Usage
active_mic.activityLevel:Number
Description
Read-only property; a numeric value that specifies the amount of sound the microphone is
detecting. Values range from 0 (no sound is being detected) to 100 (very loud sound is being
detected). The value of this property can help you determine a good value to pass to the
Microphone.setSilenceLevel() method.
If the microphone is available but is not yet being used because
Microphone.get() has not been
called, this property is set to -1.
Example
The following example displays the activity level of the current microphone in a ProgressBar
instance called
activityLevel_pb.
var activityLevel_pb:mx.controls.ProgressBar;
activityLevel_pb.mode = "manual";
