Go to Pitch ChangerWhat is Pitch Shifting?
Pitch shifting changes the frequency of audio without changing its speed. Raise the pitch to make voices sound higher (like a chipmunk) or lower it for a deeper, bass-heavy effect. Musicians use it to change keys, and content creators use it for voice effects.
How to Use the Pitch Changer
Drop any video file with the audio you want to pitch shift.
Click the Pitch button and use the slider to adjust semitones (−12 to +12).
Convert and download your pitch-shifted audio as MP3.
Understanding Semitones
A semitone is the smallest interval in Western music — the distance between two adjacent piano keys. Here's what different pitch shifts sound like:
- +12 semitones: One octave higher (double frequency) — very high, chipmunk-like
- +5 semitones: Noticeably higher voice, but still natural
- 0 semitones: Original pitch (no change)
- −5 semitones: Deeper voice, more bass
- −12 semitones: One octave lower (half frequency) — very deep, bass-heavy
