Note:
 this might seem a little like music rather than science... or much together in the same all the encoding for which is contained in the option setup is all within reasonable the weight of the idea that science can take away or keep however the main point at the empirical level. i much rather take science without question but the idea here is not to take the functions so seriously altogether the tukey gauss functions help but they are hard to maneuver around the weight of quality with the other functions tailing the headphone during the playback decoding.
