Microphone class 45

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.
