Super Audio CD is the next-generation audio disc format. It has been
jointly developed and standardized by Sony and Phillips of the Nether-
lands which are CD licensers. Compared with the Pulse Code Modula-
tion (PCM) system used for digital audio recording as typified by
conventional CDs, the Super Audio CDs are recorded using the Direct
Stream Digital (DSD) system which has about 4 times more information
per unit time. The system theoretically achieves a dynamic range of 120
dB within the audible frequency band and a wide playback frequency
band that exceeds 100 kHz. It is capable of recording a maximum of 255
programs for up to 109 minutes.
