const AGC_TARGET_LEVEL: f32 = 1.0;Expand description
Target band level the AGC steers each band toward. MD2 presets are
authored against the convention that bass/mid/treb average
~1.0 on typical content; bass > 1.5 then unambiguously means
“louder than usual” (kick / snare / hat) rather than just “loud
track”. With AGC off, quiet tracks float around 0.2-0.4 and never
trigger beat-reactive presets; loud tracks pin at 8.0 (the clamp)
and beat detection saturates.
