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 Media Server uses echo suppression, which you can implement by using the following command:

my_mic.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.
