Parametric EQ
Parametric EQ — a cascade of up to 12 matched-biquad bands (low/high SHELF, sweepable PEAK, notch, LP/HP), each dragged directly on the response curve. The KERNEL designs the coefficients with the Vicanek matched method at f64 and streams them to a melody-owned worklet (eq-rt), so a band lands on its true frequency with a fraction-of-a-dB accuracy near Nyquist that a native BiquadFilterNode's RBJ f32 cannot reach — and the drawn curve IS the running filter (H11). Flat (all bands 0 dB) = transparent. Bands live in the node's eq_bands store (edited full-replace via set_eq_bands), not as automatable AudioParams. Insertable.
