Abstract
An audio in/out device includes an audible in/out transducer operable to convert an audible input signal to an audio receive (RX) signal and convert an audio transmit (TX) signal to an audible output signal. The audio in/out device further includes an audio receive/transmit (RX/TX) circuit operable to convert a digital TX signal to the audio TX signal for transmission to the audible in/out transducer, receive the audio RX signal from the audible in/out transducer, and convert the audio RX signal into a digital transmit/receive (Tx/Rx) signal. The digital Tx/Rx signal includes a representation of the audio RX signal.
