使用Javascript Code:

<script>
  function play(music,time){
    //參考http://www.csie.ntnu.edu.tw/~u91029/Audio.html
    var sampleRate   = 10000;
    var sampleNumber = music[0].length*10000*time;
    var ctx    = new AudioContext();
    var buffer = ctx.createBuffer(2, sampleNumber, sampleRate);


    //製作聲音資料
    var data0   = buffer.getChannelData(0); //第1聲道
    var data1   = buffer.getChannelData(1); //第2聲道
    for (var i = 0; i < sampleNumber; ++i){
      var index=Math.floor(i/(sampleRate*time));
      data0[i] = Math.sin((Math.PI * 2) * i * music[0][index] / sampleRate);
      data1[i] = Math.sin((Math.PI * 2) * i * music[1][index] / sampleRate);
    }

    // 製作節點、串連節點、播放聲音
    var node    = ctx.createBufferSource();
    node.buffer = buffer;
    node.connect(ctx.destination);
    node.start(0);
  }
