I just posted the article ‘Hi-fi nuking’ CD technology safe claims developer.

The audio protection Cactus Datashield does not damage your hifi equipment according to an article on the Register.

Earlier we reported about an article in the NewScientist that reported…

Just a thought, but, If the if the protection adds <snip> bursts of noise <snip> and the <snip> the noise is eliminated by a conventional CD player’s error correction system,<snip> If you made a 1-1 copy wouldn’t the conventional CD player’s error correction system correct the noise?:stuck_out_tongue:

Dosen’t really matter since u can make a 1:1 copy with CloneCD (subchannel data from Audio Tracks)

Someone needs to make a type of DirectX Plug-in that would process the audio just as a pass through the normalization process occurs in Audiograbber - the Plug-in would error-correct the audio just as the "conventional cd player’’ does. In the Audio world of Sound Forge or Wavelab there are plugins to affect the audio in every possible way from correcting a singers bad note to Dc Offset to adding Echo. These plugins interpret the audio & spit back out the processed audio - let’s just do that with error correction. I think it is call BER or something like that. Minor errors can be interpolated – “made up” based on the evidence of surrounding samples Read this: http://www.geffers.demon.co.uk/cd.html

The copy protection these guys are using depends on the Redd-Solomon arror correction for proper playback in “conventional” cd players. Here is lots of technical stuff on it - from this info we should have a plug-in for EAC in a day or 2…yes?
