Why Reverse Audio
Playing a sound backwards is one of the oldest tricks in music and one of the most fun things to do with your own voice. Yet most media players cannot do it, and audio editors bury it in a menu after an install. An online reverse audio maker does it in a click, records your voice if you need it and lets you hear the result straight away, on a laptop or a phone, without an account.
- Media players and phones have no button to play audio backwards.
- The reverse singing challenge needs a recording reversed, then reversed again.
- Checking a rumored hidden message means reversing just a few seconds of a song.
- Reverse reverb swells and risers take a full editor and a lot of clicks.
- Apps full of ads, or uploads to a stranger’s server, are not worth it for a quick laugh.

Features of the EzTranscriber Reverse Audio Tool
For creators, producers, sound designers and anyone curious about what a sound hides.
A Reverse Voice Recorder for Backwards Speech
Press record, say a sentence and hear it backwards a moment later. The reverse voice recorder captures your microphone in the browser, so it doubles as a reverse audio recorder, a backwards voice recorder, a reverse sound recorder and a backwards audio recorder with nothing to install. Think of it as a reverse recorder that hands you both versions of every take. Reversed speech sounds strangely familiar: vowels stay recognisable while every word turns into new syllables, which is why people use it as a reverse speech generator, a backwards speech generator or a reverse voice generator for jokes, puzzles and eerie game dialogue, and children love it as a backwards voice generator for their own names. Use it as a voice reverser online, then download the reverse voice recording to share.
Record and ReverseThe Reverse Singing Challenge, Step by Step
The challenge is simple and always funny. Record a short line of a song, up to eight seconds, play it backwards, slow it down if you need to, then record yourself copying the backwards version as closely as you can. Reverse that second take and you will hear the original line again, a little bent out of shape. This reverse singing website guides you through all four steps, gives your copy a rhythm match score just for fun and keeps every clip side by side, so you can play them in turn and decide who copied best, then download the clips for your video.
Start the ChallengeReverse a Song or Just a Selection
Want to play a song backwards? Drop it in and the song reverser flips the whole file, or drag across the waveform to reverse only the chorus, a riff or a single word; the edges of the selection are crossfaded so the join stays smooth. Rumors of hidden backwards messages, known as backmasking, are easy to check this way: select the few seconds in question and listen. It works as a reverse song player and a reverse music player in one, and you can reverse MP3 online or start from WAV, M4A, FLAC or OGG.
Reverse a SongReverse Audio Effects for Sound Design
Producers have used backwards audio for decades. Reverse a crash cymbal or a piano chord with a long tail and the decay becomes a swell that rises into the next bar; reverse a vocal with its reverb and you get the ghostly reverse reverb heard on countless records. As a reverse audio effect it is quick to audition: reverse a selection, loop it, and download the reverse sounds as WAV for your project. Reversing music like this is lossless, because the samples simply play in the opposite order.

Want your own voice backwards? Record or drop a file into the tool above.
A sound with a sharp start and a long fade, such as a piano chord in a big room, turns into a slow swell that ends with a sudden hit when reversed. That is the reverse reverb trick, and it is exactly what the reverse audio tool above does to your own files.

Reverse Audio FAQs
Quick answers about reversing songs, voices and sound effects.
How do I reverse audio?
Drop a file into the tool at the top of this page, or record up to five minutes of your voice, and it plays backwards straight away. Reverse the whole clip or a selection, then download the reversed audio as WAV or MP3.
How do I play a song backwards?
Drop the song in and press play on the reversed version. To hear only part of it, drag across the waveform and reverse just that selection.
How do I reverse my voice?
Press record, speak or sing, then stop. Your reverse recording plays straight away and can be downloaded, which makes this a reverse voice recorder free to use as often as you like.
How does the reverse singing challenge work?
Record a line, reverse it, record yourself copying the backwards version, then reverse your copy. If you copied well, you will hear something close to the original line.
Can I reverse only part of an audio file?
Yes. Drag across the waveform to select a word, a beat or a chorus, and only that selection is reversed; the rest plays as normal.
Is this easier than Audacity?
If you only want to reverse audio, Audacity is more than you need: there you install it, select the clip and choose Effect, then Reverse. Here you drop the file in or press record, and the reversed version is ready.
Does reversing audio lose quality?
No. Reversing only changes the order of the samples. A WAV download keeps every detail; MP3 is smaller with a little compression.
Which files can I reverse?
Any reverse audio file your browser can open: MP3, WAV, M4A, AAC, FLAC, OGG and the soundtrack of MP4 and MOV videos, up to 200 MB and 15 minutes. Downloads are WAV or MP3.
Can I reverse audio on my iPhone or Android phone?
Yes. Open this reverse audio website in your mobile browser, record or pick a file and download the result, with no app to install.
Can I hear hidden messages in songs?
You can check the claims yourself: select the few seconds in question, reverse them and loop them. Most rumored messages turn out to be the brain finding words in random syllables, which is half the fun.
Why does reversed speech sound like another language?
Speech is built from short sounds that change shape over time. Played backwards, vowels still sound like vowels, but consonants such as p, t and k swell up instead of snapping, and syllables come out in a new order. Your brain hears familiar sounds in unfamiliar patterns, so it feels like a foreign language you almost understand.
Can I slow down or speed up the reversed audio?
Yes. The speed control runs from 0.5x to 1.5x and works like a tape: slower is lower and faster is higher, for playback and the download. To change the speed but keep the pitch, download the reversed version and open the BPM changer, or try the slowed reverb generator for a dreamy backwards effect.
Can I change my voice as well?
Yes. Download the reversed take and run it through the voice changer for a deep, robotic or alien reverse voice changer effect.
Is it free, and are my recordings uploaded?
It is a way to reverse audio online free of charge, with no sign-in, and everything runs in your browser, so your songs and recordings never leave your device.
