Handgun Shot

How it's made

Source

a handgun discharge outdoors. Burning propellant makes a muzzle blast, a broadband pressure step of 3–8 ms that collapses into a low "pop"; a supersonic bullet adds a sharp N-wave crack above 2 kHz.

Body

the barrel and expanding gas give a short low thump (a sine falling ≈ 190 → 70 Hz in 60 ms) and a noise blast low-passed from ≈ 4 kHz down to ≈ 700 Hz over 50 ms; a weak 200–500 Hz chamber tone fills the mids.

Envelope

crack 10–25 ms, blast 40–90 ms, thump 80–150 ms, then an exponential low-passed tail of ≈ 0.25 s as the gas cloud and ground reflection die away; there is no sustain.

Slap echo

one reflection off a distant wall or tree line, 90–260 ms later, low-passed (air absorbs the highs), −12 to −6 dB, followed by a fainter second bounce at 1.7× the delay.

Variation

`rng` jitters crack brightness, thump pitch and echo timing a few percent per seed; `caliber` scales body size and weight, `snap` the crack level and bandwidth, `distance` the echo delay and its level.
