How the Audio Speed Changer Works

Set the playback speed anywhere from 0.25x up to 3.0x. Note that this changes both speed and pitch. The tool exports the modified result as a new WAV file.

Usage Example

Slow down a fast talker to make it easier to understand.

Frequently Asked Questions

Does this keep the pitch?

No, changing the speed with this tool naturally changes the pitch (just like speeding up or slowing down a vinyl record).
