completely cutting out certain frequencies

[bloodbit]

Hi guys, noob here.
For the longest time I thought by eqing I was cutting out unwanted frequencies completely.
I realized today that was not the case and was wondering if I could be either configuring the equalizer wrong or if I need to use a specific plugin to do this. I think I want something with a really steep slope, removing unwanted frequencies completely if that is even possible. I first looked into engineer's filter but they only have 32 bit versions, which don't work on my 64bit version of ableton. I've messed around with filters but the unwanted frequencies still bleed through.
Picture is attached to show you an example, the spectrum analyzer after the EQ shows the higher frequencies still coming through after cutting them out.
Thanks guys!

The only way to completely eliminate any trace of a frequency with an EQ, is to notch it out (unless you could DC as a frequency). That's just how filters work; you can reduce it below the threshold of hearing, but never remove it completely.

Here's what matters: do you still hear it? If you don't, then who cares?

[bloodbit]

I definitely cant hear it but the thing is with 30+ channels all contributing wouldn't all those bleeding frequencies contribute to muddying up the mix?

[Wontolla]

Not if they're at -40dB compared to everything else. That's a factor of 100. It just doesn't look that way because of the scale.

AHHH I see I neglected the scale thanks man

You can do this with a linear phase EQ, but generally this should be avoided because there are quite a few issues that come up with linear phase EQs, the most obvious one being that they create quite a bit of latency on w/e sound you're EQing.
If you really want to try though, Ozone has the capacity to do this, and if you don't have ozone you can always do a quick "free linear phase eq vst", though i can't vouch for anything that comes up.

found something interesting
It's called engineers filter (http://www.vst4free.com/free_vst.php?id=951). It's free
It's meant for steep (and i mean like 90° steep) eq cuts for mastering, it has different "methodes", eg Inverse Chebychev or Elliptic. I mostly use one of them because its the steepest cut and if you look at tracks from big labels(let's say spinnin or monstercat) you can see the spectrum on the top end looks like they were made with these methods.
