setRate (Microphone.setRate method)

rate:Number - The rate at which the microphone should capture sound, in kHz. Acceptable values are 5, 8, 11, 22, and 44. The default value is 8 kHz if your sound capture device supports this value. Otherwise, the default value is the next available capture level above 8 kHz that your sound capture device supports, usually 11 kHz.

Example

The following example sets the microphone rate to the user's preference (which you have assigned to the userRate variable) if it is one of the following values: 5, 8, 11, 22, or 44. If it is not, the value is rounded to the nearest acceptable value that the sound capture device supports.

active_mic.setRate(userRate);

The following example lets you use a ComboBox instance, called rate_cb, to change the rate at which your microphone captures sound. The current rate displays in a Label instance called rate_lbl.

this.createEmptyMovieClip("sound_mc", this.getNextHighestDepth());
var active_mic:Microphone = Microphone.get();
sound_mc.attachAudio(active_mic);
var rate_array:Array = new Array(5, 8, 11, 22, 44);
rate_cb.dataProvider = rate_array;
rate_cb.labelFunction = function(item:Object) {
    return (item+" kHz");
};
for (var i = 0; i<rate_array.length; i++) {
    if (rate_cb.getItemAt(i) == active_mic.rate) {
    rate_cb.selectedIndex = i;
    break;
    }
}
function changeRate() {
    active_mic.setRate(rate_cb.selectedItem);
    rate_lbl.text = "Current rate: "+active_mic.rate+" kHz";
}
rate_cb.addEventListener("change", changeRate);
rate_lbl.text = "Current rate: "+active_mic.rate+" kHz";

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.
