Use as an Audio Filter to imprint an (almost) inaudible watermark to your audio. This watermark will get embedded in the audio output. The content of the watermark can be an arbitrary string comprised of 7-bit ASCII characters. I.e. no Unicode at this point, and yeah, no emojis either :-)

Once added, it embeds the message into the audio frequency spectrum as a visible bitmap, pasting the copies of the string back-to-back. When opened in any audio editor that shows spectrograms, it will look like this:

Technically, there are two watermarks, one visible, one invisible, based on a variant of a spread spectrum technique. Should someone wipe the frequency spectrum containing the visible part of the watermark, they won't be able to get rid of the other one. Check out more information on my website. Click on the "More Information" button on the right.

More features can (and will) be implemented. Stay tuned! :-)
BTW, "Antavore" stands for Anti-Tampering Voice Recorder.
