For an excellent overview of DCC (Philips), including elucidation of
the PASC coding scheme, economics, subjective listener evaluation,
etc., see the series of short articles in the April 91 Stereophile. I
am doing subjective evaluations in experiments with a similar coding
scheme (Musicam) in the digital audio broadcasting domain, and, I must
say, the results are very impressive. Most listeners cannot tell the
difference between an original CD and the PASC encoded version, even
though the latter reduces the bit rate by a factor of 6!
