MP3, WAV, M4A, OGG, or FLAC · nothing uploaded
Every sample is played in reverse order, so the file ends where it began, with no change in speed or pitch. The result is a lossless WAV file at the original sample rate. Reversed speech and cymbals are classic studio effects, and listening for hidden messages in reversed songs is an old pastime.
Uses
Reversed cymbals and vocals build tension before a drop, reversed reverb tails swell into a word, and reversed speech is a party game: record a phrase, reverse it, and try to say what you hear so it plays forwards again.
Smaller files
To share the result as an MP3 or M4A, pass the WAV through the audio converter.

Frequently asked questions
Why is the file bigger than the original?
WAV is uncompressed: a minute of stereo CD-quality audio is about 10 MB, where an MP3 might be 1 MB. Convert it back with the audio converter if size matters.
Can I reverse just part of a track?
Trim the part you want first with the audio trimmer, then reverse it.
Do songs have hidden backwards messages?
A few deliberate ones exist, but most claimed messages are the brain finding words in random sounds.
