4 Intro

Initially my motivation was to hack the 480L large hall algorithm. Not by reverse engineering - that would be hard to do - but with my ears. Not by looking at the IR. Most of the feeling of "envelopment" seemes to come from time variance anyway. I worked daily with the 480L at university and after that I needed it for my own productions, so I tried to figure out what might be in the box to make my own tool.
