Frequently Asked Questions

Is my audio file uploaded to a server?

No. All processing happens 100% in your browser using the Web Audio API. Your file never leaves your device, ensuring complete privacy and security.

What does reversing audio do?

Every sample of the audio is played in the opposite order, so the whole clip sounds backward from end to start.

What format is the output?

The reversed audio is exported as an uncompressed PCM 16-bit WAV file at the same sample rate as the original.

Can I reverse long recordings?

Yes, but very long files use more memory. For best results keep clips under a few minutes.
