From 15d4278b6f9c9cc7d73446ea0d9eb60ff67ffdc6 Mon Sep 17 00:00:00 2001 From: arcattack Date: Thu, 16 Jul 2026 09:12:56 -0500 Subject: [PATCH] Audio: run-speed footfall silence is AUTHORED -- the interior fade curve (task #50) The 'footsteps disappear when running' report traced to the authored interior- footfall volume chain: an AudioScalarScale on LocalVelocity with the INVERTED curve aB=[0,20] -> cB=[1,0] (through a smoother) drives the FootFallInt source volume -- full at standstill, fading with speed, ZERO at >=20 (run). The drop-gate evaluation (CalculateSourceVolumeScale -> ExecuteWatchers) pulls this authored value and overrides the game-side mixer feed, so run-speed footfalls are dropped BY DESIGN: at running speed the pod cockpit is engine roar; the 1995 sound design fades the interior footfall out. Timeline evidence: volset(1,1 from the mixer) -> matchfire Start -> volset(0 from the authored chain during drop evaluation) -> DROP, exactly once per stride at speed >= 20. No code change -- this commit records the finding. User-verified state: chirp gone, per-step static gone (velocity smoothing), footfalls audible at walk, authentically absent at run.
