Wim Taymans 7d5940101b resample: tweak cutoff some more 
Increase the cutoff frequency for the lower quality modes. This should
give significantly better high frequency preservation at the expense of
more (but likely inaudible) aliasing.

Reduce the cutoff for the higher qualities in blackman and exp to
compensate the the wider transition band in those windows.

Increase cutoff for kaiser because of the sharper rolloff.
