Audio Reverse
Free online audio reverse tool. Play any audio backwards directly in your browser. 100% private, no upload, supports MP3 WAV OGG FLAC and more.
How does audio reversing work?
Audio reversing reads the audio data samples and plays them in reverse order from end to start. This creates a backward version of the original sound where every waveform is flipped horizontally.
What audio formats are supported?
The tool supports all major audio formats including MP3, WAV, OGG, FLAC, M4A, AAC, WMA, and WebM. The reversed audio is exported as high-quality WAV to preserve full fidelity.
Is my audio data uploaded to a server?
No, all audio processing happens entirely in your browser using the Web Audio API. Your files never leave your device, ensuring 100% privacy and data security.
Why is the reversed audio downloaded as WAV?
WAV is a lossless format that preserves the full quality of the reversed audio without any compression artifacts. This ensures the output maintains the same audio quality as the input.
Can I reverse long audio files?
Yes, the tool can handle audio files of various lengths. Processing speed depends on the file size and your device's performance. Large files are processed efficiently using streaming techniques.
Does the tool work offline?
Once the page is loaded, the audio processing works completely offline. You only need an internet connection to initially load the tool page.
What are common uses for audio reversing?
Audio reversing is used for music production (creating special effects), finding hidden messages or backwards masking, audio analysis and forensics, creating sound art, and educational purposes.
Will the reversed audio sound different in quality?
No, the reversed audio maintains the exact same quality as the original. Only the playback direction changes — the sample rate, bit depth, and channel count remain identical.
Can I preview the reversed audio before downloading?
Yes, you can preview the reversed audio directly in the browser before downloading. This lets you verify the result meets your expectations.
Is this tool free to use?
Yes, the tool is completely free with no registration required. There are no file size limits or usage restrictions.
Does reversing audio work with stereo files?
Yes, both left and right channels are independently reversed, maintaining the stereo image of the original recording.
What browsers are supported?
