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:

If you do not believe in MAGIC, Consider how currency has value simply by printing it, and is then traded for real assets.

Gold is the money of kings, silver is the money of gentlemen, barter is the money of peasants - but debt is the money of slaves
