3.10 S/PDIF Output Connection Header
(Optional)
S/PDIF (Sony/Philips Digital Interface) is a standard audio transfer file format. It is usually
found on digital audio equipment such as a DAT (Digital Audio Tape) machine or audio
processing device. It allows the transfer of audio from one file to another without the
conversion to and from an analog format, which could degrade the signal quality.
