如何格式化原始音频文件以导入大胆？

Question

我试图在JavaScript中生成PCM（脉冲代码调制）代码，以将其导入Audacity作为原始数据。运行代码后，我将显示的文本复制并粘贴到将其保存为.txt文件文件自动在我的代码中，我会感谢它）。我尝试使用标准的440 Hz正弦波测试，但是当我用，我刚刚听到铃声（大于440 Hz）和噪音。

let list = [] // list of plot points
let t = 0 // theta
let sampleRate = 48000 // sampling rate in Hz
let bitDepth = 24 // bit depth in bits
let length = 1 // length of sound in seconds
let binary = "" // plot points converted to binary in this string
let binaryList = [] // list of plot points in binary
let byteList = [] // list of binary values separated into bytes


for (i = 0; i < sampleRate * length; i++) {
  t = t + 2 * Math.PI / sampleRate
  list.push(Math.sin(440 * t))
}
// generates plot points (440 Hz sine wave in this case)



for (i = 0; i < list.length; i++) {
  list.splice(i, 1, Math.round(2 ** (bitDepth - 1) * list[i]) + 2 ** (bitDepth - 1))
}
let j = bitDepth
for (i = 0; i < list.length; i++) {
  j = bitDepth
  binary = ""
  while (list[i] > 0) {
    while (2 ** j > list[i]) {
      j = j - 1
      binary = "0" + binary
    }
    list.splice(i, 1, list[i] - 2 ** j)
    binary = "1" + binary.substr(1, binary.length - 1)
  }
  binaryList.push(binary)
}
// converts plot points to binary



for (i = 0; i < binaryList.length; i++) {
  while (binaryList[i].length < bitDepth) {
    binaryList.splice(i, 1, "0" + binaryList[i])
  }
}
// puts 0's in front of each binary value to define all place values (e.g. 101 in 8 bit would become 00000101) 



for (i = 0; i < binaryList.length; i++) {
  for (j = 0; j < bitDepth / 8; j++) {
    byteList.push(binaryList[i].substr(8 * j, 8))
  }
}
// separates binary values into bytes



let text1 = String(byteList)
let text2 = ""
for (i = 0; i < text1.length; i++) {
  if (text1.substr(i, 1) == ",") {
    text2 = text2 + " "
  } else {
    text2 = text2 + text1.substr(i, 1)
  }
}
// replaces commas list with spaces in list

document.getElementById("demo").innerHTML = text2

<p id="demo"></p>

我的代码中有错误吗？数据格式不正确？错误的文件格式？大胆的设置错误？
