Microphone.index
Availability
■
Flash Player 6.
■
Flash Media Server (not required).
Usage
public index : Number [read-only]
Description
Property (read-only); a zero-based integer that specifies the index of the microphone, as
reflected in the array returned by
Microphone.names
.
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.
var mic_lbl:mx.controls.Label;
var mic_cb:mx.controls.ComboBox;
this.createEmptyMovieClip("sound_mc", this.getNextHighestDepth());
var active_mic:Microphone = Microphone.get();
sound_mc.attachAudio(active_mic);
mic_lbl.text = "["+active_mic.index+"] "+active_mic.name;
mic_cb.dataProvider = Microphone.names;
mic_cb.selectedIndex = active_mic.index;
var cbListener:Object = new Object();
cbListener.change = function(evt:Object) {
active_mic = Microphone.get(evt.target.selectedIndex);
sound_mc.attachAudio(active_mic);
mic_lbl.text = "["+active_mic.index+"] "+active_mic.name;
};
mic_cb.addEventListener("change", cbListener);
The
MovieClip.getNextHighestDepth()
method used in this example requires Flash Player
7 or later. If your SWF file includes a v2 component (version 2 of the Macromedia
Component Architecture), use the DepthManager class from the component framework
instead of the
MovieClip.getNextHighestDepth()
method.
