Reverse Audio
100% private — runs on your device, never uploaded. Works offline once loaded.
Reversing audio is the oldest trick in recorded music and still one of the most useful: reversed cymbals and piano make the swelling sound that pulls a listener into the next section, reversed speech is a staple of sound design, and playing a track backwards is how people check the rumours about their favourite records. Reversing needs every sample of the recording held in memory at once, so it works up to about twenty minutes — trim a longer file first. Run it twice and you get back exactly where you started.
Frequently asked questions
Is there a length limit?
About twenty minutes. Reversing means holding every decoded sample in memory at once, which is what a browser tab runs out of first.
Does reversing lose quality?
Only the small amount any re-encoding costs. Choose WAV or FLAC if you want the reversed copy to be lossless.
Is my file uploaded?
No — it is reversed on your device.
