What is an audio reverser?
An audio reverser changes the order of audio samples so a file plays from end to beginning.
Reverse common audio files
The tool accepts formats modern browsers can decode, including MP3, WAV, M4A, OGG, and FLAC.
Browser-based processing
Your file stays on your device. The page decodes and changes the playback order locally instead of uploading it.
Useful for quick sound edits
Make reverse sound effects, backwards voice clips, transitions, or experimental music samples.
What changes when audio plays backwards?
The page changes the order of the decoded audio samples. A sharp attack at the start of a drum hit becomes a tail at the end, while a natural fade-out can become a gradual build-up. Speech keeps the same voices and recording quality, but the words are no longer heard in their original order. Music often reveals reversed transitions, room sound, and instrument decays that are easy to miss during normal playback.
This is a reversal tool rather than a full editor. It does not remove noise, separate vocals, change tempo, or trim a clip. Use the preview to confirm the effect, download the WAV, and then make any timing or volume changes in your preferred audio or video editor.
Before you reverse a file
A few practical details can make the process smoother, especially when you are working with a long recording or a format that behaves differently across browsers.
Start with a common format
MP3 and WAV are the most dependable choices. M4A, OGG, and FLAC usually work too, but decoding support can vary by browser and device. If a file will not open, converting it to MP3 or WAV is a useful first check.
Allow more time for long recordings
Processing happens in your browser, so longer or high-resolution files use more memory and may take a little longer. Keeping the tab open until the preview appears prevents the job from being interrupted.
Expect a WAV download
The finished file is saved as WAV. That format is widely accepted by audio editors, video editors, and converters, and it avoids adding another round of lossy compression before your next edit.

Audio reverser FAQ
Is my audio uploaded to a server?
No. The file is decoded and processed in your browser, so it does not need to be sent to our server.
Which audio formats are supported?
Most common browser-supported audio formats work, including MP3, WAV, M4A, OGG, and FLAC.
What format do downloads use?
Downloads are exported as WAV, which is easy to edit or convert in most audio apps.
Can I use it for songs and voice recordings?
Yes. Songs, spoken clips, field recordings, samples, and sound effects all use the same workflow.
Why does a large file take longer?
Long recordings contain more audio samples, so your device needs more time and memory to prepare the preview.
Does reversing a file remove the original?
No. The original file on your device is not changed. The page creates a separate WAV for download.
Can this tool trim or clean up a recording?
No. It changes playback order only. Trimming, noise removal, and volume adjustment require an audio editor.
