Change Audio Pitch Online — Free, No Download
This pitch changer lets you shift the pitch of any audio file without changing its speed or duration. Upload a voice recording, music track, or any audio file, then adjust the pitch up or down by up to 12 semitones (one full octave). The two-pass resampling algorithm ensures the audio plays at the same speed regardless of pitch changes — no chipmunk effect when going up, no slow-motion when going down. Perfect for matching vocal keys, creating character voices, transposing music, or building harmonies. All processing happens locally in your browser using the Web Audio API.
Pitch Changer vs. Speed Changer — What Is the Difference?
Pitch and speed are related but independent properties of audio. Changing speed (the Audio Speed Changer tool) alters how fast the audio plays while keeping the pitch the same — useful for speed-listening podcasts or slow-motion music practice. Changing pitch (this tool) alters the musical note while keeping the duration the same — useful for key transposition, voice effects, and harmony creation. In raw audio, speed and pitch are linked: speeding up audio raises the pitch (chipmunk effect), and slowing down lowers it. Our tools use advanced algorithms to decouple them, letting you adjust each independently.
Change a Song's Key with an Online Pitch Shifter
Use the pitch shifter to move a song, backing track, vocal, or sound effect up or down in semitone steps while keeping the same speed and duration. Pick an interval, compare the original with the shifted result, then download MP3 for easy sharing and practice or WAV for an uncompressed file. Smaller shifts usually sound more natural; larger octave changes work well for obvious character and sound effects.
Frequently asked questions
What is pitch shifting?
Pitch shifting changes the musical pitch of audio without changing its speed or duration. Shifting up makes voices higher (like a chipmunk), shifting down makes them deeper (like a giant). This is different from simply speeding up or slowing down audio, which changes both pitch and speed simultaneously.
Can I change pitch without changing speed?
Yes — that is exactly what this tool does. It uses a two-pass resampling algorithm: first it shifts both pitch and speed, then it time-stretches the result back to the original duration. The output is the same length as the input but at a different pitch.
What is the pitch range?
You can shift pitch up or down by up to 12 semitones (one full octave) in either direction. For voice effects, 3–5 semitones produces noticeable but natural-sounding results. For dramatic effects like chipmunk or deep voice, try 7–12 semitones.
