Returns
Microphone -
■ If index is not specified, this method returns a reference to the default microphone or, if it
is not available, to the first available microphone. If no microphones are available or
installed, the method returns null.
■ If index is specified, this method returns a reference to the requested microphone, or
null if it is not available.
Example
The following example lets the user specify the default microphone, and then captures audio
and plays it back locally. To avoid feedback, you may want to test this code while wearing
headphones.
this.createEmptyMovieClip("sound_mc", this.getNextHighestDepth());
System.showSettings(2);
var active_mic:Microphone = Microphone.get();
sound_mc.attachAudio(active_mic);
The MovieClip.getNextHighestDepth() method used in this example requires Flash Player
7 or later. If your SWF file includes a version 2 component, use the version 2 components'
DepthManager class instead of the MovieClip.getNextHighestDepth() method.

Example
The following example displays the names of the sound capturing devices available on your
computer system in a ComboBox instance called mic_cb. An instance of the Label
component, called mic_lbl, displays the index microphone. You can use the ComboBox to
switch between the devices.
