Cinavia Copyright Protection

Holy shit niggers:

https://en.wikipedia.org/wiki/Cinavia

The watermarking and steganography facility provided by Cinavia is designed to stay within the audio signal and to survive all common forms of audio transfer, including lossy data compression using discrete cosine transform, MP3, DTS, or Ogg Vorbis. It is designed to survive digital and analogue sound recording and reproduction via microphones, direct audio connections and broadcasting, and does so by using audio frequencies within the hearing range. It is monaural and not a multichannel codec.

o Only a single channel of audio is required to detect the watermark
o The watermark is able to survive re-recording through a microphone
o The watermark can be detected through "the production, duplication, distribution, broadcast, and consumer handling of recorded content"
o Different copies of otherwise identical works can be distinguished

Let's brainstorm ways to extract the waveform pattern from this!

What about when it gets implemented in audio cards, and audio chipsets? Where if the audio output device detects a signal of this sort (where "authorized playback" would have modified it or removed it) it will just not play?
What about when it's implemented in the processor firmware? In the firmware of the audio devices themselves?

Then people will just buy non-backstabbing audio cards/chipsets/CPUs? A lot of people are moving away from Intel due to pro-DRM rumors. Intel is getting away with it because they're gigantic, for any other company it would be corporate suicide.

You can play audio on a Microchip PIC32 and a piezo speaker, are they going to backdoor those too? Even in the worst-case scenario where every CPU company has been bribed into backstabbing their customers, with a sufficiently large group-buy you can still get a non-backstabbing CPU produced.
