Audio Reverser Online
Play any song, MP3, or voice recording backwards, right in your browser — one click, instant, lossless. Preview, then download the reversed MP3. No sign-up, and your file is never uploaded.
How to Reverse Audio
No account, no upload — three steps on your own device.
Drop Your Audio
Any format — MP3, WAV, M4A, FLAC, OGG, AAC, WEBM, OPUS, mono or stereo, up to 200 MB. It decodes right in the browser.
Reverse It
Hit Reverse Audio. Every sample in every channel is flipped instantly — no wait, no upload, no queue.
Preview & Download
Play the backwards result, scrub the waveform, then download the MP3 at the bitrate you choose — no watermark.
Why Notevibes Audio Reverser
A one-click backwards flip that loses nothing on the way.
One-Click Reverse
No sliders, no settings. Drop your audio, hit Reverse, and the backwards version is ready in a fraction of a second.
Lossless Transform
Reversing just plays the same samples in the opposite order — the flip itself loses nothing. Only the final MP3 encode is lossy, at the bitrate you choose.
Never Uploaded
The reverse runs entirely in your browser. Your file never leaves your device — there is nothing to delete because nothing was sent.
Any Audio Format
MP3, WAV, M4A, FLAC, OGG, AAC, WEBM, and OPUS — mono or stereo, up to 200 MB.
Preview, Then Download
Play the reversed result and scrub the waveform first, then download an MP3 at the bitrate you choose — 64 to 320 kbps.
Free, Anywhere
No watermark, no sign-up, no daily limits. Works on phones, tablets, and laptops in any modern browser.
Nothing to Upload, Nothing to Leak
The reverse happens on your own device. Your file never touches a server — which is a stronger promise than any “we delete it later”.

Every Sound, Played Backwards
Reversing audio is one of the oldest tricks in production — reverse cymbals become eerie swells, flipped vocals turn into ghostly intros, and half the fun of a favorite record is hunting for the message hidden backwards in the bridge. Most sites that do this make you upload the file, sit in a queue, and take a watermark on the way out. This one flips every sample on your own device and hands it back in under a second.
A voice reverser, MP3 reverser, and song reverser in one
Whatever you call the job, this does it. Use it as a voice reverser — record a phrase on your phone, drop it in, and hear yourself backwards. Use it as an MP3 reverser — any MP3 in, the reversed MP3 out. Or use it as a song and sound reverser to play a whole track backwards and hunt for what’s hidden in the mix. Some people call it inverting the audio or playing audio in reverse — same flip, one button.
A flip that loses nothing
Reversing isn’t a filter — it just plays the exact same samples in the opposite order, so the transform itself is mathematically lossless. The only lossy step is the final MP3 encode, and you pick the bitrate from 64 to 320 kbps. Mono or stereo, every channel is reversed in lockstep, and you can preview and scrub the result before you commit.
Private by physics, not by promise
Your file is decoded and re-encoded entirely in the browser — it never reaches a server, so there’s nothing for anyone to store, scan, or forget to delete. It even keeps working if you go offline after the page loads. That’s also why it’s free with no caps: your device does the work, so there’s no compute bill to gate behind a sign-up.
When a reverse is only the first step
Building a reverse effect often means changing more than direction. To flip the speed too — nightcore and slowed edits — use the audio speed changer; to drop or raise the key first, the audio pitch changer. For layering reverse swells into a full arrangement with fades and precise cuts, open the online audio editor.
Need More Than a Reverse?
The full Notevibes editor trims, mixes, adds fades, changes pitch and tempo, and applies AI cleanup — then exports to MP3 or WAV.

Audio Reverser FAQ
Is my file uploaded to a server?
No. The reverser runs entirely in your browser — the file is decoded, flipped, and re-encoded on your own device. Nothing is transmitted, so there is nothing for us to store or delete. You can even go offline after the page loads.
How do I reverse audio online?
Drop your audio onto the reverser, hit Reverse Audio, preview the backwards result, then download the reversed MP3. Everything runs in your browser — no upload, no sign-up, no wait.
Can I reverse an MP3, song, or voice?
Yes — it works as an MP3 reverser, song reverser, and voice reverser in one. Load any sound and it plays back in reverse, then downloads as an MP3. Mono or stereo, both work.
Can I say something backwards with this?
Yes — that's the classic use. Record a phrase with your phone's voice memo app (or the Notevibes voice recorder), drop the file here, and reverse it to hear the backwards version. Learn to imitate the flipped audio, record that, and reverse it again — your 'backwards speech' plays forward. It works as a backwards translator for audio, no typing involved.
Is this a reverse audio search?
It reverses playback — it doesn't identify songs. If you want to know what a piece of audio is, you need a recognition app like Shazam. But if you want to hear audio backwards — to catch a hidden message or build a reverse effect — that's exactly what this does.
What formats can I reverse?
MP3, WAV, M4A, FLAC, OGG, AAC, WEBM, and OPUS up to 200 MB — anything your browser can decode will load. The reversed result downloads as an MP3 at the bitrate you pick, from 64 to 320 kbps.
Does reversing affect audio quality?
The reverse itself is a sample-level operation — the same samples are simply played in the opposite order, so it is mathematically lossless. Only the final MP3 encode is lossy, and you choose the bitrate.
Is the audio reverser free?
Yes — completely. Because the processing runs on your device rather than our servers, there is nothing to meter: no watermark, no sign-up, no daily limits.
Does it work on my phone?
Yes — iOS and Android browsers included. Tap to upload, tap Reverse Audio, preview, download. Long files reverse faster on a laptop simply because the processor is faster.
