About this launch

Audio Reverser is a free online tool that reverses audio files directly in your web browser. Upload MP3, WAV, M4A, OGG, or FLAC files and listen to the reversed version before downloading it as WAV. All processing happens locally on your device—nothing is sent to a server.
The tool changes the playback order of audio samples so files play from end to beginning. It works with songs, voice recordings, field recordings, samples, and sound effects. Use it to create reverse sound effects, backwards voice clips, transitions, or experimental music samples.
Audio Reverser is designed for quick backwards audio tests and edits. It does not trim, clean up, remove noise, separate vocals, or change tempo—use your preferred audio editor for those adjustments. Download the reversed WAV file and edit further in any audio or video editor.
