How the Audio Speed Changer Works

Adjusts the playback speed of an audio file from 0.25x to 3.0x. This will change both the speed and the pitch of the audio. Exports the modified result as a new WAV file.

Usage Example

Slow down a fast-talking recording to understand it better.

Frequently Asked Questions

Does it preserve the pitch?

No, changing the speed using this tool naturally affects the pitch (like playing a vinyl record faster or slower).
