Gammatone

‘audio.gammatone’ module within the ketos library.

This module provides utilities to process audio data using a auditory filterbank based on the gammatone function.

Contents:

GammatoneFilterBank class: AuralFeatures class

AuralFeatures(data[, filename, offset, ...])	Aural features computed with the aural-features package (https://pypi.org/project/aural-features/).
GammatoneFilterBank(data, rate, freqs[, ...])	Gammatone filter bank.
apply_weight_func(x, freqs)	Apply C weighting function.
compute_center_freqs(num_chan, sampl_rate, ...)	Compute the center frequencies of the filter bank
compute_filter_coeffs(sampl_rate, freq)	Compute the gammatone filter coefficients.
filter_signal(signal, sampl_rate, freqs)	Pass the signal through the gammatone filters
get_filter_coeffs(sampl_rate, freq)	Get the gammatone filter coefficients.
