Reverse audio plays a recording from its end back to its beginning. A drum hit becomes a swelling lead-in, a spoken phrase sounds unfamiliar, and a short melody takes on a different shape. This page gives you a quick way to make that change, compare it with the original, and keep a WAV copy. The tool above is ready immediately; the notes below help you choose a good source and understand what you hear.
Start with a file or a fresh recording
Choose an audio file that your browser can play, upload a short video with sound, or use Record audio to capture a new clip. A video contributes its sound only; the picture is not reversed or downloaded. Try a clear, short clip first: one spoken sentence, a hand clap, a tap on a table, or a few notes. Short examples make the change easy to recognize and are faster to compare. You can also drop a file onto the page. If a file does not load, try a common format supported by your browser or make a brief recording instead.
For a phone recording, bring the microphone close enough to hear the subject without putting it directly against a loud speaker. Record a few seconds, stop, and listen to the original player before judging the reversed result. The two players are useful for separating a recording problem from a reversal problem: noise that is already in the original will also be present when its timeline runs backwards.
Compare original and reversed audio
After the file loads, play Original and then Reversed. The reversed version changes the order of the sound over time. It does not translate words, remove background noise, or create a new performance. If you reverse a song, you are hearing the same recording from the last sample toward the first. Pauses, reverb tails, and sudden attacks therefore appear in different places.
Listen for the beginning and ending of each event rather than trying to identify every word. A clap is a useful example: its sharp attack happens first in the original, while the quieter decay comes first in the reversed version. With speech, consonants and breath sounds move into unfamiliar positions. With music, a note's fading tail can sound like it is rising into the note. Use the two players to switch back and forth as often as you like.
The same sound can feel different when its order is reversed. This illustration is a visual example, not a waveform from your private recording.
What can you use reverse audio for?
Sound experiments. Reverse a clap, a snap, a door closing, or a short drum hit to hear how an attack and a fade trade places. These small sounds are easy to record yourself and let you notice the effect quickly. Start with one isolated sound instead of a busy mix so you can tell what changed.
Creative editing ideas. A reversed cymbal or piano note can suggest a transition into the next moment of a video or music project. Download the WAV file and bring it into your editor if you want to trim it, mix it with other tracks, or add effects. This page reverses the audio; it does not provide a multitrack editor or generate a separate reverse-reverb effect.
Speech and listening games. Record a familiar phrase, play it backwards, and ask a friend to guess what the original was. Some sounds may seem like other words by coincidence. Treat that as a listening game, not as a reliable way to discover a hidden message. Comparing with the original helps you hear exactly which sounds produced the effect.
Reverse singing. Open the separate reverse singing mode above after adding a clip. It plays a reversed source while recording your attempt, then reverses your attempt back for comparison. Use headphones so the source does not spill from the speaker into the microphone. A short phrase is much easier to imitate than a whole song, and you can repeat the experiment without changing the original file.
Record clean audio before you reverse it
Reversing audio preserves what the microphone captured, including hiss, room echo, clipping, and music playing from another device. If your recording sounds uneven, check the original player first. Try a quiet room, move away from fans and traffic, and keep the phone steady. A sudden loud sound very close to the microphone may overload it and cause distortion that remains audible in both versions.
If you are recording sound from another phone, lower the playback volume or move the recording phone a little farther away. Playing music through speakers while recording with the same device can create feedback or echo, depending on the phone and browser. For reverse singing, headphones are especially helpful because the microphone then hears your voice more clearly than the guide clip. The level hint beside your recording is only an estimate of its peak; it cannot diagnose every kind of noise or echo.
Made a mistake? Select Record again after your first recording, capture a new take, and compare the updated result. If you prefer, you can choose a file instead. Your current source is replaced when you load another one, so download any result you want to keep before starting over.
Files, downloads, and privacy
This free reverse audio tool runs in your browser. It does not ask you to create an account, and the audio processing happens on your device rather than by uploading your clip to our server. Browser support still matters: a file must be playable and decodable by the browser on your phone or computer. If one format fails, convert it locally to a format your browser supports or try a short recording made with the page.
The download button saves the reversed result as a WAV file. WAV is widely accepted by audio and video editors, but it can be larger than a compressed music file. The tool does not currently export MP3, remove vocals, normalize a quiet recording, or clean up microphone noise. If you need any of those changes, download the WAV and continue in an editor that supports them.
Closing or refreshing the page clears the working audio from this browser session. Keep a copy of the original file yourself and download the reversed file if you want to use it later. When working with someone else's song, speech, or recording, check that you have permission before sharing or publishing the edited audio.
Frequently asked questions about reverse audio
How do I reverse a voice recording?
Use Record audio above, speak a short phrase, and stop recording. Listen to Original to check its quality, then play Reversed. You can record again if the first take is too quiet or noisy.
Can I reverse a song or a longer clip?
You can choose an audio file your browser can decode. Large or long files take more memory and may process more slowly, especially on a phone. For a first test, use a short excerpt that you have the right to use.
Can I upload a video to reverse its audio?
Yes. Choose an MP4, MOV, or WebM with an audio track. This tool extracts the sound in your browser and lets you listen to or download it backwards as a WAV file. It does not reverse or export the video picture. Videos over 30 MB or 5 minutes are not supported; some audio codecs may also depend on your browser.
Why does my reversed recording sound quiet or distorted?
Listen to the original track. If it is already quiet, clipped, or echoing, reversing the order will not repair it. Record again in a quieter place, avoid a very loud nearby speaker, and use headphones for the singing mode.
Does reverse audio reveal hidden words?
It can produce sounds that resemble words, but that resemblance is subjective. This tool reverses the playback order; it does not analyze speech or verify hidden messages. Compare the original and reversed versions before drawing a conclusion.
