Hi George/Joseph, I have build a Cam/Mic testing application where you can compare the settings between AEC and not having AEC in OpenMeetings.
I could not find any difference, however I also have quite good headsets and a good microphone with build in echo cancellation on MacBookPro. Please see this description on howto install/test AEC feature with the testing application: https://cwiki.apache.org/confluence/display/OPENMEETINGS/Camera+Micro+Testing+Application+Standalone Basically you simply copy: https://svn.apache.org/repos/asf/incubator/openmeetings/trunk/singlewebapp/WebContent/src/test/test-setup.lzx.swf11.swf To: $RED5_HOME/webapps/openmeetings/ a) Then navigate with your browser to: http://localhost:5080/openmeetings/test-setup.lzx.swf11.swf b) Input IP/Host on the top => click connect c) Choose streamname to broadcast => share Open a second browser on another machine: a) navigate with your browser to to the same app. b) Input IP/Host on the top => click connect c) Choose streamname to play (Has to MATCH the one in the broadcast of course!) => play This works of course also vice-versa. So you can make a simple 1:1 chat. To change settings it is best to press F5 and reload the browser and reconnect.
