Digital audio

Digital audio describes sound recording and reproduction systems which work by using a digital representation of the audio waveform.

Digital audio interfaces and interconnects

• AC97 (Audio Codec 1997) interface between Integrated circuits on PC motherboards
• ADAT interface
• AES/EBU interface with XLR connectors
• AES47, Professional AES3 digital audio over Asynchronous Transfer Mode networks
• I2S (Inter-IC sound) interface between Integrated circuits in consumer electronics
• MIDI -- low-bandwidth interconnect for carrying instrument data; cannot carry sound
• S/PDIF, either over coaxial cable or TOSLINK

Audio signals can also be carried losslessly over general-purpose buses such as USB or FireWire.
