original range.

Pitch shifting comes up for singers practicing in a different key, musicians transposing a backing track, DJs preparing harmonically compatible mixes, producers building vocal effects, and content creators nudging background music to better fit a project. Because tempo stays fixed, everything stays synchronized — only the musical key changes.

Transpose a track into a more comfortable vocal range for practice, change the key of a karaoke track to match your own range, test how a sample sounds in a different key before dropping it into a session, or create a pitched-up or pitched-down variation for a remix — all without the tempo shifting along with it, which is what a simple speed change would do instead. It's also useful for DJ mashups where two tracks need to sit in the same key, and for instrument practice when you want to play along in a different range.

Not sure what key your source track is already in? Run it through the Key & BPM Finder first, then transpose it here to the key you need.

Need to trim the audio before transposing it? Use the Audio Trimmer first, then apply the pitch shift to only the section you need.

Need to change speed without affecting pitch? Use the Tempo Changer instead — it's the same underlying approach, applied to speed rather than key.
