Title: how to reduce echo of microphone in flex
I'm trying to build a video chat program using Adobe Flex but there is a giant problem with echos. If the participants arn't using headsets, everything they say echos. Worse, they can actually create positive feedback loop of echos that won't end until the mics are muted.
Has anyone found a solution for this on the Flex/Flash platform?
My software is using the Speex code

Right click on flash movie and select settings. In the Flash Player Settings Window click on the mic tab and select Reduce Echo option.
or
you can use the setUseEchoSuppression in actionscript code .

var myMic:Microphone = Microphone.getMicrophone(0);
myMic.setUseEchoSuppression(true);

reducing the mic volume and also disabling the mic boost is also helpfull in reducing the echo. Mic boost in in advanced settings of system volume.

with speakers there will be a lot of echo , unfortunately there is no proper solution to overcome this kind of echo with flash player. its better to use headphones instead to avoid feedback audio. The above solutions mentioned by troy and caldwell should help to some extent.

Acoustic Echo Cancellation is not possible with flash player. ADOBE is very bad on this. A long awaited feature.
You can control the Microphone volume using following code. Value can be from 0 to 100.
my_mic.setGain(50);
Boost cannot be controlled using actionscript.
