Shield Block

How it's made

Source

a weapon (sword edge, axe head or club) hitting a round wooden shield. The strike is a 1–6 ms noise burst; a blunt club is longer and low-passed, a blade edge is shorter and brighter.

Body

the wooden board rings in a few heavily damped inharmonic modes (≈ 1 : 2.57 : 4.2 : 6.5, 40–200 ms) and the air behind the curved shield adds a hollow boom at 80–200 Hz that decays in about 0.25 s.

Rim

the iron rim is a thin metal ring excited by the same blow, a few ms later and much quieter than the wood. It rings in bright inharmonic metal-bar modes (1.2–6 kHz, 0.1–0.35 s) with a slightly detuned pair for beating.

Rattle

the blow shakes loose rim studs and the arm strap. Four to eight tiny metal ticks (2.5–7 kHz, 5–20 ms each) scatter over the first 0.3 s, getting sparser and softer as the shield settles.

Envelope

the wood thump peaks at once and is mostly gone after 0.25 s; the rim clink peaks at about 15 ms and the rattle fades out by 0.4 s, so the whole hit ends near 0.6 s.

Variation

`rng` jitters mode tuning, rim delay, tick times, tick pitch and strength; parameters set shield size, striker hardness, rim loudness and rattle amount; presets move between buckler, heavy and parry.
