How it works
The Audio Reverser flips your entire recording backwards, sample by sample - the digital equivalent of playing a tape in reverse. Cymbal crashes become swelling crescendos, reverb turns into ghostly pre-echoes, and familiar sounds become wonderfully alien.
It is a pure reordering of the sample data, so the operation is perfectly lossless: reverse a reversed file and you recover the original bit-for-bit. There are no settings because none are needed - one click, instant backwards audio.
Like every tool here it is 100% client-side: the reversal runs in your browser tab, your files never leave your device, and nothing is uploaded to a server.
Frequently asked questions
What does reversed audio sound like?
Backwards: cymbals swell instead of crash, reverb tails become eerie pre-echoes, and speech turns into the famous "backmasking" gibberish. It is a classic creative effect in psychedelic rock and electronic music.
Does reversing lose quality?
No - reversing just reorders the samples. It is mathematically lossless; reverse it again and you get the exact original back.
Can I reverse only part of a file?
Use the Audio Trimmer first to cut the section you want, then reverse that clip.
Is there a file size limit? Is it private?
Files up to 100MB are supported. Reversing happens instantly in your browser - your audio never leaves your device.
