Comedi provide a useful API which make hardware abstraction layer, in order to unrestrict your code to a hardware vendor. > So the signal that I want to analyze are about approximate 60 Hz.

There are also some nice apps like Audacity which allow you to record signals and export them in a wav file witch is analyzable with GNU Octave. > I always think that what windoze can do, Linux can do it better.
