Hiya,
I dont think it was ever in doubt that xr is an amplitude? xr(i)
is the i'th the MDCT coefficient in the expansion of the original wave
form in terms of cosine functions with wave number i.
Not exactly... Term i in the mdct corresponds to sine/cosine waves number
i _and_ i+1, added
I dont think we should make this change. Preserving the amplitude
(and thus the actual shape of the wave form) seems more important than
the energy. Also, using fabs(i^8/3 -x^2) is an unusual definition of
noise that I have never seen in any of the technical papers.

hmm, I'm
