First create hidden audio elements and build a custom control UI, and then connect functions such as playback, pause, progress adjustment and volume control to the audio API through JavaScript to achieve a fully personalized audio player.

Use ARIA attributes to supplement semantics, such as role="button", tabindex="0" and aria-label; 2. Support keyboard focus and Enter key trigger events; 3. Provide visual feedback, such as focus outline, disabled status and loading prompts. For example: ?Make sure that all users can operate the controls smoothly.

To ensure compatibility, it is recommended to provide MP3, OGG, WAV and other formats at the same time. The browser will automatically select the supported format to play 3. Common properties include autoplay to realize automatic playback loops to make audio loop play muted setting default muted. These settings need to be controlled in combination with user interaction or JavaScript to avoid being intercepted by the browser 4. Among common audio formats, MP3 has strong universality and OGG open source support is good WAV lossless suitable for short audio. Reasonable use of these functions can enhance web page interaction and pay attention to format compatibility and playback strategy issues.

Use the loop attribute to realize HTML5 audio loop playback. If you need to accurately control the loop interval, you can listen to the timeupdate event through JavaScript and set the start and end time to achieve repeated playback of specific clips.
