Question

我想将一个bytearray解码为audiobuffer并使用JS在浏览器中播放我的wav文件。这里我使用的代码，但点击播放按钮我得到一个例外，即“无法解码音频数据”。

{
    if (!window.AudioContext){
        if (!window.webkitAudioContext){
            alert("Your browser does not support any AudioContext and cannot play back this audio.");
            return;
        }
    }

   var context = new AudioContext();
   var arr = me.queueStore.getAt(0).data.ByteAudio;
   var arrayBuffer = new ArrayBuffer(arr.length);
   var bufferView = new Uint8Array(arrayBuffer);
    for (i = 0; i < arr.length; i++) {
          bufferView[i] = arr[i];
    }    
    context.decodeAudioData(bufferView, function (buffer) {
    var source = context.createBufferSource(); // creates a sound source
    source.buffer = buffer;                    // tell the source which sound to play
    source.connect(context.destination);                            
    source.start(0);
  });
}

得到了答案，这里是解决方案：使用64位字符串播放媒体文件而不是转换为音频缓冲区： me.fileString = "data:audio/wav;base64," + data.tonebyteArray; var audio = new Audio(fileString); audio.play();
