Flash Player 6.
activeMicrophone.setUseEchoSuppression(suppress)
suppress A Boolean value indicating whether echo suppression should be used (true) or not (false).
Nothing.
Method; specifies whether to use the echo suppression feature of the audio codec. The default value is false unless the user has selected Reduce Echo in the Flash Player Microphone Settings panel.
Echo suppression is an effort to reduce the effects of audio feedback, which is caused when sound going out the speaker is picked up by the microphone on the same computer. (This is different from echo cancellation, which completely removes the feedback.)
Generally, echo suppression is advisable when the sound being captured is played through speakers—instead of a headset—on the same computer. If your SWF file allows users to specify the sound output device, you may want to call Microphone.setUseEchoSuppression(true) if they indicate they are using speakers and will be using the microphone as well.
Users can also adjust these settings in the Flash Player Microphone Settings panel.
The following example turns on echo suppression.
my_mic.setUseEchoSuppression(true);
Microphone.setGain(), Microphone.useEchoSuppression()
