I'm old. I get confused. OK?

comment Need algorithm to take “max” of scores, but with “quality” weighting
@JoshuaShaneLiberman -- I'm not sure I understand the objectives completely, which is part of the problem. But there's an issue with the quality metrics I probably didn't explain very well -- I'll do that.

comment How to add or multiply decimal numbers?
The common way of adding decimal numbers is to use "excess-6" arithmetic, where 6 is added if the digit exceeds 9. There are various clever ways to do this, some more "clever" than they should be, but since the operation tends to be highly optimized the cleverness is usually merited.

comment Sheffer stroke the most important advance in logic?
It's worth pointing out that, in the parallel world of digital logic design, the NAND gate is considered to be the "universal" logical element -- any digital device you want to build can be built fron NAND gates. (And, in fact, this was often done.) I can imagine that if NAND gates had been invented fairly late in the development of digital electronics (rather than being just about the first thing invented) they would have been considered quite magical.

comment Exponential average of logs
@RahulNarain -- I've finally gotten the numbers to where they mostly stay positive, so mainly we're handling noise situations and "transitions". But it would be nice to have a general algorithm so I don't have to worry about discontinuities.

comment peak limiting/audio compression formula needed
Put that in an answer and I'll give you the check. Though I went over to DSP and got a suggestion of new_level = 10 * average * tanh(level/(10 * average)), which works pretty well.
