Mainstream digital audio dates from the introduction of the compact disc in the early ’80s, making it about twenty years old. Today two serial interfaces coexist: AES3 (aka AES/EBU) for professional use and S/PDIF for consumer products. Simple low-cost passive conversion between them is possible — even easy — but it is also filled with cautions. The old rule that direct connection between AES/EBU and S/PDIF equipment is bad practice is relaxed today with new receiver chips tolerant to either interface. With that said, let’s explore this tangled nest.
