An auditory filter bank implementation in Python

Contains implementations of an Equal Rectangular Bandwidth (ERB) filter bank and a linear filter bank.

Based on Josh McDermott’s original Matlab implementation in the Sound Texture Synthesis Toolbox

Filter banks are a very useful time-frequency analysis tool. A nice alternative to your standard spectrograms.

See ‘example.py’ for a demo.
