Applies to weapon_pistol, weapon_heavy_pistol, weapon_smg, weapon_carbine,
weapon_assault, weapon_lmg, weapon_marksman, weapon_sniper, weapon_shotgun
and the rifle_fire fallback. Single near-microphone takes were excerpted,
converted to mono/48 kHz, filtered for rumble, gain-matched and faded.
Automatic-weapon tails were shortened; weapon_lmg uses a separate AK-47
take at 0.96 resampling ratio. It is not represented as an actual LMG recording.
Source firearm names describe recordings only; they do not rename game weapons
or imply endorsement by the recordists or firearm manufacturers.
