AudioWorkletProcessor type definition is missing

TypeScript Version: 3.2.0-dev.201xxxxx

Search Terms: AudioWorkletProcessor

You guys have type definitions for AudioWorkletNode and such but missed the definition for AudioWorkletProcessor as per: https://webaudio.github.io/web-audio-api/#audioworkletprocessor

This is what I have for now:

interface AudioWorkletProcessor {
    readonly port: MessagePort;
    process(inputs: Float32Array[][], outputs: Float32Array[][], parameters: Map<string, Float32Array>): void;
}

declare var AudioWorkletProcessor: {
    prototype: AudioWorkletProcessor;
    new(options?: AudioWorkletNodeOptions): AudioWorkletProcessor;
}

Cheers

I think the typescript DOM lib generator publishes this to package @types/audioworklet but that needs to be manually added to your package.json

The definition of registerProcessor was missing as well.

I’m using the following definitions:

interface AudioWorkletProcessor {
  readonly port: MessagePort;
  process(
    inputs: Float32Array[][],
    outputs: Float32Array[][],
    parameters: Record<string, Float32Array>
  ): boolean;
}

declare var AudioWorkletProcessor: {
  prototype: AudioWorkletProcessor;
  new (options?: AudioWorkletNodeOptions): AudioWorkletProcessor;
};

declare function registerProcessor(
  name: string,
  processorCtor: (new (
    options?: AudioWorkletNodeOptions
  ) => AudioWorkletProcessor) & {
    parameterDescriptors?: AudioParamDescriptor[];
  }
);

EDIT: added the parameter descriptors to the registerProcessor() declaration.
