Abstract: Systems and techniques for processing signals representative of sound for conveyance to the auditory system of a subject based on the identity of an input device. In one implementation, a method includes identifying an input element to an audiological system that conveys sound information directly to a subject's auditory system, automatically setting parameters for processing the signal based on the identity of the input element, and processing the signal in accordance with the processing parameters. The input element is configured to generate a signal representative of sound.
