I have been reading a manual for an AoIP (ravenna) SW sound card. There is
a very interesting comparison between a Mac and a win-pc.
This is not a special card, just a standard GB ethernet card connected to
a Ravenna i/o box (Horus).
Windows:
48K = 64 i/o
96k = 32 i/o
192 = 16 i/o
384 = 8 i/o
latency:
64 samples - not recomended
128 - ok - but not default
256 -recomended
At 192k, smaller buffer sizes are ok, but 64 is minimum (like jack
at 32/2)
Mac:
64 i/o at all sample rates
latency 32/48/64 (defaults to 32)
Is this the hw or the os? the mac gui shows if the computer is running ptp
or not, but the windows one doesn't. maybe that is the difference.
