At the moment I have the following code
AudioContext = window.AudioContext || window.webkitAudioContext;
context = new AudioContext({latencyHint: 'interactive'});
processor = context.createScriptProcessor(bufferSize, 1, 1);
processor.connect(context.destination);
context.resume();
I need to migrate the AudioWorkletNode. The main function here is the "createScriptProcessor". I am struggling to find the equivalent of this. Please help!
Instead of createScriptProcessor, you need to something more complicated. You can find a couple of examples in the spec itself. There are other demos with the basic Hello Audio Worklet being a good place to start.
It becomes two lines:
await context.audioWorklet.addModule( url_worklet );
processor = new AudioWorkletNode( context , 'worklet-processor', {} );
And the content of the "processor.onaudioprocess" function goes to an external object, but you can still write it in the same script as follows:
let url_worklet = URL.createObjectURL( new Blob([ '(', function(){
class WorkletProcessor extends AudioWorkletProcessor {
constructor (options) { super(); }
process(inputs, outputs) {
console.log( inputs[0][0] ); // the onaudioprocess code here
return true;
}
}
registerProcessor('worklet-processor', WorkletProcessor);
}.toString(), ')()' ], { type: 'application/javascript' } ) );
The names "WorkletProcessor" and "'worklet-processor'" can be edited.
Enjoy
