This report describes an implementation of a cochlear model proposed by Roy Patterson [Patterson1992]. Like a previous report [Slaney1988], this document is an electronic notebook written using a software package called Mathematica™ [Wolfram 1988]. This report describes the filter bank and its implementation. The filter bank is designed as a set of parallel bandpass filters, each tuned to a different frequency. This report extends previous work by deriving an even more efficient implementation… 
AN ANALYSIS / SYNTHESIS AUDITORY FILTERBANK BASED ON AN IIR GAMMACHIRP FILTER
A number of auditory models have been developed for telecommunications systems that incorporate human auditory characteristics. Recent attempts do a good job, based on physiological comparisons,

  • 2013
TLDR
A multi-rate implementation of auditory filter bank is presented, which can greatly reduce the computation requirement through using low sampling rate for the filters with low centre frequency, and using high sampling rate with high centre frequency.
An analysis/synthesis auditory filterbank based on an IIR implementation of the gammachirp
TLDR
A new auditory filter bank that enables signal resynthesis from dynamic representations produced by a level-dependent auditory filterbank based on a new IIR implementation of the gammachirp that is expected to be useful in various applications where human auditory filtering has to be modeled.
Improvement of an IIR asymmetric compensation gammachirp filter
An IIR implementation of the gammachirp filter has been proposed to simulate basilar membrane motion efficiently (Irino and Unoki, 1999). A reasonable filter response was provided by a combination of

A time-varying, analysis/synthesis auditory filterbank has been developed using a new implementation of the "gammachirp", which has been shown to be an excellent function for the asymmetric,
Practical Gammatone-Like Filters for Auditory Processing
TLDR
Results are provided that shed light on the characteristics and attributes of the DAPGF and OZGF responses that provide a robust foundation for modeling cochlea transfer functions and can also serve as "design curves" for fitting these responses to frequency-domain physiological data.
Auditory filter bank inversion
TLDR
A new auditory filter bank inversion method using a least squares optimization technique is proposed that is computationally efficient and its low delay makes it suitable for frame-by-frame processing.
Auditory filter bank design using masking curves
TLDR
An inexpensive method of generating psychoacoustic tuning curves from the well-known masking curves in critical band rate is presented and a method for designing critical band auditory filters from the tuning curves is presented.
Analog complex gammatone filter for cochlear implant channels
TLDR
The design of an analog complex gammatone filter is introduced in order to extract both envelope and phase information of the incoming speech signals as well as to emulate the basilar membrane spectral selectivity.
DSP-Based Implementation and Optimization of Auditory Filter-Bank
TLDR
A brief introduction to the auditory filter-bank is given, and its DSP-based implementation and optimization in details are discussed in details.

TLDR
It is shown that the newer extended data on human cadaver ears and from living animal preparations are quite well fit by the same basic function, which increases the function's value in plotting auditory data and in modeling concerned with speech and other bioacoustic signals.
