Summary

S/PDIF (Sony/Philips Digital Interface) is a standard for transmitting digital audio signals over relatively short distances between devices. It was developed by Sony and Philips and is used to carry high-quality digital audio without the need for analog conversion, maintaining the integrity of the audio signal.

S/PDIF can carry two channels of uncompressed PCM (Pulse Code Modulation) audio or over Optical (TOSLINK) or Coaxial transmission mediums.

lib_spdif provides software defined S/PDIF implementation that allows transmission and reception of S/PDIF data via xcore ports.
