I am trying to learn something of the algorithms used in
Vorbis. One of them is the "Modified Discrete Cosine
Transform" (MDCT). I have found a couple of books with brief
descriptions of the DCT, but almost nothing about MDCT.
(1) is there just one Modified DCT, which can be
expected to be the same whenever someone uses that
name, or does it just mean that you have changed
the DCT, but any number of people might have changed
it in other ways and called their own versions MDCT too?
(2) is there a recommended reference for MDCT, assuming
that name is unambiguous?
