i guess a general scientific tool like octave (a free alternative to |
| 8 |
matlab, the de facto standard among scientists) would do all you may |
| 9 |
possibly want to do, although learning the language might require some |
| 10 |
time. i don't know of any "ready-to-go" tool for dsp where you just put |
| 11 |
the coefficients and you get the poles, impulse and frequency response, |
| 12 |
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 |
| 15 |
csound or any other software synthesis language, like pd, common lisp |
| 16 |
music or whatever (i know csound). then you can "see the results" using |
| 17 |
an analyser/visualiser like sonic-visualiser, for example. |
