Many people doing work with auditory perception use a simple linear model based on critical bands. Based on the work of Roy Patterson and John Holdsworth, a good fit for this data is provided by a Gammatone function. This notebook describes a new efficient implementation and includes C, Fortran, and Matlab implementations. This notebook depends on the filter design functions contained in the "Review of Filter Design" notebook from "A Review of Filter Design" (item 81).
