How to reverse audio
- Drop your audio file into the box or choose it. Several files at once work too.
- There's nothing to set: the whole file is reversed straight away. Pick another format under Save as if you need one.
- Play the Result to hear it backwards, then download.
What reversed audio sounds like
Most sounds have a sharp start and a slow tail: a drum hit, a plucked string, a piano note. Reversed, the tail comes first and the sound grows out of nothing before cutting off. Echo and room sound now arrive before the sound that caused them, which gives reversed audio its sucking, dreamlike quality.
Speech turns into something that sounds almost like a language. Vowels survive because they are steady tones, while consonants like “t” and “k” become soft swells, which is why reversed words are so hard to follow.
Creative uses
- Swells into a chorus: reverse a cymbal crash or piano chord to get a rising swoosh that leads into the next section.
- Reverse reverb: reverse a vocal, add reverb in an audio editor, then reverse it again here. The echo now rises up into each word.
- Sound design: reversed voices and footsteps make unsettling effects for games, videos and haunted-house soundtracks. Pair it with change pitch for a deeper, stranger voice.
- The reverse singing game: record a short phrase, reverse it, learn to sing what you hear, record that and reverse it back to see how close you get.
