Give the laser its own voice, and let a body sound like its size

The laser was playing boom() — the BOMB — so the showiest weapon in the game
sounded like the least showy one. zap() is its own: a highpassed crack, two
detuned saws diving through a resonant lowpass, weight underneath so it lands on
a phone speaker, and a triangle that rings after the plane has gone. The dive is
the whole reading; a rising sweep is a charge-up and this thing never charges.

And the NORMAL hit — ball meeting a body without killing it — was borrowing
pock(), the racket thock. That is a bright, dry, stationary-band click: exactly
right for gut on felt and exactly wrong for felt on a torso, which is why hitting
a zombie sounded like hitting a wall. thud() falls instead of sitting still,
which is where the wetness comes from, with one quiet bright tick just behind the
slap: something gave. The machine keeps its pock — it is furniture and it rings.

Both thud() and splat() now take a size, zombieH/1.8, so 1 is a shambler, 1.5 a
brute and 2.04 a chapter-4 boss. Everything pitches down and lengthens with it.
Measured through a patched AudioParam rather than assumed: the body thump under a
hit runs 150 Hz on a shambler, 100 on a brute, 59 on the boss.

splat() got the same treatment while I was in there — a resonant band collapsing
down the spectrum instead of a plain lowpass, plus a second brighter burst a beat
later. One clean hit is a thud; a thud followed by spatter is a body.
