Re: Transmitting audio wirelessly?

Hello!
I'm putting together the plans for my next electronics project, and the
one thing I'm not sure if I can do is transmit audio wirelessly -
ignoring the rest of the project, it becomes something like a wireless
headphone connector - I plug circuit A into my computer (via USB and
via the audio-out) and I plug circuit B into my headphones.

Is there any projects described online that meet this general idea? I
looked around, but I didn't find anything.

I was thinking of using the TWS-434 and RWS-434 parts from rentron for
the transmitter / reciever - 433Mhz. Although, this is mostly since
they're the only such parts I've used - I'd love suggestions on what
would be better suited. Cheaper is always nice, but I don't want to get
something that won't work well.

Are there any good / simple IC's that'd be suited for this? I'm
thinking I'd need an analog to digital converter and a matching digital
to analog converter. Is there a simple method to get some basic error
correction encoding as well? My wild guesstimates of bandwith say I
should have lots to spare for such things.

I'll probably have a picbasic controller in both sides of the project,
if that'd help with anything. I'd also like to be able to transmit some
other information than just the audio (not a whole lot, but still) - if
there's a good way to do that (if not, I'll invent a not-so-good way :D
)

Thanks,

You mean like those wireless headphones I got for the wife a few years
back?

When I was a kid they had this thing called 'radio'...... Later
versions did stereo and then hybrid digital.
