我已经成功地在 React 中实例化了一个简单的 AudioWorklet,并希望像 Google 的示例一样启动一个简单的振荡器。为了测试运行它,我正在渲染一个按钮,其 onClick 事件调用以下内容:
src/App.jsx:
userGesture(){
//create a new AudioContext
this.context = new AudioContext();
//Add our Processor module to the AudioWorklet
this.context.audioWorklet.addModule('worklet/processor.js').then(() => {
//Create an oscillator and run it through the processor
let oscillator = new OscillatorNode(this.context);
let bypasser = new MyWorkletNode(this.context, 'my-worklet-processor');
//Connect to the context's destination and start
oscillator.connect(bypasser).connect(this.context.destination);
oscillator.start();
})
.catch((e => console.log(e)))
}
问题是,每次点击时,addModule 方法都会返回以下错误:
DOMException: The user aborted a request.
我在 Ubuntu v16.0.4 上运行 Chrome v66。
src/worklet/worklet-node.js:
export default class MyWorkletNode extends window.AudioWorkletNode {
constructor(context) {
super(context, 'my-worklet-processor');
}
}
src/worklet/processor.js
class MyWorkletProcessor extends AudioWorkletProcessor {
constructor() {
super();
}
process(inputs, outputs) {
let input = inputs[0];
let output = outputs[0];
for (let channel = 0; channel < output.length; ++channel) {
output[channel].set(input[channel]);
}
return true;
}
}
registerProcessor('my-worklet-processor', MyWorkletProcessor);
