Stuff like that is in the archives. Quoting from Alan McDonald's mail of
March 11th 2002:

>From vorbis/lib/modes/psych_44.h:
/* lowpass **************/
static double _psy_lowpass_44[11]={
  15.1,15.8,16.5,17.9,20.5,48.,999.,999.,999.,999.,999.
};

o q0=15.1, q1=15.8, q2=16.5, q3=17.9, etc...

<p>To answer your question, no lowpassing happens at q 6 and higher, while
anything >= q 4 doesn't have noticeable lowpassing.
