How to Use the Audio Speed Changer

Drag the slider to set the speed from 0.25x to 3.0x. Pitch is preserved, so voices and music keep their original tone while playing faster or slower. -
Play and Copy the Summary
Press Play to preview the adjusted audio, then use the Copy Result button to copy the file details and playback summary to your clipboard.
