  Description     : commandline tool for audio watermarking

Audiowmark is an Open Source (GPL) solution for audio watermarking.

Audio watermarking is the process of adding a message to the sound that
is undetectable to the human ear. It is one way to prove authorship of
the marked content.

This tool allows to embed an inaudible 128-bit message in media files in
a robust and secure way. It uses forward error correction to ensure that
even a damaged watermark can still be decoded, so the watermark survives
lossy compression (mp3/ogg).

Informal listening tests were conducted, almost all users do not
perceive the difference between original and watermarked signal.

Audiowmark can also be used when live when streaming content a watermark
can be added to the audio on-the-fly.

Hi Robin,

It's currently available in both unstable and testing, so I'm closing this RFP.

Would a backport to trixie-backports be useful to you?

I can probably package this too; if you are interested can you create a separate RFP and CC me?


Cheers!

Chris
