Extended Resolution Compact Disc (XRCD) is a mastering and manufacture process patented by JVC (Victor Company of Japan, Ltd) for producing redbook Compact Discs. It was first introduced in 1995.
A XRCD is priced about twice as high as a regular full-priced CD. JVC attributes this to the higher cost of quality mastering and manufacturing.
Technical Overview: The XRCD definition refers to the mastering and manufacture process; the resulting CD and the contained data conforms to the redbook standard and are encoded at 16 bits, 44.1 KHz. Hence, XRCDs are playable on any compact disc player.
JVC uses advanced dither algorithms (though without noise shaping) in their proprietary K2 technology to transfer the analog or digital source to physical disc. The company claims to have studied how inferior CD-remastering techniques degrade the master tape sound and strives to minimize this loss.
