I'm getting much better at writing compilers, learning where to refactor, and where to un-refactor a shift-reduce grammar to minimise the size of the code generator (no, it isn't better to factor declarator out of init_declarator!)
Having experimented both ways, I suspect I equalize a room better by ear than using the automatic doohickey. The trouble is, I don't have very good absolute pitch, but when I listen to well known recordings, I can spot the bad equalization. Oh well, the initial purpose was only to get rid of painful transients on the dance floor, and if the RTA can do that in a few seconds, credit to it.
