Usage

import { createStorageUriResolver } from "@suaveplan/storage-uri";
import { PluginChain, DefaultBusRegistry } from "@suaveplan/audio-fx-plugin-base/chain";
import { EQPlugin, EQ_PRESETS } from "@suaveplan/audio-fx-plugin-eq";

const eq = new EQPlugin();
const chain = new PluginChain({
 buses: new DefaultBusRegistry(),
 plugins: [eq],
});

eq.applyPreset(EQ_PRESETS.vocalAir);

Composition

This package depends on @suaveplan/audio-fx-plugin-base for the AudioFxPlugin contract and the chain primitives. It declares no transitive @suaveplan/audio-fx-plugin-* deps — the dependency arrow points only at the foundation.

Status

Replaces the ./eq subpath of the bundled @suaveplan/audio-plugins-fx.
