Is there an easy and inexpensive way to broadcast audio to the network?

Question

Audio

You want people to be able to hear what's playing on the computer over the network.
Given: computer with windows 10, network connection through a router, static IP.
If anything, the sound source is the browser.

Answer 1

You list all the "dozens of ways"?
The source is not so important, because for the network it will be a computer, and on a computer it is possible even through VLC, even through all sorts of translators, even through remote access programs and presentations
