WAWorkletNode class

An AudioWorkletNode — connects a custom processor to the audio graph. Mirrors Web Audio API AudioWorkletNode.

final dx7 = WAWorkletNode(
  ctx,
  'dx7-processor',
  parameterDefaults: {'gain': 0.8},
);
dx7.connect(ctx.destination);
dx7.port.postMessage({'type': 'noteOn', 'note': 60});
