Actually, looking at a post from this developer, it looks like the .bytesAvailable > x is the main target to determine the amount of sound. https://forums.adobe.com/thread/1096313
//if audio bytes is greate than 4 read the recorded byte array data and write it into the sound
for (var i=0; i<8192; i++)
{
if (soundBytes.bytesAvailable > 4)
{
var sample:Number = soundBytes.readFloat();
e.data.writeFloat(sample);
e.data.writeFloat(sample);
}
}

 I don't have a mic on me, so I can't test it.  However this might be in the area you are looking for:
microphone.addEventListener(SampleDataEvent.SAMPLE_DATA, onSampleData);

private function onSampleData(event:SampleDataEvent):void { while(event.data.bytesAvailable > 0)
 _buffer.writeFloat(event.data.readFloat()); }
