How to change the speed of audio
- Choose your audio file.
- Pick a speed and keep the normal pitch or not.
- Press the button and download.
Good to know
- Keeping the pitch uses time-stretching, so voices stay natural.
- To change the pitch without changing the speed, use Change Pitch.
- MP3 stays MP3, M4A stays M4A.
