I'm looking to broadcast CD-quality (or better) so I can play music throughout my home whether it be on the deck, in the kitchen, in the garage, etc that can be picked up by any computer and I'd like it private. Essentially I want to stream music anywhere without having to buy new equipment or run a ton of wires. Is there a (free) app that can do this?
Edit - something I was thinking of is there a way to simulcast without any noticeable lag?
