Tunedzy Key and Speed
Updated October 2026
Key and speed changes the key or the speed of a clip. Small changes sound natural; large changes can add artifacts. Keep the original, and check the highest and lowest notes after each change.
The short version
- Change the key by semitones, or the speed of a clip.
- Small changes sound natural; large ones can smear.
- Keep the original and listen to the whole clip.
- Check the range for a vocal after a key change.
What it changes
Key moves a clip up or down in pitch by semitones. Speed changes how fast the clip plays, with the pitch kept where the tool allows it.
Limits
Large changes add artifacts and can change how a voice sounds. Check the highest and lowest notes, and listen on a phone speaker.
Guides
The key change guide and the speed guide explain the method.
