G'day Andrew


One simply solution I have used in the past, is to use the separate computer 
(ie presenter machine) which has the AG software on it which allows you to 
transmit the desktop or window using VPCScreen, or alternatively, if you VNC to 
the presenter machine, you can then VPCSreen the VNC session.



Given this is a separate machine, you connect the audio output from the 
computer to the Echo Canceller, this then allows you to transmit the audio both 
locally and externally.  I have done this a number of times, especially for 
multimedia presentations.



I hope this gives you an idea for one possible solution.



Cheers,

Jason.

Subject: [AG-TECH] how do I get desktop audio 'into' AG/RAT?



Hi - this is a tough one because of all the echo/feedback problems.

How do sites capture audio from applications on a AG desktop and get it into 
the AG environment?

For example, if I want to share desktop multimedia I can use VPCScreenProducer 
to inject the video into VIC.
But what do I do about audio? the normal audio-out is echo cancelled by the 
ClearOne or similar device so isn't transmitted into RAT.

One idea, that I haven't tried, is to use a second sound device and feed it 
into the ClearOne or room to be picked up by the line/mic-in on the primary 
card (where RAT is recording)? But then I have the hassle of figuring how to 
tell particular apps to use device 2 rather than device 1 for audio.

My application is with Linux (FC) desktops, but the same problem would apply to 
Windows & OS X.

Any advice would be welcome.

Cheers, Andrew
