1. A method of operating one or more processors, the method comprising: post-processing raw banded gains to generate banded post-processed gains to apply to one or more audio signals, the raw banded gains determined by input processing the one or more input audio signals to generate the raw banded gains at a plurality of frequency bands, some of the bands comprising more than one frequency bin, the raw banded gains being in order to carry out one or more of reducing noise, reducing out-of-location signals, reducing echoes, perceptual domain-based leveling, perceptual domain-based dynamic range control, and perceptual domain-based dynamic equalization, wherein the generating of a particular post-processed gain for a particular frequency band includes at least median filtering using raw gain values for frequency bands adjacent to the particular frequency band, thereby yielding median filtered gains, wherein the post-processing is according to one or more properties, including an end condition and a width for the median filtering, and wherein at least one of the end condition of the median filtering and the width of the median filtering depends on signal classification of the one or more input audio signals.
