Frequently asked questions

How do I change audio speed?

Choose your recording, move the speed slider or select a preset, then preview the change. Export your audio as MP3 or WAV when the pace feels right.

Does changing speed change the pitch?

The speed control preserves the pitch. A faster setting shortens the recording, while a slower setting makes it longer. Use Audio Pitch Changer to adjust the pitch separately.

Which speeds can I choose?

Choose any speed from 0.5× to 2× in steps of 0.01. The new duration is shown beside your settings before you export.
