All digital devices that produce audio out put IE CD player / dab radio have a digital to analog converter chip, all sounds you hear are analogue if it were in digital all you would hear is just high pitch screeching no matter what sound you are listening to, it would be like hearing Morse Code speeded up thousand fold constantly, phones transmit a digitally signal, there for when you speak into it it has to convert your analogue voice into digital to transmit then convert it back to analogue so you can under stand.
