Claim:
1. A method of post-processing banded gains to generate post-processed gains for applying to an audio signal, the banded gains determined by input processing one or more input audio signals, the method comprising: generating a particular post-processed gain for a particular frequency band of a current frame of the one or more input audio signals, including at least percentile filtering using gain values from one or more previous frames of the one or more input audio signals in a time domain and from gain values for at least one frequency band adjacent to the particular frequency band for the current frame in a frequency domain, wherein the at least one frequency band comprises one or more frequency bins, wherein the gain values from the one or more previous frames use the gain values for the particular frequency band, and wherein the gain values from the one or more previous frames exclude the at least one frequency band adjacent to the particular frequency band for the one or more previous frames.
