Default Could this be used for wireless SPDIF?

I was just on the TI site and happened to see an add for this device.....

I have zero programming experience, but just out of curiosity, could it be programmed to send and output a SPDIF signal?

The wireless transceiver in this module (CC2500) is only good for 500kbps. 44.1KHz x 16bit x 2 = 1.411mbps. The other problem is that S/PDIF carries clock information as well, and the wireless transmission is probably buffered and doesn't offer a way to propagate the clock across the link.

So, unfortunately not possible. At the very least it'd be a lot of work - if it were fast enough you could probably get it to work by using large buffers and sending the clock rate in a side channel and regenerating it at the remote end - but it doesn't sound feasible.

Another application for peufeu's ethernet sound interface - slap it behind a wireless bridge and you've got wireless audio...

Thanks for the response.

I know people have had success with "wireless video senders" and SPDIF. However, it would be nice to have an appropriate device that could connect to a PC via USB and send the signal wireless.
