- Choose MP3 or WAV.
- Press Reverse it and listen to it backwards.
- Download the reversed file.
Why reverse audio?
Producers reverse cymbals, piano chords, and vocal phrases to create swells that rise into a downbeat, one of the oldest tricks in recorded music, heard everywhere from psychedelic rock to modern pop and trap. Reverse a sample and it becomes a brand new sound you can chop and flip. Reverse speech and it turns into an eerie, alien language, useful for horror sound design, game audio, and video transitions.
And then there is backmasking, the idea that songs hide messages you can only hear played backwards. Some artists really did plant reversed vocals on purpose, from the Beatles to Pink Floyd. Most of the famous accidental ones are your brain finding words in noise, especially after someone tells you what to listen for. Now you can check for yourself.
The reverse reverb trick
A classic production move: reverse a vocal phrase, add a long reverb in your editor or DAW, then reverse the result again. The reverb tail now swells up into each word instead of trailing after it, a ghostly build that sounds nothing like normal reverb. Use this page for both reversals and your usual reverb in between.
No quality loss
Reversing only changes the order of the samples, so nothing about the sound is thrown away. Export WAV to keep it lossless. MP3 export is encoded at 320 kbps, which most listeners cannot tell apart from the source. Reverse a file twice and you are back where you started. Very long recordings take more memory to reverse, so for anything over about an hour, cut out the part you need first with our Audio Cutter.
Reverse audio: common questions
How do I play a song backwards?
Drop the song onto this page and press Reverse it. The whole file is flipped from end to start, and you can listen right away in the player. When you like it, download it as MP3 or WAV.
Can I find hidden messages by reversing a song?
You can listen for them. Some artists did hide reversed vocals on purpose, a technique called backmasking. But most famous hidden messages are pareidolia, your brain matching random sounds to words, especially once someone has told you what to hear.
Does reversing audio lose quality?
No. Reversing only changes the order of the samples, so nothing is thrown away. Export WAV to keep it lossless. MP3 export is encoded at 320 kbps, which most listeners cannot tell apart from the original.
How do I make a reverse reverb effect?
Reverse the audio here, add a long reverb in any audio editor or DAW, then reverse the result again on this page. The reverb tail ends up before each sound, swelling into it instead of trailing after it.
Can I reverse a voice memo or voice message from my phone?
Yes. iPhone voice memos are M4A files and WhatsApp voice notes are OPUS files, and both work here. Open this page on your phone or move the file to your computer, drop it in, and download it reversed.
Is my file uploaded?
No. Reversing happens with FFmpeg compiled to WebAssembly, inside your browser tab. Your audio never leaves your device, so we never see, store, or train on it.
