Web Audio API如何命名声音

Question

所以目前有两个声音加载到缓冲区中，然后连接到两个声源。如何将BufferLoader中的两个声音命名为“kick”和“hihat”，然后使用kick.start（0）播放它们。我知道这一定很容易，但我无法通过搜索找到任何东西。

window.onload = init; 
var context = new AudioContext(); 
var bufferLoader; 

function init() { 

    bufferLoader = new BufferLoader(
    context, 
    [ 
     'kick.wav', 
     'hihat.wav', 
    ], 
    finishedLoading 
    ); 

    bufferLoader.load(); 
} 

function finishedLoading(bufferList) { 

    var source1 = context.createBufferSource(); 
    var source2 = context.createBufferSource(); 
    source1.buffer = bufferList[0]; 
    source2.buffer = bufferList[1]; 

    source1.connect(context.destination); 
    source2.connect(context.destination); 
    source1.start(0); 
    source2.start(0); 
}

，如果你喜欢，你可以使用我写我自己的抽象：

function audioFileLoader(fileDirectory) { 
    var soundObj = {}; 
    soundObj.fileDirectory = fileDirectory; 

    var getSound = new XMLHttpRequest(); 
    getSound.open("GET", soundObj.fileDirectory, true); 
    getSound.responseType = "arraybuffer"; 
    getSound.onload = function() { 
     audioContext.decodeAudioData(getSound.response, function(buffer) { 
      soundObj.soundToPlay = buffer; 

     }); 
    } 

    getSound.send(); 


    soundObj.play = function() { 
     var playSound = audioContext.createBufferSource(); 
     playSound.buffer = soundObj.soundToPlay; 
     playSound.connect(audioContext.destination) 
     playSound.start(audioContext.currentTime) 
    } 

    return soundObj; 

}; 

var snare = audioFileLoader("snare.mp3"); 


snare.play()
