New DVD-Audio music releases and talk about the latest players.

I did find the HDCD patent (#5,479,168)

Extract from patent:

"A fully decoding player, in accordance with the invention, retrieves the control signal and uses it to set up, operate and dynamically change a complementary process to recover the pre-computed high accuracy information and provide low distortion reproduction of the original analog signal. Operations to do this include fast peak expansion, averaged low level gain reductions, selecting complementary interpolation filters, waveform synthesis, and others."

If you read further, there is a whole section on how to do the filter selection on encoding, and filter switching on playback. The section on low level gain control is interesting as well.

If you had any grace at all, I would expect nothing less than an apology from you.
