Client-Side Communication ActionScript 51

Description

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 movie 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.

Example

The following example turns on echo suppression.

_root.myMic.setUseEchoSuppression(true);
