An audio reverser plays back sound in the opposite direction — from the last sample to the first. This creates a distinctive backwards effect used widely in music production, sound design, podcasting, and creative projects.
This tool uses the Web Audio API built into all modern browsers to decode your audio file, reverse the raw audio samples in memory, and encode the result as a downloadable WAV file — entirely without a server.
Your audio file never leaves your device. All reversal happens locally in your browser.
The reversed audio is saved as an uncompressed PCM WAV file for maximum quality.
Stereo and mono audio are both supported. Each channel is reversed independently.
Listen to the reversed audio before downloading to make sure it's what you need.
The tool supports MP3, WAV, OGG, FLAC, AAC, and most other common audio formats that your browser's Web Audio API can decode.
No. Your audio file never leaves your device. All processing happens entirely in your browser using the Web Audio API.
The reversed audio is downloaded as a WAV file, which preserves full audio quality without any compression.
There is no strict limit, but very large files (over 100MB) may require more time and memory. We recommend files under 50MB for the best experience.
