Abstract:
Embodiments of the present invention provide a system, apparatus and method for an audible indicator of a quality of a received digital radio transmission. After receiving a digital radio transmission in a digital radio receiver, the quality of the received digital radio transmission is detected. Then an audible communication from the received digital radio transmission is decoded. Then an audible indicator is superimposed onto the audible communication, to form a composite audible signal. Finally, an amplitude of the audible indicator is dynamically adjusted relative to an amplitude of the audible communication, responsive to a quality of the received digital radio transmission.
