I want to make sound transfer between two arduino via cable.
how can i transfer sound data (or voice ) two arduino with min 8khz via CABLE.

i can do mic > ADC > PORD > R2R > speaker (no details amp..) with one arduino and simple spi test is ok(hello world :slight_smile: ) but I can not even send my voice or sound data.
