Hi, @ChaoshengZhang, can do describe what you want to do in more detail?

[ChaoshengZhang]

I want to know how to draw the whole audio waveform directly. I hope you can help me answer the questions. Thank you. Is it the HTML 5 API or something else, I hope you can provide some ideas. Thank you. 我想知道，通过什么方法直接绘制整个音频的波形图的，希望你们帮我解答疑惑，谢谢你。是html5的api还是什么其他的，希望你可以提供一下思路。谢谢你。

I recommend that you look at our waveform-data.js module. The ReadMe has some example code that shows how to draw a waveform using the HTML Canvas API.
