Can JS to take data directed to sound ports and stream it elsewhere?

Hello all

here is a question that will reveal my complete beginner-ness as far
as JavaScript is concerned...but is it possible to use JavaScript to
take data that another application is sending e.g. to the speakers and
stream that data somewhere else such as to a TCP/IP port?

The reason for my question is that I am interested of seeing if it is
possible to create a JavaScript Internet Radio Station application. So
this would basically be an application that can run inside a web
browser.

Thanks in advance for any information about this
