10.0pt;font-family:Arial;color:navy'>FYI, Windows XP has noise reduction, gain
control, and echo cancellation in software for one microphone. You can see
this in operation using Windows Messenger without a headset today. I haven’t
enabled this functionality in ConferenceXP yet because I’m pursuing the
small to medium sized group scenario and the work is non-trivial. I’d be
glad to put someone in touch with the right people inside Microsoft if someone
is interested in looking that this scenario. Unfortunately, the AEC/AGC/NR
functionality is not exposed via an API as it’s built-in to the Windows
Messenger codebase rather monolithicly. They appear as DMO filters using
DirectShow GraphEdit but there are behind-the-scenes initialization methods
needed to get them to work.</span></font></p>

style='font-size:10.0pt;font-family:Arial;color:blue'>I agree that the ASPI EF
400 may not be suited for conference rooms with 3-5 people. Our intent in
trying it out was for PIG systems being used by 1-2 people. For this
purpose the one-mic setup works fine. There's a caveat, however: when the
speakers and microphone are near each other, especially in a confined space,
the EF400 is easily overpowered and can't function effictively. Thus,
it's only effective in a larger space where the speakers can be relatively far
away. We're still looking for a good setup to solve this problem. </span></font></p>

the Regency club - what a difference.. We are testing a new device

headsets from Sennheiser (Modified Pilot headset - bad); Koss; Plantronics and
they were all bad. </span></font></p>
