SACD
Short for Super Audio Compact Disc. SACD is a high-resolution consumer digital audio format that uses DSD (Direct Stream Digital) technology. DSD uses a 1-bit 2.8 MHz sampling rate for digital conversion. A hybrid SACD can store the hi-res stereo and 5.1 surround version of an album, as well as the standard 44.1 kHz/16-bit version (which any CD player can play). The SACD spec also makes room for images and video clips. At the high end of hi-res consumer digital audio, SACD competes wth DVD-A.
