WebThe Gammatone Auditory Filterbank. The gammatone auditory filter is defined in the time domain and it is essentially a section of a cosine wave, cos ( 2πfct + Ø ), whose rate of onset is specified by a power function, t(n-1), and whose rate of offset is determined by a decaying exponential function, e-2πbt. Thus the gammatone filter, gt (t ... WebGammatone-filters is a Python library typically used in Utilities, Math, Latex applications. Gammatone-filters has no bugs, it has no vulnerabilities, it has build file available and it has low support.
WebA 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 cochlear nucleus of cats. [1] The ...
