HDCD : High Definition-Compatible CD. A trademark dithering process by Pacific Microsonics. The "HDCD process effectively cancels the additive distortions and simultaneously provides additional data to reduce the subtractive distortions" and is compatible with existing consumer digital playback equipment, claiming that there is a clear improvement in the fidelity of the conventional CD. The process works by converting an analog signal into a digital signal with a word length of "longer than 16 bits" and at a sampling frequency of "greater than 100kHz." These data can then be encoded into the standard CD format, or used with 20- or 24-bit recording/editing hardware/software. When used with an HDCD decoder, the reconstructed signal is output at the appropriate > 16-bit, > 44.1kHz format."
