High Definition Compatible Digital (HDCD) is a family of sophisticated technologies that improve the quality of all forms of digital audio recording and playback- including Compact Disc and DVD-Audio-by increasing resolution and reducing distortion that occurs during analog-to-digital (A/D) and digital-to-analog (D/A) conversion, digital processing and digital filtering.
Following are the primary benefits of HDCD technology:
HDCD-encoded recordings sound better on all digital player products because HDCD subtractive dither A/D conversion and dynamic-filter processes yield a higher resolution, lower distortion, signal. For HDCD Compact Disc releases, Peak Extend restorable soft limiting can increase resolution by allowing signal levels to be raised by up to 6 dB, Low Level Extend can improve resolution of low- level signals, and HDCD high-frequency dither improves resolution by 6 dB (one bit).

HDCD-equipped players improve the sound of all digital recordings because HDCD decoding includes the HDCD precision up-sampling digital filter.
When played on a player with HDCD decoding, HDCD Compact Disc recordings have set a new standard for audio fidelity in the home because, on top of delivering all the benefits mentioned above, HDCD decoding restores encoded peaks and low-level information, resulting in a signal with 20 bits of real musical information instead of the 16 bits of all
The professional Model Two HDCD processor is designed for DVD, DVD-Audio, and CD mastering, mixing, and tracking. The Model Two features two channels of HDCD A/D conversion, D/A conversion, and digital processing at 192 kHz, 176.4-kHz, 96-kHz, 88.2-kHz, 48-kHz, and 44.1-kHz sampling rates and 24-bit, 20-bit, and 16-bit word lengths.
The Model Two is designed for surround sound, with a Master mode that allows multiple Model Two units to run from a single precision clock. That makes the Model Two a master word sync generator, allowing A/D and D/A conversion to be directly clocked from a precision internal reference. Resolution and accuracy are unmatched, with distortion products below -120 dB..
