TypeError: '<' not supported between instances of 'NoneType' and 'int'. in spafe.features.ngcc.ngcc()

[zakaria-kabir]

spafe.features.ngcc.ngcc(....., low_freq: [Optional] = None) but doc says, low_freq defalut is 0. Also no where in the function the value has been set.
This occurs error in: (if low_freq argument not passed)

• gammatone_filter_banks(nfilts, nfft, fs, low_freq, high_freq, scale, order, conversion_approach)
  180
  181 # run checks
  --> 182 if low_freq < 0:
  183 raise ParameterError(ErrorMsgs["low_freq"]) *

This is a good catch. I already found the issue and I will be releasing the fix asap.
Thank you for reporting ❤️
