its a HP filter, only... different. I would think this filtershape would be nice to have, when carving out stuff in the low end. At least, I would like to try it. Any ideas?

what's your vertical axis meant to represent?

because if its attenuation, its impossible to have two different levels of attenuation for the exact same frequency, which is what your curved part seems to be in its entirety.

That's just the 0db line...
The exact same frequency? What?
It's just an arbitrary HP filter cutoff at say 250hz. How did you manage to read the graph so wrong :roll:
And I said it was a HP filter didn't i? Yes I think I did say that, so where did you even get attenuation from.. Damn I'm flabbergasted by your reply tbh

the vertical axis refers to how hard the cut is, vertical line being a sharpest possible
you cannot also leave some of that frequency to pass in to the bulge.
the bulge is negative space.

exactly.

because its not clear what its a graph of, obviously. its frequency versus some unspecified thing.

you know what a frequency-response graph is, right? frequency versus amplitude (or amplitude boost/cut). well, that's what i'd expect to have seen here used to descrbe the behaviour of a filter.

so what is it?

i got attenuation from the usual frequency response graphs used to demonstrate filter curves, including HP filters.

It isn't a valid frequency/amplitude plot. You haven't provided any information about what other kind of graph it might be.

So the natural assumption is that you drew a frequency/amplitude plot incorrectly.

Subject of first this thread asks about 'filter curve'

Here's the kinds of image google returns for 'filter curve'.

any clue there as to why i might be asking if the height axis is attenuation? no?

I think the question is in the wrong forum. "Spells" would be the right one. Harry or more likely Hermione might know the answer...

as a wizard, i find this offensive.

Which bit? The bit where Hermione is smarter than you? :hihi:
