Something that might allow me to write equations, >stimulate the filter, see the results in a GUI? i guess a general scientific tool like octave (a free alternative to matlab, the de facto standard among scientists) would do all you may possibly want to do, although learning the language might require some time. i don't know of any "ready-to-go" tool for dsp where you just put the coefficients and you get the poles, impulse and frequency response, etc. i would be very interested if anyone knows such tool. if you want to work with audio, you can easily program any filter in csound or any other software synthesis language, like pd, common lisp music or whatever (i know csound). then you can "see the results" using an analyser/visualiser like sonic-visualiser, for example.
