The error occurs when there is a zero in the array :

spec[WR_upper_f_limit_idx:]

a working fix is replacing the line 217 with :

 above_WR_spec = [value if value == 0 else np.log10(value) for value in spec[WR_upper_f_limit_idx:]]

Fixing isse AudioCommons#12 where np.log(0) caused a RunTime Error
a1c66e2 
When there are zero values in the spectrogram array (the intensity is null) the np.log10 raises an Error (because log10(0) = -inf). Because the log10 is used to reduce the range of the values, when a value is zero, zero should be returned.
