HDCD Encoding & Burning How ?

[xbox360]

Hello to Everyone, first I would like a detailed small diagram about the diference of Audio CD & HDCD, what software can convert to HDCD Specs & how to burn the file's. Thank You.

Well here's what's listed on Wikipedia: -

translade from somewhere:

"The HDCD (High Definition Compatible Digital®) technology makes it possible to get closer to the original sound. This is facilitated through a sophisticated system, where a 20 - 24 bit sound signal is encoded onto an ordinary CD’s 16 bits through dithering.

When played on a CD player, DVD player or amplifier with an HDCD decoder the sound signal is then decoded again to 20 -24 bits.
The engraver has an extra 6 dB available (7 dB extra at low level), which gives noticeably reduced distortion levels and an extra enhanced resolution. All parameters of the sound image are enhanced, resulting in an all-improved sound! A dynamic range of up to 115 dB can be obtained.
An HDCD equipped device gives even ordinary CDs a high sound quality. The already high resolution sound of DVD audio improves with the HDCD technology. The HDCD circuit is PDM100 (44.1 / 88.2 kHz) and PDM200 (48 / 96 176.4 / 192 kHz) which even can be used with DTS.
The creators of the HDCD technology are Keith O. Johnson and Pflash Pflaumer. Together they developed the idea of HDCD between 1986 and 1991. In 1996 they started Pacific Microsonics (PMI), an audio technology company based in California. In September 2000, (PMI) was acquired by Microsoft.
There are a relatively small number of CDs which have been encoded in HDCD, and a correspondingly small number of players have been sold which are capable of decoding them. However version 9 and above of Windows Media Player running on Microsoft Windows XP is capable of decoding HDCD on personal computers with a 24-bit sound card.
HDCD was an early attempt by audiophiles to improve the sound-quality of CDs, while retaining backward compatibility with existing players. Although new HDCD-encoded CDs are still occasionally added to various catalogs, the format has been largely superseded by newer and more sophisticated digital audio technologies such as Super Audio CD (SACD) and DVD-Audio."

i think that we can join this thread : http://forum.doom9.org/showthread.php?t=118156

i wouldn't say SACD is more sophisticated than even CD-A. it's a step up in sample rate, channels and copy protection, and step backwards in everything else. just another hollow attempt by Sony to sabotage official standards (like DVD-A) and appeal to audiophile fanboys with glossy brochures, specious diagrams and a big whack of placebo.

HDCD sounds compelling (i think Tool do their discs in HDCD? not sure on that), but similar dynamic range can be achieved by psychoacoustic noise-shaped dither in 16 bits. what's more, the information embedded in the bottom 2 bits means dynamic range in regular CD playback is reduced a little.

Who'd 'av thought it ;)
