public setRate(rate:Number) : Void
Sets the rate, in kHz, at which the microphone should capture sound.
Availability: ActionScript 1.0; Flash Player 6
Parameters
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");
};
