RE: " Or WiFi! "

WiFi is just another serialised transport.

Like USB, IEE1394 and Ethernet it packs data into a serial stream. Even SPDIF/AES-EBU, AES-MADI and AES-67/Ravenna are ultimately the same thing.

Some systems are bidirectional on a single link, other are unidirectional. Some include flow control other do not.

But at the bottom we send 16 - 32 Bit Data serialised via some definition and and then decoded.

Both and many other factors too.

Any signal can be degraded sufficiently to cause problems.

This goes into some detail:

At 20 bits, you are on the verge of dynamic range covering fly-farts-at-20-feet to intolerable pain. Really, what more could we need?
