How it's made

Source
an active sensor emits one short tuned pulse: a sine at 0.8–2.4 kHz gated by a 7 ms soft attack (no click) and an exponential decay of 0.1–0.5 s, with a faint 1 % downward pitch settle.
Body
a thin metallic housing rings next to the tone: inharmonic modes at 2.76x, 5.40x and 8.93x the pitch with decays 0.5x, 0.3x and 0.15x of the main decay; `metal` sets how loud they are, `brightness` tilts them.
Echo
the contact returns delayed copies of the pulse at `spacing` seconds, each quieter by `echoFade` and low-passed progressively (air absorption), so the tail darkens and the pitch stays pure.
Envelope
ping peak at 7 ms, main decay to -60 dB in `decay`; the last echo has faded before the 1.5 s end.
Variation
`rng` detunes the pitch by +-0.5 % and the housing modes by +-0.3 %; presets move pitch, echo count, spacing and metallic content.
