Web Audio API - 记录所有标签声音

Question

有没有办法使用Audio API或其他方法拦截和录制浏览器标签中发生的所有声音。

我们说我在一个标签中同时观看三个YouTube视频，我可以使用Audio API录制吗？

Answer 1

This isn't really directly possible (for security and privacy reasons). As a user, it's possible to set it up - by setting a loopback audio driver as your audio output driver for the YT tabs - but not in a totally automated way.

(This is a duplicate, btw - of Cross application audio analysis with the Web Audio API, et al.)
