如何使用ScriptProcessorNode执行简单的线性重采样？

var audioContext = new AudioContext();

var scriptNode = audioContext.createScriptProcessor(bufferSize, inputChannels, outputChannels);

scriptNode.onaudioprocess = function(audioProcessingEvent) {
  var inputBuffer = audioProcessingEvent.inputBuffer;
  var outputBuffer = audioProcessingEvent.outputBuffer;

  for (var channel = 0; channel < outputBuffer.numberOfChannels; channel++) {
    var inputData = inputBuffer.getChannelData(channel);
    var outputData = outputBuffer.getChannelData(channel);

    // 执行线性重采样操作
    // 这里可以使用各种算法实现重采样，例如插值法、卷积法等

    for (var sample = 0; sample < inputBuffer.length; sample++) {
      // 处理每个样本的音频数据
      // 这里可以进行采样率转换等操作
      outputData[sample] = inputData[sample];
    }
  }
};

// 连接输入源到ScriptProcessorNode
inputSource.connect(scriptNode);

// 连接ScriptProcessorNode到输出目标
scriptNode.connect(audioContext.destination);
