You put it better than I did. That's exactly what I was thinking.

That makes sense to me. I have it in my lecture notes too.
But why does the filter in this picture look so bad: >>11321080
As far as I know, filters get less wavy at an higher order, so I assume if the order was really high, it would almost be rectangle shape?

And another thing, the screenshot in my post are the low pass filter options that I can select in audacity for audio editing.
Are those 5 options just different orders of filters? Why can't I just use something like order 1,000,000 and computer for a few minutes to get the perfect result.
