Hi Mostafa,
If I understand correctly, you want to digitize an audio signal, send it wireless for a short distance and then decode it back to audio? Question: why go through all this brain damage and expense when you can send audio in analog format very easily and cheaply via an FM transmitter? FM units are available on the cheap from many "hobbiest suppliers" or you can roll your own, also wireless mic's are available, here's a source:

In all sincerity, I have to echo Joe S's question. Another straightforward and economical solution would be:

The audio will be what we old farts call "communication quality"--about as good as you hear on a land-line telephone.

Perhaps I don't completely understand your project?

There is just no way that you can sample fast enough for good quality audio.

You might look at Roman Black's PicSound page at http://www.romanblack.com/picsound.htm.

hi

thanks all.

ultimately i decided to use the MC3361 (narrowband FM IF) as receiver and MC2833 (FM transmitter) as transmitter.

is it a good idea?

best regards, Mostafa
