lpread will give you pitch, amp and a "spectral index" consisting of
series of multipole filter coefficients frames that are passed on
internally to an lpreson ugen. You must of course analyse the soundfile
with lpanal. You can stash these functions (except the filters of
course) into a function table by first wrtting them out to a file via
the kdump ugen. You then reopen into a table with a gen01.
