An auditory filter bank attempts to perform signal filtering similar to that of the basilar membrane in the ear. Auditory filter banks are often used as front ends for audio signal processing systems such as speech recognition systems or audio displays. — Click for https://ccrma.stanford.edu/~jos/bbt/Auditory_Filter_Banks.html

Audio Filter Banks It is well known that the frequency resolution of human hearing decreases with frequency [ 71, 276 ]. As a result, any `` auditory filter bank '' must be a nonuniform filter bank in which the channel bandwidths increase with frequency over most of the spectrum.

A filter bankis a system that divides the input signal into a set of analysis signals , each of which corresponds to a different region in the spectrum of . Typically, the regions in the spectrum given by the analysis signals collectively span the entire audible range of human hearing, from approximately 20 Hz to 20 kHz. Also, the regions

In image or signal processing, a Filter Bank is defined as an arrangement of bandpass filters that split the input signal into a set of analysis signals, each one carrying a single frequency sub-band of the original signal. In other words, a class of systems that generates scaling and wavelet function are known as filter banks.
