带有fetch的WebAudio流：DOMException：无法解码音频数据

Question

我正在尝试使用Chrome 51播放来自fetch API的无限流。（作为Microsoft PCM的网络摄像头音频流，16位，单声道11025 Hz）

代码与mp3文件几乎没问题，除了一些故障，但由于某种原因它完全无法使用wav文件我得到“DOMException：无法解码音频数据”

该代码改编自这个答案Choppy/inaudible playback with chunked audio through Web Audio API

有没有想过它是否可以使它与WAV流一起使用？

function play(url) {
  var context = new (window.AudioContext || window.webkitAudioContext)();
  var audiostack = [];
  var nextTime = 0;

  fetch(url).then(function(response) {
    var reader = response.body.getReader();
    function read() {
      return reader.read().then(({ value, done })=> {
        context.decodeAudioData(value.buffer, function(buffer) {
          audioStack.push(buffer);
          if (audioStack.length) {
              scheduleBuffers();
          }
        }, function(err) {
          console.log("err(decodeAudioData): "+err);
        });
        if (done) {
          console.log('done');
          return;
        }
        read()
      });
    }
    read();
  })

  function scheduleBuffers() {
      while ( audioStack.length) {
          var buffer    = audioStack.shift();
          var source    = context.createBufferSource();
          source.buffer = buffer;
          source.connect(context.destination);
          if (nextTime == 0)
              nextTime = context.currentTime + 0.01;  /// add 50ms latency to work well across systems - tune this if you like
          source.start(nextTime);
          nextTime += source.buffer.duration; // Make the next buffer wait the length of the last buffer before being played
      };
  }
}

只需使用play（'/ path / to / mp3'）来测试代码。（服务器需要启用CORS，或者与运行脚本位于同一个域中）
