Cohen-Daubechies-Fauraue (CDF) 9/7 wavelet-transform
Hello,
I have to make use of the Cohen-Daubechies-Fauraue (CDF) 9/7
wavelet-transform, but have not found these biorthogonal wavlet in the
released packages waveslim, wavethresh or wavelets.
Is there any package doing this transform?
Or can anybody send me the function doing this? I would be very grateful
of that.
Thanks
Annika

problem in waveslim library?
This code consistenly segfaults for me. Can someone please take a look
and tell me if the problem is due to something I am doing or is there a
problems with the dwt (idwt) functions in the waveslim library.
Thanks

Impulses
After playing with the vorbis code for a while and doing tons of hacks and
analysis on it, I've found it to perform very poorly with impulse signals.
The MDCT seems to cause lots of spreading, and it seems to result in much
worse impulse performance then mp3.
What is the current plan on handling this? Will a smart quantizer be able
to avoid it?
I've been looking at various ways of

initialize expression in 'quasi' (PR#8486)
This is not so much a bug as an infelicity in the code that can easily
be fixed.
The initialize expression in the quasi family function is, (uniformly
for all links and all variance functions):
initialize <- expression({
n <- rep.int(1, nobs)
mustart <- y + 0.1 * (y == 0)
})
This is inappropriate (and often fails) for variance function
"mu(1-mu)".

album portion of the tags request
I wanted to post publicly my problem with Jonathan's proposed album
requirements. Although I do apologize, since this thread is too big already.
The idea that as a requirement one should be able to identify the exact CD
a track was ripped from is not a valid requirement in my book (not for the
tags at least), and I hope I can explain why. Without knowing the exact
way Jonathan wishes to
