What I want is something that will be able to stream audio so it could be played back on iPhones and Android phones. I own a sports bar, and we'll usually have the sound from just one game going at once (it is possible to do more than one, but we only do that when there are two big games on at once, like if the Bears and Packers were playing at the same time) If we get a random table that wants to watch say the Dolphins game we can put that on a TV for them, but we can't put the sound on the TV itself because either they won't be able to hear it or it'll disturb everyone near them wanting to listen to a different game.
But I was thinking if I had some devices to capture the sound from a given group of receivers so it could be streamed to customer's phones they could have the sound playing on speakerphone at their table (or even via headphones if they were really serious about listening I guess)
Obviously a device that captured the sound and made it available via wifi all-in-one would be perfect, but I could pretty easily put together a simple web server on my wireless router for the phones to connect to for the streaming audio if necessary. I just don't have any idea how to get the sound off the receivers and onto my network.
If there was one device that could take multiple inputs (let's say six) that would be awesome, though I suspect it would probably be cheaper to buy six small devices rather than one capable of capturing sound from a bunch of receivers at once. Like I said, I don't care if it would be the RCA analog audio or the digital output, the speaker quality of the phone will be the obvious weak link in the chain.
