Or is it widely accepted that what you generate mathematically will be reflected in the pressure at the hearers eardrum?
It's just that, looking at your waveform, I'm thinking, what could upset the perception of volume in this case? Or the actual volume of the components? The first thing that occurs to me is an assymetric excursion of the driving element. Such as might occur if the signal had a DC offset?
With regard to the miking of the drumkit, I couldn't agree more.
