Abstract
There is provided a method for processing an audio input signal and a corresponding audio filter system. The method includes applying non-linear time-domain processing to the input signal to generate a processed copy of the input signal, transforming the input signal and the processed copy of the input signal to the frequency domain, and performing a comparison in the frequency-domain based on the transformed input signal and the transformed processed copy of the input signal. The method also includes determining at least one control parameter based on the comparison, performing frequency-domain processing of the transformed input signal based on the control parameter, and generating an output signal by transforming the frequency-domain processed signal to the time domain.
