Have audio level control the scale of a mc?

I saw somewhere with AS3 it is possible to take an audio wavelength and apply it to parameters of an mc. In After Effects you can also do this. Does anyone know if it is possible in AS2. Or something that would work similar in an AS2 swf? I’ve already tried loading an external AS3 into my AS2 swf in shear hope, but all AS3 scripting is ignored (besides the stop(); command)

Thanks for any help in this regard.
