About this tool
Move a song or beat into a key that suits your voice, slow a song down to learn it, or speed it up for a sped-up version. Change pitch and speed separately, or untick "Keep the pitch" for a classic record-style slowdown or speed-up.
Questions
Can I change the key without changing the speed?
Yes. Leave Speed at 100% and move Pitch up or down in semitones.
How do I make a slowed or sped-up version?
Untick "Keep the pitch" and move Speed. Slower sounds deeper, faster sounds higher, like changing the speed of a record.
How many semitones is one key?
Each semitone is one step on the piano. +2 moves C major to D major; −12 is one octave lower.
Is my file uploaded?
No. Everything runs on your device. Nothing is uploaded.
