Avoiding audio feedback

If you're using a microphone with external speakers and a reasonably high gain, you're likely to incur audio feedback problems. To reduce feedback from speakers, Flash Communication Server implements echo suppression. To use echo suppression, use the following command:

myMicrophone.useEchoSuppression(true);

This should maintain a comfortable input level without transmitting too much echo from your speakers.

Because echo suppression removes only a portion of the output signal from the user's input, you might still experience feedback if your microphone is too close to your speaker. To avoid feedback, try following these guidelines:

	Lower your speaker volume.
	Move the microphone and speakers farther apart.
	Troubleshoot your hardware setup for proper installation and settings.
	Use a headset.
