Subject: [linux-audio-dev] HowTo on DSP programming framework needed?

I am trying to determine if I should work on writing a HowTo "Linux
Audio DSP Research and Development". I believe that my current situation
at work is generic enough that other people will benefit from learning
about my solutions. I am still sorting through all the information and
projects on the web. It turns out to be quiet a challenge to determine
the best libraries and frameworks for this kind of work. But before I
invest time in the formal HowTo, I would like to ask if anybody knows
about a similar document that I might have missed and how much people
value such a new document.
I am thinking of covering the following topics:
1.) Support for initial research and development: Octave, SciLab ...
2.) Few Linux programming basics and selection of links (POSIX threads,
command line interface libraries, Makefile/compilers)
3.) Basic audio I/O and plugin architectures (ALSA, portaudio, file IO
libraries, LADSPA, JACK)
4.) Graphical libraries to generate realtime plots
5.) Optimized math (LAPACK++, ... )+ DSP libraries (sonicflow, libDSP,
SndObj, SPKit, ...)
6.) GUI libraries (Gtk, QT, Fltk, wxWindows)
Websites such as http://sal.kachinatech.com/ or http://linux-sound.org/
include an extensive list of projects. But there doesn't seem to be a
rating of the different projects and a help on how to put it all
together. http://scilinux.sourceforge.net/ is a good start, but doesn't
specifically address Audio DSP issues and doesn't provide an "put it all
together" view. That's what I would like to see being addressed in the
new HowTo.
I am also interested in learning (and maybe conducting a poll) who is
using which libraries/systems.
Your comments and suggestions are welcome!
