Here's a simple tut from Adobe on tying Audio to Size:

http://studio.adobe.com/us/tips/tip.jsp?p=1&xml=aft6audio&id=396#

The tut is nice because it tells you how to tweak the expression to get the sizes you want. The same principal works for position, see expressions below.

Audio moves both x and y

ak = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider")
value + [ak, ak]


audio moves y only

ak = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider")
value + [0, ak]

Audio moves x only

ak = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider")

value + [ak, 0]

If you want the layer to get slightly larger with the beat, use the "value +" as above, expression for Scale follows:


ak = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider")
value +[ak, ak]


That first line that defines "ak" above is just what you get when you pickwhip to the Both Sliders in the Audio Keyframe layer as in the tut.
