I feel a bit amatuer asking this as i should of a long time ago.

Basically no eq or filter is cutting it off how i would like. I need something like a "-infinityDB" HP filter to place right where i want to cut off so it would just be the steepest cut off imaginable?

EDIT: maybe something steap/free?

Try the Kjaerhus GEQ-7 with the 48db filter option. That's as steep as a cutoff as you'd prolly need.

oh i forgot to add cheap/free

You could always try chaining two 24db filters together.

I second the GEQ-7. The freebie Filter might do the same thing - it's modeled on the same filters as the GEQ-7, and you only need one for this. www.kjaerhusaudio.com

You try something like CurveEQ or something with a controllable curve to see if you can get what you want instead? If a certain 2/4/6/8 pole cut off ain't working, try one you can control. If not, consider the bass you're hearing might be your room too.

Equim might be a good option too.

Wouldn't KTAudioHealer work?

Bugpass might be good for you

An eliptical filter provides the steepest cutoff I know of (nearly looks like a right angle), however I have only seen that available on the Cambridge EQ (UAD-1). Depending on the order, Butterworth and Bessel filters get much steeper than 48dB/oct, but I have never seen these in a free EQ either. Voxengo Elephant has a switchable Butterworth/Bessel HPF built in, and that plugin is pretty affordable. I am assuming you already tried this one:

since it was in the thread you mentioned. How did that one sound?

Nothing but a Parametric / notch filtered EQ, should be used,
when your dealing with sub-Harmonics.

Wow, shows MY ignorance.

I always just thought you could grab a non-resonant high-pass filter and plunk'er down at 10Hz or whatever.

I'm curious to learn more, for my own personal reference.

actually bug pass is the effing best BP/BR filter ever (not for cases like this but in general).

Chase, are you recording fart noises again?

What do you use to cut subharmonic frequencies.
