Audio streaming to iPhone

I now have the audio streaming from ghpsdr to the iPhone. I am sending it at 8K samples per second and sounds OK. Did a very simple implementation of taking 1 in 6 of the 48K samples being fed back to Mercury. Also just sending one channel.

Now it needs the ability to change band, filters and mode for a fully functional internet radio.

I should get a development board for the iPhone next week which will let me dock the iPhone and get access to line-in and line-out. I intend to look at taking the I/Q data from a softrock receiver and processing it directly on the iPhone. Should make a great little portable receiver.
