iii) You need to come up with a quantitative requirement for jitter and
relative latency and justify it. I saw the figure of 10us mentioned on
the Yahoo mailing list. This is ridiculously tight. An 802.3 voter who
is experienced in VOIP pointed out to me that even 1ms is too tight when
you consider that sound only travels one foot in a millisecond. Once you
have this requirement nailed a lot else will fall into place.
However, the requirements for
(a) performers listening over headphones to a mix that includes their own voice and
(b) forming a stereo or surround image from speakers that are individually (and independently) connected to the network
are more stringent than those for voice telephony.
