Are there any Public Domain DSP libraries or open source efforts that exist?

DSP is an interesting choice.

Specific is good. Have you looked at the Intel site?

Or the ATLAS BLAS libraries, probably on netlib.
and FFTW and DJBFFT, of course.

It's some time since I used it and I don't remember what (if any) routines
specific to DSP were supplied, but I found LAPACK very useful. All those
SVDs and EVDs that many tecniques of "modern" DSP need...

I think I have a related question.
I operate in a Windows XP Pro enviroment
I have a LARGE amount of raw audio data in WAV format.
The frame size of interest would range from ~.02 sec to .1 sec.
I would like to generate spectra of this data on a per frame basis.
1. amplitude or power is a moot issue
2. speed is secondary [ I'm using stored data ]
I have two constraints:
1. minimal financial resources -- this is by denotation rather than
connotation an "ametuer" project.
2. I don't really have math background to develop my own solution,
but have enough to "almost" ask the "right" questions.

Get the demo version of ScopeDSP from http://www.iowegian.com and see if
it will do what you want. If it does, either buy it -- it's not
expensive by my standards if you decide to buy, but if it works for you,
ask here if there's a free or cheaper program that does only the task
you need.

I've heard some rumours about a matlab clone being available somewhere?
Octane, Octave or something like that. Does anyone know about this?

See http://www.dspguru.com/sw/opendsp/mathclo.htm for more information about
"Octave" and other Matlab clones.

I got the demo a while back and it can do a lot of what I'm looking
for. I asked in this thread just incase someone had come across
additional programs of interest.

Scilab link on that page is broken.
http://scilabsoft.inria.fr/ works however.
That page also provides links to hard copy books on using Scilab.

Octave and Scilab are free. Google for them. There's another I don't
remember mentioned in a relatively recent thread. That thread also
discussed their relative merits.

But does anyone have working link to downloadable docs.
The online links work, but i'd like local copy of docs as a prictical
matter if I'm going to try to learn how to use.

There are docs that come with the Scilab download. Last I looked, they
were adequate, but would have benefited from improvement. Maybe they've
been improved.

In addition to a language based clone of Matlab, e.g. SciLab, Octave, or
Rlab,
we have something else that is a functional based clone.
Such clone are not compatible with m-code level but basically realizable
with similar form
because it can be consist of libary of C++ language. In practive, I had many
helps from them
while I simulated a MIMO W-CDMA link sytem including turbo-codec.
That is IT++ (https://sourceforge.net/projects/itpp/).

My introduced IT++ must have been very powerful tool to me.
So, let's try it.

There is an extensive "Help" function in download package.
It gives syntax information.
BUT, overview/introduction for the uninitiated.
http://scilabsoft.inria.fr/doc.html
has EXTENSIVE documentation including:
* Introduction to Scilab
* Communication Toolbox Documentation
* Signal Processing
* Lmitool: Linear Matrix Inequalities Optimization Toolbox
* Metanet User's Guide and Tutorial
* Scicos
* Scilab's Internals Documentation
* HOWTO's Scilab
* Scilab's demonstrations
* Intersci
* Inline help pages
[ This is the Help system contents and is all the
documentation that is in the download. ]
They are individually available in HTML, PDF, Postscript, and LaTex
format. [ most available as HTML ]
What's not working are links at bottom of page to ftp all the manuals
in desired format.

It's largely (but not completly) compatible with Matlab. Any Matlab
tutorial will help, as long as you remember that the correspondence
isn't exact. From far enough away, they look the same. Graphics is the
biggest difference. I'm told that Octave adheres more closely but is
less complete. Or something.
