WebRTC Audio one to many unlimited listeners

I hope I can find an answer to my idea here.

I would like to broadcast audio via webrtc. meaning, there will be one admin streaming audio only and everyone else will be listening. no one will be communicating with each other. think about it as a radio.

simply share a page where everyone can press play and listen. the number of listeners is unlimited. 100 to start with would be good but the latency should not be more than 2 to 3-sec max.

If anyone can help with the code and/or how to do it, I appreciate that. I am not a developer but I like to learn. thank you all
