About LPCD

SACD (Super Audio Compact Disc 縮寫) 是由Sony及飛利浦兩家公司所訂定的音源儲存規格，於1999年創立，希望作為新一代數位音樂格式的標準。與SACD競爭的技術有DVD Audio。

XRCD = Extended Resolution Compact Disc:

XRCD (short for eXtended Resolution Compact Disc) is a special mastering and manufacture process patented by JVC that is used for producing high fidelity redbook Compact Discs. It was first introduced in 1995.

Overview
XRCDs are in every aspect regular CDs that just have been manufactured to stringent quality standards. This means that they can be played on any conventional compact disc player. It is interesting to note that an XRCD is supposedly priced about twice as high as a regular full-priced CD. JVC attributes this to the high cost of the quality mastering and manufacturing process.

Mastering process

If digital, the source material is first converted to analogue with a K2 20-bit or 24-bit digital-to-analog converter. The signal is then digitized with JVC's K2 analog-to-digital converters. This musical information is next encoded on a magneto-optical disk for transportation.

The disk is sent to JVC's Yokohama manufacturing plant, where after reducing jitter and distortion the musical signal is down-converted to 16-bit through a K2 "super coding" process. This 16-bit signal is then EFM-encoded before going through a high-precision DVD K2 laser using a proprietary "Extended Pit Cut" technology. This optimizes the linear velocity of the glass master (giving precise pit lengths), as well as eliminating any time jitters, all the while controlled by an extremely accurate Rubidium clock. All CDs are then stamped directly from the glass master.

XRCD2 and XRCD24 are improved versions of the original XRCD process. XRCD2 is the first to record to a magneto-optical disk via the digital K2 regenerator. XRCD24 upgraded the transported music signal's bit width from 20 to 24 bits.

LPCD技術,既保留了數碼錄音背景清晰幹凈的優點,又承傳了模擬錄音富有樂感的特點。可以預料,這樣的唱片推出後不僅會受客家人的歡迎,也會得到音響發燒友的喜愛


LPCD is a kind of cd, you can play it by normal cd player
