[Shotimes] (OT) wireless audio from computer throughout house

[van Oss]

(OT)

I would like to be able to spread music from my desktop computer throughout 
our 1-acre property.  I picture attaching a wireless broadcast device to the 
computer and placing wireless receiver/amp/speaker units around the house 
and grounds.

The Google searches I've done have yielded a lot of irrelevant stuff.  Is 
anyone on the list familiar with technology that would do what I'm seeking? 
It's gotta exist.
