Reverse Audio
Play any audio backwards โ the classic tape-flip effect, lossless.
About this tool
One click, every sample reversed, preview and WAV download. Reversing twice returns the exact original file โ the operation is perfectly lossless.
Sixty years of backwards audio
Tape engineers discovered the effect by physically flipping reels, and it never left: reversed cymbals became the whoosh-into-the-downbeat heard on countless records, reversed speech became a horror-film staple, and the reverse-reverb vocal trick โ reverse the vocal, add reverb, reverse again so the reverb SWELLS INTO each word โ remains one of production's most beloved recipes (both halves of it live on this site: echo/reverb next door). The practical uses are quieter: hearing what a suspected backwards message actually says (usually disappointing), and building seamless ambient loops by playing a clip forward-then-reversed so the join always matches โ pair with the looper for that one. A physics note that surprises people: reversed audio keeps its pitch (the frequencies are identical; time's arrow isn't) โ what changes is the ENVELOPE, attacks becoming swells, which is why backwards piano sounds like a bowed instrument. Sound design gold, one click. Export is WAV; the speed changer completes the tape-deck trio.
Frequently asked questions
Does reversing change pitch or quality?
Neither โ frequencies survive reversal untouched, and the operation is sample-perfect: reverse twice and you have the byte-identical original. Only the envelope flips (attacks become swells).
How do I make the reverse-reverb vocal effect?
Reverse the vocal here, run it through the echo tool for a tail, then reverse again โ the tail now swells INTO each word. It's the classic studio recipe, fully doable on this site.
Why does backwards music sound so strange?
Your ear identifies sounds mostly by their attack โ the first milliseconds. Reversal turns attacks into swells, so familiar instruments become unrecognizable while pitch stays the same.
Can I use this to check hidden messages in songs?
Yes โ that's half its traffic, honestly. Expect ambiguity: most 'messages' are the brain finding words in noise (pareidolia), which is its own fun.
