Frequently asked questions
How does reversing audio work?
Every sound is a series of samples over time; reversing flips their order so the last moment plays first. This tool decodes your file, reverses the samples, and lets you play or download the backwards version.
Is my audio uploaded?
No. The file is decoded and reversed entirely in your browser using the Web Audio API, and the download is generated locally. Nothing is sent to a server.
What format is the download?
An uncompressed 16-bit WAV, which plays everywhere and keeps full quality. It's larger than an MP3 (roughly 10 MB per minute in stereo); convert it afterward if you need a smaller file.
About this tool
The reverse audio tool flips an audio file end to end so it plays backwards. Drop in an MP3, WAV, OGG, or M4A, hear the reversed version, and download it as a WAV. It's used for reveal effects, transition swooshes (a reversed cymbal or piano note), backmasking and hidden-message experiments, and general fun. Decoding, reversing, and export all happen locally in your browser, so the file is never uploaded.
Like most tools on UtilityBase, the reverse audio runs entirely in your browser — nothing you enter is uploaded or stored on a server. It's free to use with no account required. Browse more productivity tools here.
