The gain and asymmetry of this parallel cGC filter are shown to be comparable to those of the roex(p, w, t) filter, but the fits to masking data are still somewhat unstable.

The compressive gammachirp auditory filter (cGC) consists of a passive gammachirp filter (pGC) and a high-pass asymmetric function (HP-AF).

A gammatone filter is a linear filter described by an impulse response that is the product of a gamma distribution and sinusoidal tone. It is a widely used model of auditory filters in the auditory system. A gammatone response was originally proposed in 1972 as a description of revcor functions measured in the … See more Variations and improvements of the gammatone model of auditory filtering include the complex gammatone filter, the gammachirp filter, the all-pole and one-zero gammatone filters, the two-sided gammatone filter, … See more • Slaney's implementation in Mathematica • Cooke's implementation in C Archived 2012-04-14 at the Wayback Machine • A real-time implementation in C++ (for PureData) See more WebJun 4, 1998 · The gammachirp has a well-defined impulse response, unlike the conventional roex auditory filter, and so it is an excellent candidate for an asymmetric, …
