Detailed Description

FIR Hilbert transformer producing sample-aligned analytic signals.

Used by FrequencyShifter (single-sideband shift) and Compressor (analytic envelope detector). The kernel is sample-rate independent and shared per process (lazily built, thread-safe); each instance owns only its delay line.

Threading: owner-managed. prepare/reset are setup-time; process and processBlock belong to the owning (audio) thread. Not internally thread-safe. processBlock installs a DenormalGuard; per-sample callers are expected to guard their own callback (framework convention) - the FIR itself cannot generate denormals, but denormal INPUTS would make all kTaps multiplies slow without one.

Dependencies: DspMath.h, DenormalGuard.h, SimdOps.h.
