Frequently Asked Questions
How do I reverse audio online?
Drop your audio onto the Notevibes Audio Reverser above, hit the Reverse Audio button, then download the reversed MP3. Everything runs entirely in your browser — no upload, no sign-up, no wait.
What formats can I reverse?
MP3, WAV, M4A, FLAC, OGG, AAC, WEBM, and OPUS. Anything your browser can decode with the Web Audio API will load, and the reversed result is exported as a clean 192 kbps MP3. Mono or stereo — both work.
Is it free?
Yes. The Notevibes audio reverser is completely free with no sign-up, no watermark, no ads, and no limit on how many files you can reverse. Max file size is 200 MB.
Is my file uploaded to a server?
No. The reverser runs 100% in your browser using the Web Audio API. Your file never leaves your device — nothing is uploaded, stored, or analyzed. You can even unplug your internet connection after the page loads.
Does reversing affect audio quality?
No — reversing is a sample-level operation. The same audio samples are simply played back in reverse order, so the transform itself is mathematically lossless. The final MP3 export uses a 192 kbps encode, indistinguishable from the original.
Can I reverse a full song?
Yes. You can reverse a complete song up to 200 MB. The entire track is processed instantly in your browser and gives you a downloadable MP3 of the reversed version in under a second.
Why would I reverse audio?
Reversing is a classic creative trick: reverse cymbals and pads produce eerie swells, flipped vocals and melodies create intro and outro effects, and some songs contain hidden messages that only make sense played backwards. It is also the fastest way to build unexpected textures and loops for remixes.
Does it work on mobile?
Yes. It runs on iOS and Android in Chrome, Firefox, Safari, and Edge. Tap to upload a file, tap Reverse Audio, tap Download — that is all it takes.
