Audacity is definitly decent, though I am not sure if it will run on Windows or not, but Gnome Wave Cleaner is better suited for this project from what i have heard. But chances are it will only run on linux(Gnome dependancies) so Audacity is definitly next up for it
But a line in depending on the port might still be a stereo in(Actually usually is). And connecting a line out from a cassete deck to a line in on a computer will usually get the levels close to the original source if not dead on. If you are using a Mic in, make sure you turn the gain(Level) all the way down, its the only way youll be able to get close really. If you are using a headphone jack on the cassete deck to transfer instead of a line in, adjust the levels there as well as needed(But I highly reccomend sticking to the line out/line in method)
