Pitch Changer Online Free
Shift the pitch of any audio up or down by semitones and cents. Live preview, precise control, free.
Change Pitch with Precision
The pitch changer offers two levels of control: • Semitones — shift pitch in half-step increments (piano keys). Range: -24 to +24 (two octaves in each direction). • Cents — fine-tune within a semitone. Range: -50 to +50. 100 cents = 1 semitone. This gives you musical precision. Transpose a song to a different key, correct pitch, or create creative effects.
Use Cases
• Transpose a song to match your vocal range • Shift a backing track to match another instrument's tuning • Create chipmunk (pitch up) or deep (pitch down) vocal effects • Correct slightly out-of-tune recordings • Adjust the key of a karaoke track • Experiment with how a song sounds in different keys

Open Speed & PitchFrequently Asked Questions
They're the same thing. Transposing is the musical term (moving notes to a different key). Pitch shifting is the audio term (changing the frequency of the sound). Both mean: making it higher or lower.
It depends on the mode. Classic pitch shift (like speeding up a vinyl) changes both pitch and speed. Modern pitch shifting can change pitch independently of speed using time-stretching algorithms.
