14 | function: normalized modified discrete cosine transform | ||

17 | |||
18 | Original algorithm adapted long ago from _The use of multirate filter | ||
19 | banks for coding of high quality digital audio_, by T. Sporer, | ||
20 | K. Brandenburg and B. Edler, collection of the European Signal | ||
21 | Processing Conference (EUSIPCO), Amsterdam, June 1992, Vol.1, pp | ||
22 | 211-214 | ||
23 | |||
24 | The below code implements an algorithm that no longer looks much like | ||
25 | that presented in the paper, but the basic structure remains if you | ||
26 | dig deep enough to see it. | ||
27 | |||
28 | This module DOES NOT INCLUDE code to generate/apply the window | ||
29 | function. Everybody has their own weird favorite including me... I | ||
30 | happen to like the properties of y=sin(.5PI*sin^2(x)), but others may | ||
31 | vehemently disagree. | ||
