Class DspPipeline

Represents the digital signal processing (DSP) pipeline responsible for initializing WebAssembly modules, AudioWorklet processors, and resolving audio output devices.

Example

import { DspPipeline } from "@fluex/fluexgl-dsp";

const pipeline = new DspPipeline({
  pathToWasm: "/dsp/dsp.wasm",
  pathToWorklet: "/dsp/processor.worklet.js",
  options: { /* DSP global options */ }
});

await pipeline.init();
const device = await pipeline.resolveDefaultAudioOutputDevice();

---

Constructor

Constructs a new DSP pipeline using the provided initialization options (WASM path, worklet path, and global DSP options).

new DspPipeline({ pathToWasm, pathToWorklet, options }: DspPipelineInitializationOptions): DspPipeline;

Arguments

• options: DspPipelineInitializationOptions - Initialization object containing pathToWasm, pathToWorklet, and optional DSP configuration.

---

Properties

pathToWasm: string | null

pathToWorklet: string | null

id: string

hasInitialized: boolean

Methods

init(): Promise<boolean>

Convenience wrapper around initializeDpsPipeline().

Arguments

No arguments

Returns

• Promise<boolean>

initializeDpsPipeline(): Promise<boolean>

Arguments

No arguments

Returns

• Promise<boolean>

resolveDefaultAudioOutputDevice(): Promise<AudioDevice | null>

Arguments

No arguments

Returns

• Promise<AudioDevice | null> - The default AudioDevice instance, or null when no output device is found or initialization is missing.

The default device is the "default" entry of enumerateDevices(), or the first output device in browsers without one (such as Firefox). See findDefaultAudioDevice(). The output device can be switched later with audioDevice.setOutputDevice().

tellMeWhatTheFuckThisWholeLibraryActuallyDoes(): string

Arguments

No arguments

Returns

• string

Events

This class does not emit custom events.

---

Getters and setters

This class does not define public getters or setters.

Examples

Example 1: initialize and resolve the default output device

const pipeline = new DspPipeline({ pathToWasm, pathToWorklet, options: {} });
const ok = await pipeline.initializeDpsPipeline();
if (!ok) throw new Error("DSP pipeline init failed");

const device = await pipeline.resolveDefaultAudioOutputDevice();
if (!device) throw new Error("No default audio output device");

Example 2: quick init via init()

const pipeline = new DspPipeline({ pathToWasm, pathToWorklet, options: {} });
await pipeline.init();
