我试着做这样的事情source(图)

【问题描述】：

我想问是否有人可以帮助我使用javascript进行环形调制

这是我的代码。我不确定我是否做得对。在开始按钮上，它只是播放带有增益的振荡器。不与音频文件混合。

我尝试做类似这个 GitHub 源

谢谢

function audioFileLoader(fileDirectory, impulseFileDirectory) {
  var audioContext = new AudioContext();
  var soundObj = [];
  soundObj.fileDirectory = fileDirectory;
  soundObj.impulseFileDirectory = impulseFileDirectory;

  // buffer loader code
  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 source = audioContext.createBufferSource();
    source.buffer = soundObj.soundToPlay;
    var oscillator = audioContext.createOscillator();
    oscillator.type = 'sine';
    oscillator.frequency.value = 500;
    var gainNode = audioContext.createGain();

    gainNode.gain.value = 0.5; 
     
    oscillator.connect(gainNode);
    source.connect(gainNode);  
    gainNode.connect(audioContext.destination);
    oscillator.start(audioContext.currentTime);
  };

   return soundObj;
};
var example = audioFileLoader("audio/AcGtr.wav");
document.getElementById('ringmodulation').addEventListener("click", example.play, 
false);
