// x/(x + a) is a common and delightful way to get an easy asymptote and output between
// 0 and 1. Here, the result is above 2/3 for almost everything on screen; drops down
// to 1/3 for things 20 tiles away (which is, roughly, the periphery when standing in
// the center of a CC1 map), and bottoms out at 1/15 for standing in one corner of a
// CC2 map of max size and hearing something on the far opposite corner.

// 0 and 1. This arbitrary factor of 2 seems to work nicely in practice, falling off
// quickly so you don't get drowned in button spam, but still leaving buttons audible
// even at the far reaches of a 100×100 level. (Maybe because gain is exponential?)
