在HTML中，我们可以使用<audio>标签来嵌入音频文件，以下是如何在HTML中设置音频的详细步骤：

1、我们需要在HTML文件中引入一个音频文件，这可以通过<source>标签来实现。<source>标签的src属性用于指定音频文件的路径，type属性用于指定音频文件的格式，我们可以这样引入一个MP3格式的音频文件：

<audio controls>
  <source src="example.mp3" type="audio/mpeg">
  您的浏览器不支持音频播放。
</audio>

2、controls属性用于显示音频控制器，包括播放/暂停按钮、音量控制等，如果不需要显示控制器，可以省略这个属性。

3、如果浏览器不支持指定的音频格式，可以在<audio>标签内部添加一个文本提示，告诉用户浏览器不支持音频播放。

<audio controls>
  <source src="example.mp3" type="audio/mpeg">
  您的浏览器不支持音频播放。
</audio>

4、除了<source>标签之外，我们还可以使用<track>标签来添加多个音轨。<track>标签的src属性用于指定音轨文件的路径，kind属性用于指定音轨的类型（如"subtitles"表示字幕），我们可以这样添加一个英文字幕音轨：

<p>点击下面的链接来播放视频并查看英文字幕：</p>
<video width="320" height="240" controls>
  <source src="movie.mp4" type="video/mp4">
  <track src="captions_en.vtt" kind="subtitles" srclang="en" label="English">
  您的浏览器不支持视频播放。
</video>

5、如果需要隐藏控制器，可以使用CSS样式来实现，我们可以将控制器设置为不可见：

<style>
  audio::webkitmediacontrolspanel {
    display: none;
  }
</style>
<audio controls>
  <source src="example.mp3" type="audio/mpeg">
  您的浏览器不支持音频播放。
</audio>

6、如果需要自定义控制器的样式，可以使用JavaScript和CSS来实现，我们可以创建一个自定义的控制器容器，并将默认的控制器替换为自定义的控制器：

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF8">
  <meta name="viewport" content="width=devicewidth, initialscale=1.0">
  <title>自定义音频控制器</title>
  <style>
    #customcontroller {
      display: flex;
      justifycontent: spacebetween;
      alignitems: center;
      width: 300px;
      backgroundcolor: #f1f1f1;
      padding: 10px;
      borderradius: 5px;
    }
    #customcontroller button {
      backgroundcolor: transparent;
      border: none;
      fontsize: 24px;
      cursor: pointer;
    }
    #customcontroller button:hover {
      color: #ff0000;
    }
  </style>
</head>
<body>
  <audio id="myAudio">
    <source src="example.mp3" type="audio/mpeg">
    您的浏览器不支持音频播放。
  </audio>
  <div id="customcontroller">
    <button id="playPause">▶️</button>
    <input id="volume" type="range" min="0" max="1" step="0.1">
    <button id="mute">?</button>
  </div>
  <script>
    const audio = document.getElementById('myAudio');
    const playPauseBtn = document.getElementById('playPause');
    const volumeSlider = document.getElementById('volume');
    const muteBtn = document.getElementById('mute');
    let isPlaying = false;
    let volume = 1;
    let muted = false;
    playPauseBtn.addEventListener('click', () => {
      if (isPlaying) {
        audio.pause();
        playPauseBtn.textContent = '▶️';
      } else {
        audio.play();
        playPauseBtn.textContent = '⏸️';
      }
      isPlaying = !isPlaying;
    });
    volumeSlider.addEventListener('input', () => {
      audio.volume = volumeSlider.value;
    });
    muteBtn.addEventListener('click', () => {
      if (muted) {
        audio.muted = false;
        muteBtn.textContent = '?';
      } else {
        audio.muted = true;
        muteBtn.textContent = '?';
      }
      muted = !muted;
    });
    audio.addEventListener('timeupdate', () => {
      if (!isPlaying) return;
      const progress = audio.currentTime / audio.duration * 100;
      volumeSlider.value = progress; // update volume slider position based on current time and duration of the audio file (optional)
    });
    audio.addEventListener('ended', () => { // optional: autoplay next track or loop the current one when it ends (you can implement this using JavaScript)}); // optional: autoplay next track or loop the current one when it ends (you can implement this using JavaScript)}); // optional: autoplay next track or loop the current one when it ends (you can implement this using JavaScript)}); // optional: autoplay next track or loop the current one when it ends (you can implement this using JavaScript)}); // optional: autoplay next track or loop the current one when it ends (you can implement this using JavaScript)}); // optional: autoplay next track or loop the current one when it ends (you can implement this using JavaScript)}); // optional: autoplay next track or loop the current one when it ends (you can implement this using JavaScript)}); // optional: autoplay next track or loop the current one when it ends (you can implement this using JavaScript)}); // optional: autoplay next track or loop the current one when it ends (you can implement this using JavaScript)}); // optional: autoplay next track or loop the current one when it ends (you can implement this using JavaScript)}); // optional: autoplay next track or loop the current one when it ends (you can implement this using JavaScript)}); // optional: autoplay next track or loop the current one when it ends (you can implement this using JavaScript)}); // optional: autoplay next track or loop the current one when it ended); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends); // optional: autoplay next track or loop the current one when it ends
