ABSTRACT:
Systems, devices, and methods are provided to inhibit at least one feedback component of an input audio signal by adjusting a feedback-inhibiting filter through a narrowband subaudible signal. The level of the signal may be determined using an audibility model so as to yield its subaudible quality.
