Soundmanager 2波形数据

Question

我想在画布上为音频创建和音频可视化，并决定使用SoundManager2。问题是应该返回波形数据抛出空数组的函数。知道该怎么办？ （我听到声音正在播放，所以加载正确:)）

    <script>
    (function() {

     soundManager.url = 'swf/';
     soundManager.flashVersion = 9;

      soundManager.onready(function() {

       var i = 0;

var song = soundManager.createSound({
  id: 'song',
  url: 'https://www.mash-up.pl/sites/default/files/mp3/HF028A.mp3'
});

console.log(soundManager.features.waveformData); // true

function draw() {

  // emit waveform data every once in a while as to not break console
  if (!(i % 200)) {
    // wth these are empty
    console.log(song.waveformData.left);
    console.log(song.waveformData.right);
  }

  i++;
  window.webkitRequestAnimationFrame(draw);

}

draw();

song.play();

     });

   })();

Answer 1

确定已经发现soundobject将useWaveformData设置为false（在控制台中调试后找到它）。

问题可以关闭：）
