Hi,
I'm looking for a platform for signal processing, who can be used in
command line mode ( matlab like ), but is based in low level code ( c or
c++ ), and block based signal chain. I wish i could find some kind of
front end to any standard plugin types.
It was desirable also that the standard plugin used is able to handle
data other than audio ( not so hard, i believe ), and in other domains
than time ( e.g. frequency, statistical, and weirdo like domains ).
Preferably it should have support for gui also, basically for plotting
graphics only.
thanks all,
Fabio

Have you look at Octave?
I think it can be expanded with c(++) modules.

That is correct.
It is a relativelu trivial matter to write C++ code which uses the Octave
C++ matrix and array libraries (basically everything that is written in
C++) to write extensions, much like the MEX files Matlab uses. The extensions
have a .oct extension.
Many of Octave's standard functions are written like this so you can grab one
of these as a starting point.

I'd use Python ( www.python.org ). It has many scientific 3rd party
expansions, can be extended with C/C++ and can
be operated from a command line.
You can quickly and easily implement your very own block based signal
chain since it's an object-oriented language.
Python syntax is not exactly
like matlab (whereas octave is really a matlab-clone),
but Python is _very_ easy to learn. With the Numerical Python
package you can do matlab-like matrix operations.
Haven't tried it, but ecasound has
a Python interface, maybe you could use
that to get audio plugins working?
