为什么它不读取 JavaScript 中的音频源？

如何解决为什么它不读取 JavaScript 中的音频源？

我提出一个问题。谁知道，为什么我不阅读Audio src的代码有什么问题？我敢打赌，重点是源是没有给定持续时间的收音机的流网址，但我不知道自己，所以我可能是错的

var useMic = false;

var ctx = canvas.getContext("2d");
ctx.fillRect(20,20,40,16);

function preload(){

}

function setup(){
  createCanvas(1200,600);
  colorMode(HSB);
  filter(BLUR,100);
  audio.play();  
  fft = new p5.FFT(0.9,64);
  linespace = (width/2) / 64;
}

function draw(){
  background(0);
  
  let spectrum = fft.analyze();
  for (let i = 0; i < spectrum.length; i++) {
    fill(i*3,255,255); //fill(i,255);
    let amp = spectrum[i];
    let y = map(amp,256,height,350);
    rect((width/2) + (i * linespace),y,linespace,height - y);
    rect((width/2) - (i * linespace),height - y);
  }
}

function touchStarted(){
  getAudioContext().resume();
