Fun things to do with reversed audio

People use an audio reverser for all kinds of reasons, from quick experiments to finishing touches on a track.

Try the say-it-backwards challenge.

Record a short phrase, reverse it, and copy the strange sound you hear. Reverse your attempt to see if the original words come back.

Listen for hidden messages.

Flip a song and see what you can hear. People have been doing this with records for decades, and some artists really do hide a line or a joke for fans to find.

Make spooky sounds for videos.

A backwards whisper, door creak, or breath gives Reels, TikToks, and short films a strange, dreamlike feel.

Build a riser from a crash.

Reverse a cymbal hit and it swells upward into the beat, the classic sound right before a drop.

Start a track with a backwards intro.

Reverse the last second of a vocal line and put it in front of the verse.
