an iterative root polisher (CACM algorithm 283). It *is* possible
to confuse this algorithm into not converging; that should only
happen with absurdly closely spaced roots (very sharp peaks in the
LPC f response) which in turn should be impossible in our use of
the code. If this *does* happen anyway, it's a bug in the floor
finder; find the cause of the confusion (probably a single bin
spike or accidental near-float-limit resolution problems) and
correct it. */

function: normalized modified discrete cosine transform
power of two length transform only [64 <= n ]
last mod: $Id: mdct.c 16227 2009-07-08 06:58:46Z xiphmont $
Original algorithm adapted long ago from _The use of multirate filter
banks for coding of high quality digital audio_, by T. Sporer,
K. Brandenburg and B. Edler, collection of the European Signal
Processing Conference (EUSIPCO), Amsterdam, June 1992, Vol.1, pp
211-214
The below code implements an algorithm that no longer looks much like
that presented in the paper, but the basic structure remains if you
dig deep enough to see it.
This module DOES NOT INCLUDE code to generate/apply the window
function. Everybody has their own weird favorite including me... I
happen to like the properties of y=sin(.5PI*sin^2(x)), but others may
vehemently disagree.

/* this can also be run as an integer transform by uncommenting a
define in mdct.h; the integerization is a first pass and although
it's likely stable for Vorbis, the dynamic range is constrained and
roundoff isn't done (so it's noisy). Consider it functional, but
only a starting point. There's no point on a machine with an FPU */
