Audio copy protection that protects the 'Analogue Hole'?

http://www.darknoisetechnologies.com/ - I REALLY hope that this doesn't come to be used widely because if used in conjunction with DRM and other digital copy protection schemes, it's very hard (nearly impossible?) to defeat. Sometimes, I wonder if this new 'DarkNoise' thing really works or not. What if you do karaoke and turn off the centre channel? Would that expose this signal? What if companies and offices want to use radio stations (that have DarkNoise without the users knowing) as their 'hold the line' background music?
I want to hear all of your opinions on this... |

1. anti-analog protection? how the fark is that possible? afaik, I can ALWAYS record something i'm listening to whether it's via the speakers or the wave out
2. this thing's gonna be too expensive. 512k encryption? good luck. |

You probably either didn't read the white paper on the technology but, it doesn't involve ANY kind of encryption at all. It just involves using certain types of sounds in the recording itself. This is nothing like previous copy-protection technologies. In fact, if this stuff was used by radio studios and cable TV companies to protect all content being broadcast, you wouldn't be able to record stuff off of those stations for even personal use due to the sound! Think of this as an audio Macrovision -- the thing that was originally supposed to prevent casual VCR-VCR or DVD-VCR (and now, even DBS/Cable-VCR) copying that distorted the picture of the newly recorded tape... |

| theyll be a way roudn it. If the music is playable through a regular CD player + speakers, it will be easy enough to record the stream surely. I doubt they will afford to do it anyway for the time being. interesting read though |

| they did think that the dvd encryption was unbreakable too at one time. We'll have to wait and see what happens if this ever comes to be. I can see audiophiles really being opposed to any technology where you're adding or subtracting anything from the sound. |

That's what I was thinking as I read about it. Who wants extra added into their sound ? The day this becomes common is the day audiophiles revolt. |

Breaking it, through the use of filtration, would be analogous to breaking 512k encryption; just to hack one individual track from one individual CD and such filtration would also damage the original music itself |

Yes. Even digital copy protections sometimes used special sound signals only in the digital signal. This protection fails for LEGITIMATE use on a completely digital system like a CD player with digi-out plugged into a digital receiver/amp and played back with no intention of copying. I've heard these weird sounds before and I bet this DarkNoise thing will be similar, as there will be people with golden ears who'll be able to hear it through a regular non-PC or high quality set-up. |

| I remember they had something like this before. The first time it fails to play or gives out the slightest distortion on any CD player, consumers will start to complain and it will go away. |

| i don't understand this crap. if they are going to put sounds that are undetectable at listening, then it is going to be undetectable at recording. if they put sounds that'll up the recording, then you'll hear it ed up and it'd ruin the music. it is always possible to record it via the wave out. |
