S/PDIF library
S/PDIF library
A software defined S/PDIF library that allows you to trasnmit or receive S/PDIF data via xCORE ports. S/PDIF is a digital data streaming interface. The components in the libary are controlled via C using the XMOS multicore extensions (xC) and provides both a S/PDIF receiver and transmitter.
Features
- Supports stereo S/PDIF receive up to sample rates up to 96KHz
- Supports stereo S/PDIF transmit up to 192KHz
