It appears that audio processed through mbelib leaves undesirable low frequency components. The voice understanding can be improved with a high pass telephone type (> 300Hz) filter.
In fact the IIR filter used in the interpolator cat be set to be either lowpass therefore without this additional filter or bandpass therefore with the additional filter. It is just a matter of coefficients that can be calculated with Python scipy.
