function: normalized modified discrete cosine transform
|

power of two length transform only [64 <= n ]
|
||||
|
||||
|
||||
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.
