rate (Microphone.rate property)

The rate at which the microphone is capturing sound, in kHz. 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.

To set this value, use Microphone.setRate().

Availability: ActionScript 1.0; Flash Player 6

Example

The following code 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.
