[WT-support] W8?

[Tõnno Vähk]

Thanks guys,

I understand from the silence of others that I can conclude that W8 with
classic shell should be at least as good as W7 and no reason to avoid it so
I will probably install it on all the station computers (no internal sound
card used for voice keyer)...

Latency comes down to two items - 1) does the sound card have hardware
(analog) monitoring capability (those that do will generally show a
"microphone" control on the "Levels" tab for the output device in Windows
Sound Control Panel) and 2) Will Vista/Windows 7/Windows 8 allow you to
access/control it.

For devices that lack a hardware monitor, it is possible to minimize latency
by careful choice of sample rates *and* data formats for the sound card
microphone.  Lower sample rates, lower numbers of bits (8 vs 16 vs. 24), and
less compression will all reduce latency when the monitor must be done via
digital loop (no hardware monitor or monitoring on a separate sound card).
Careful parameter adjustment and attention to software priority can often
get the monitor latency below 100 ms which is, in most cases, low enough as
to not be a problem.
