I don't use VisualAudio, so I'm guessing...

I used SciLab once to calculate IIR filter coefficients where MatLab 
failed because of its limited floating point precision 
(extreme Fs/Fc ratio).
SciLab performed almost equal, maybe better with respect to precision of the
results.

However, SciLab is not so much compatiable to MatLab, that one might expect.
I would guess that the combination of both tools uses Matlab's automating
capabilities which have not been built into SciLab.

Quick answer: Yes

Not so quick answer: Maybe, but it depends on how much 
knowledge/code/etc you need to migrate. Scilab and Octave are close 
enough to matlab for most tasks, and if you don't have an existing 
codebase then you don't have much to lose. Both lack some of MATLAB's 
more powerful features, though, and some of the toolboxes.

If you are looking to start afresh, maybe a glance at Scipy and 
Matplotlib for python would be appropriate.

Don't know but I have tried both SciLab and Octave via MatLab conversion 
routines, wanted to calculate WD filters. Didn't work at all. It was 
really frustrating, only got tons of error messages. So, I went back to 
the trusty old DOS programs which work like a champ.

Quick Q
Can this be used as a replacement for MatLab in VisualAudio filter 
development?
