A digital interface format that is used to transfer digital audio data between digital audio equipment. Two channels of digital audio (left and right) are carried in one connection. Two protocols based on this format are:
1) S/PDIF (Sony/Phillips Digital Interface Format), used in consumer digital audio equipment such as CD players, DAT recorders, DCC, and MiniDisc recorders. RCA or optical connectors are used.
2) AES/EBU (Audio Engineering Society/ European Broadcasting Union), used in professional digital audio equipment such as PCM and DAT mastering recorders, modular multitrack recorders, digital mixers, and digital audio interfaces for computers. XLR connectors are used.
