Super Audio Compact Disc (SACD) Players and Discs
What is a Super Audio Compact Disc (SACD)?: SACD is an optical disc format aimed at high-performance audio playback. SACD was developed by Sony and Philips, the same companies that introduced the CD. SACD players and discs are based on DSD (Direct Stream Digital) processing, a 1-bit format with a sampling rate of 2.8224MHz, 64 times the rate of a standard compact disc. A compact disc is recorded with 16-bits of resolution at a sampling rate of 44.1kHz. The higher sampling rate results in wider frequency response and audio reproduction with more detail. SACD discs have no video content, only audio. Types of SACD Discs: There are three types of Super Audio Compact Discs: Hybrid, Dual-Layer and Single Layer • Hybrid discs have two layers, a higher performance layer that can play only on SACD equipped players and a CD layer that will play on standard CD players. Additionally, some Hybrid SACD discs have both a 5.1 channel surround track and a stereo track.
