UltraNet Transmitter

This is the VHDL-logic to transmit 8 individual channels via a single digital transmission line. UltraNet uses an AES3-like connection that contains some Behringer specific channel-status-data. For longer transmission-lines a differential transceiver should be used. Important side-note: even the VHDL-block will take 24-bit audio, UltraNet uses the least-significant two bits to transmit an information for…

Working with multi-channel audio-signals

Todays digital-mixing-consoles are offering high number of audio-channels for processing. I was curious of how modern devices are dealing with realtime digital audio-data and had a look into some of these protocols. I2S, TDM and UltraNet Even if you are not working with professional audio-equipment, at least one of the following systems has been used…
