HDCD

(High Definition Compatible Digital) A digital processing technique that increases fidelity on audio CDs, developed by Keith Johnson and Michael "Pflash" Pflaumer. HDCD uses a 20-bit master instead of 16 bits and stores the additional data in a subchannel that is processed on HDCD-equipped players. The format remains compatible with the traditional audio CD, and non-HDCD players can play HDCD discs as if they were regular CDs. Because HDCD players have a higher quality digital filter, regular CDs may sound better.

Sold to Microsoft
Johnson, a recording engineer, and Pflaumer, inventor of the local area network TOPS, founded Pacific Microsonics, Inc. in 1996 to license the HDCD technology. In 2000, Microsoft acquired PMI to boost its strength in digital media, and the HDCD codec was later added to Windows Media Player, making it the first software player to support it. There are thousands of HDCD titles and numerous HDCD CD players on the market.

After some thought, I am obliged to list the reissue of the famous Proprius recording, Jazz At The Pawnshop, for the second year in a row, now that it's available in the SACD format (FIM SACDM 034, hybrid HDCD, with both stereo and multi-channel SACD segments).
As it has been demonstrated to me time and again, the most notable improvement you'll find on this SACD when you compare it to the standard PCM recordings (in either XRCD or HDCD) is stage width, height and imaging.
Although not quite as widespread as Microsoft's HDCD encoding, JVC's K2 process has an advantage over HDCD in that it does not require a CD player that can decode their recordings for optimum sound.
But all things being equal, the higher resolution that results from any of the advancements in the digital audio format (whether they are remastered in SBM, XRCD, HDCD, DVD-audio or SACD) theoretically should provide the listener with sound more closely approaching that of the original source.
Then review the new formats (DVDA, SACD, HDCD, XRCD, etc.) and whether in your opinion they are worth considering.
Please note that HDCD and XRCD are essentially mastering technologies, the first of which requires an HDCD player for maximum resolution, the latter not needing any special hardware.
(All of this without HDCD decoding at my end of the recording chain, by the way.)
This is a sensational recording, even without HDCD decoding.
Soon, the expected opening up of the market for high-density compact discs (HDCDs) will create new business and require disc replicators to establish new quality/productivity parameters.
Before video CD can really be viable, HDCDs will have to become commonplace.
When HDCDs finally hit the market, will replicators have to buy new production machinery?
But it may still be difficult for facilities geared to short-cycle, low-tonnage CD audio production to produce HDCDs on the same equipment.
