Detailed Description

Second-order state variable filter (SVF) smoother (TPT implementation).

Internal state is double precision: smoothing time constants put the cutoff a few Hz above DC, where g = tan(pi*fc/fs) is ~1e-4 and float recursion stalls several 1e-5 short of the target (the settle check would then never fire). The public API stays float.
