Microphone actionscript

hello,

i have the actionscript to allow an object to be manipulated by the sound recieved in the microphone:

m = Microphone.get();
attachAudio(m);
m.setUseEchoSuppression(false);
onEnterFrame = function () {
circle._xscale = circle._yscale = m.activityLevel+50;
};

but i need the script to allow the function that when sound is made it triggers a jump to a different frame.

can anyone help me with this?!
