Replace the example below with this:

function shuffle(array){
  for(let i=array.length-1;i>=0;i--){
    const j=Math.floor(Math.random()*(i+1));
    [array[i],array[j]]=[array[j],array[i]];
  }
}
let mix=(a,b,x)=>a+x*(b-a),delays=[],last=[],route=[],mult=[],del=[],sampleRate=8000;
for(let i=0;i<30;i++){
  delays.push(new DelayLine({
    maxDelayInSamples:sampleRate,
    numChannels:1,
    interpolationType:"linear"
  }));
  del.push(mix(10,200,Math.random()**.5));
  delays[i].setDelay(del[i]);
  last.push(0);route.push(i);mult.push(mix(.85,.94,Math.random()));
}
shuffle(route);
let processDelays=(x,time)=>{
  let o=x;
  for(let i=0;i<delays.length;i++){
    delays[i].pushSample(0,o-last[route[i]]*mult[i])
    delays[i].setDelay(del[i]+sin(i**3.8+time*1.4)*60);
    last[route[i]]=delays[i].popSample(0);
    o+=last[route[i]]*.12
  }
  return o;
};
return t=>{
  let o=(sin(PI*2*200*t)*(1-t%[.23,.3,.23,.55][(t*.7|0)%4])**90)+(Math.random()*(1-t%[.2,.5,.63,.7][(t*1.3|0)%4])**100)*.2;
  o=processDelays(o,t);
  return Math.tanh(o);
};
