Protocol section says that 20 bit audio samples are standard. Well perhaps this has come from SD-SDI television standards where standard AES audio packets are limited to 20 bit audio. Extended Data Packets can follow standard 20bit audio packets in SD-SDI - these contain an extra four AES auxiliary bits which can be used for 24bit audio.

In HD-SDI (and better) Audio Data Packets are 24bit as standard. Of course, the four least significant bits will be zero padded if presented with a 20bit PCM source.

Protocol section says that 20 bit data is normally used. Where does this come from? I believe 16, 20 and 24 bit depths are all quite common these days. --Kvng (talk) 15:57, 29 December 2010 (UTC)

re: "20 bit is normally used." Agree this is a dubious proposition. We are talking about the professional interface standard here - not consumer stuff, correct? Well, by way debunking the "...20 bit..." assertion, Avid's ProTools makes no provision for CREATING 20 bit sessions. It doesn't even acknowledge the 20 bit session format other than for file imports - wherein it converts them to either 16 or 24 (or 32 floating in PT10 and later). That is certainly not conclusive, but I find it hard to believe that one the dominant DAW platforms in the world today doesn't even provide for creating 20 bit files if they are "normally used". Again, anecdotal, but I've been doing digital audio since 1982 as a full time audio professional in the recording industry, and I've never elected to output a 20 bit file format (yet :) I'd be interested in hearing others' comments. Who is using 20 bit anymore? I am always willing to learn and grow, but it looks to me like the whole "20 bit" thing was no more than a brief flirtation back in the 90's and early 2000's. That was when storage space concerns made adoption of 24 bit file formats a perilous and expensive proposition. That era is over. Perhaps it is time to state the obvious here on the wiki.

Major editing, pictures added

I just reworked the article lead in and edited the "Hardware connections" section, adding pictures, attempting to unify some of the article prose and include some more citations. I welcome your suggestions/criticism.Ke6jjj (talk) 23:52, 7 January 2014 (UTC)

Physical interconnection types

Dp Kundu has boldly changed this to call out balanced XLR and unbalanced coax. POF and RCA were removed. I assume the justification for this is because POF and RCA are S/PDIF, not AES3. Dp Kundu's edit comment just says, "Correcting incorrect information abt AES3 connection types." ~Kvng (talk) 16:30, 6 June 2019 (UTC)
