Well, I have some bad news for you. (you may want to second-source this
though).

In the little experience I've had working for a small tech drawing firm
(wich used ACAD heavily), I've been told that the ACAD .dwg format is
proprietary and ``secret''(1) (though someone somewhere might have hacked it).

However, the .dxf format is not. Its format is even described in the ACAD
reference manuals.  The drawback is that it is a text format, so it must be
parsed (which means that it's S-L-O-W).  It also tends to gobble up space
for large drawings. (.dxf format was put into ACAD to exchange drawings
between different drawing/drafting/jotting software).

That is only true for objects covering a large field, with soft
edges. In fact, if you have a small object or a sharp edge, it
is not true due to chromatic aberration in the eye. The effect is 
very striking indeed and both psychedelic and disconcerting when viewing
the compound color, especially with very red reds and very violet 
"blues".

I have received a 1991/1992 catalog "Computers in Science and Art"
from Media Magic.

This catalog has books, magazines, journals, videotapes, laser discs,
and software for the following subject matter:

fractals, scientific visualization, computer graphics, computer animation,
chaos, computer art, virtual reality, mathematics, artificial life,
satellite imaging, astronomy, hyperbolic space, artificial intelligence, etc.

I'm impressed by the selection!, from Rheingold to Langton, Siggraph to
Senate hearings.

I have never had dealings with this company.

I am not recommending this book - just mentioning it because a colleague
just came back from the bookstore with a copy of it.  As you might guess
from the title, it contains a lot of plug-and-play DSP code, and minimal
discussion of the routines.  The book comes with a PC format disk with
the source code.  I remember seeing a comment on the net from someone
who had criticisms of this book, but I cannot remember what he said.

Hello Bob,

I have been working at improving on a system to track a signal that
contains noise.  The work that we have started with is:

Selfperturbing Recursive Least Squares Algorithm with Fast Tracking
Capability, by D.J. Park and B.E. Jun, in ELECTRONICS LETTERS,
12th March 1992, Vol. 28 No. 6.

The idea is to estimate the input signal using a 10 term filter.
The system does not seem to react well to larger noise levels and
we are working on improving it in this area.

I don't think that this would help to seperate voice and music, but
we hope it will remove background and machine noise of any gain 
from the voice/music signals.

The above reference is a good starting point.  I do not know what
we are going to do with our findings yet but the summer job ends
Sept. 1st.

Good luck,

	Richard

What you say is true for MatLab versions < 3.5i, but MatLab 4.0 is supposed
to handle all the data formats you mention.

This can be done with MatLab 3.5i too.  There are demo routines provided
(e.g., engine.c) that allow MatLab to communicate with other routines via
UNIX pipes and/or files.

I haven't tried controlling our Exabyte drives from within MatLab, but I don't
see any difficulty in doing so.  Using the MatLab "engine" and UNIX shell
escapes (!), it should be doable.

Of course there are also vast amounts of MatLab code available (e.g., netlib).

There are many things I like about MatLab 3.5i (I'm waiting for 4.0).  However,
it doesn't do everything.  I'm surprised that a couple of the other systems I
use haven't been mentioned yet in this thread.  For 1-D signal display, I often
prefer Entropics' ESPS/waves+.  For symbolic signal processing, I use
Mathematica 2.1 with Brian Evans' Signal Processing Packages 2.71.  Although
MatLab, Mathematica, and ESPS/waves+ are expensive, hopefully you could
convince people, how could you not afford to have them?
