AudioGraphBuilder.eq() method
A multi-band parametric EQ: bands biquads applied in series as one node. Each band’s filter kind is fixed at build; its frequency/Q/gain are runtime-tunable via AudioGraphNode.setParams() eqBands (entry i tunes band i). The number of bands is fixed at build.
Signature:
eq(input: AudioNode, opts: {
bands: {
kind: "lowPass" | "highPass" | "bandPass" | "notch" | "lowShelf" | "highShelf" | "peaking";
cutoffHz: number;
q: number;
gainDb?: number;
}[];
name?: string;
}): AudioNode;
