Frequently Asked Questions

How do I reverse an audio file?
Drop your audio file onto the page (or click to browse), wait a moment while it decodes, then press Play Reversed to preview the backwards version. Click Download WAV to save it.
What file formats can I reverse?
Any format your browser can decode — MP3, WAV, OGG, FLAC, AAC, M4A, and others. The tool uses the Web Audio API, which supports the same formats your browser plays natively.
Is my audio uploaded to a server?
No. All audio processing happens entirely in your browser using the Web Audio API. Your files never leave your device. See our privacy policy for details.
What format is the downloaded file?
The reversed audio is exported as a WAV file (16-bit PCM, same sample rate as the input). WAV is lossless, so the export does not introduce additional compression. You can convert it to MP3 or another format using any audio converter.
Does it work on mobile?
Yes. The page is fully responsive and the Web Audio API works on modern iOS and Android browsers. Processing time depends on your device.
Is there a file size limit?
There is no hard limit imposed by SnipSound. The effective limit is your device's available memory — reversing very long files (over an hour) on a low-memory device may be slow.
