Thought about Amplitude had not played with it awhile
Basic steps (simple example)
Set up model and pose to be effected by sound
in pose window right click on pose select plugins wizards then amplitude which gives you choices to set up how sound will effect the pose in volume and frequency then render
If you have further question post a note here I check here daily
