Reverse any audio file in one step
Drop a file and it's reversed the instant it finishes decoding — the waveform you see is already the backwards version. Reversal is a pure sample operation (the audio data is rewritten back-to-front), so it's lossless, instant even for long files, and runs entirely in your browser with the Web Audio API.
What people use this for
- Music production — reversed cymbal swells, reverse reverb tails and risers are studio staples. Reverse a crash, layer it before a drop, done.
- Hidden messages & content — the classic "what does it say backwards?" format for shorts and reels.
- Sound design — reversed speech and textures make instant sci-fi ambience.
- Ear training — hearing familiar music backwards is a surprisingly good exercise in active listening.
Reverse a section, not the whole file
Trim the section first, reverse the clip here, then merge it back between the surrounding parts.
FAQ
Does reversing lose any quality?
No — reversing just rewrites the samples in opposite order. Export as WAV for a bit-perfect reversed copy; MP3 re-encodes at 192 kbps.
Why would I reverse audio?
Reversed cymbals and risers are classic production effects, reversed speech is a popular content gimmick, and sound designers use reversal for textures constantly.
Can I reverse just part of a track?
Trim the section with Trim Audio first, reverse it here, then splice it back with Merge Audio.
