Free Online Pitch Shifter
Pitch shifting resamples the audio to move the frequency, then time-stretches it back to the original length, so the clip lasts the same time but sounds higher or lower. +12 semitones is one octave up; −12 is one octave down.

Questions about Pitch Shifter
Does changing pitch change how long the file is?
No. The tool restores the original duration after shifting, so only the pitch moves, not the timing.
What is a semitone?
The smallest step in Western music — one key on a piano. Twelve semitones make an octave, so +12 doubles the frequency and −12 halves it.
About Pitch Shifter
Shift the pitch of audio up or down in key with our free online Pitch Shifter. 100% browser-based, fast, and private—no login or file uploads required.
These audio tools edit sound without a desktop editor: trim and join clips, convert formats, record from microphone, and adjust volume, speed, pitch or equalisation while you listen to the result.
This tool runs in your browser. The file is not uploaded. Work on a copy and preview before downloading: trimming and speed changes are destructive to the loaded clip, and re-encoding a lossy file twice adds audible artefacts.
