About the Super Audio CD
Super Audio CD is a new high-quality audio disc
standard where music is recorded in the DSD (Direct
Stream Digital) format (conventional CDs are
recorded in the PCM format). The DSD format, using
a sampling frequency 64 times higher than that of a
conventional CD, and with 1-bit quantization,
achieves both a wide frequency range and a wide
dynamic range across the audible frequency range,
and so provides music reproduction extremely faithful
to the original sound.
