- Choose the format to save it in.
- Press reverse and download.
Frequently asked questions
- Does reversing change the speed or pitch?
- No. The samples are played in the opposite order at the same rate, so it lasts exactly as long and sits at the same pitch. Only the direction changes.
- What is it good for?
- The reverse-singing challenge (reverse a phrase, learn to sing it backwards, reverse that), checking a song for a backmasked message, or a reversed cymbal or piano as a swell into a video cut.
- Can I reverse the sound of a video?
- This page takes audio. To reverse a whole clip, sound and picture, use the reverse video tool.
- Is my recording uploaded?
- No. It is reversed in your browser.
