Actionscript 3 :: Enable Features According To Flash Player Version

I'd like to know if it is possible to enable/disable some piece of code according to Flash Player version in ActionScript 3.

Let's say; I have a custom class customClass that uses flash.media.Microphone. The Microphone class has a property isSupported which is available for Flash Player version 10.1 and above (as stated in the documentation). I implement this property in my customClass... so:

I need something like this (by checking with the built-in Capabilities.version):

if (version >= 10.1) {
trace(_mic.isSupported); //this will throw an error if the debug version is not 10.1 or later
} else {
doSmthElse();
}
