bASS_BUMp: for a nice round bottom...
this is NOT a resonant high pass filter...
it is a high pass filter with a "bump".
what's the difference ?
one adds "resonance", the other adds "roundness".
give it a try, you will hear what i'm talking about...
check out this frequency response comparison of my bASS_BUMp JSFX (green) and ReaEQ (red), both set to about +3 dB "resonance"...
this is a very sexy curve, indeed...
i have attached the JSFX in this post, please give it a try and tell me what you think...
thanks
edit:
here's another frequency plot showing the curves for (Fc = 55 Hz) bump values of 0, +1.5, +3, +4.5, +6 dB...
the parameters are self explanatory, really, but i will clarify here...
frequency = center of bump (+/- 5 Hz)
bump = boost amount (+/- 0.25 dBFS)
output gain = "clean" gain (no saturation or clipping) to adjust output level
64 bit float processing so there is no need to worry about input/output level or clipping.

Yes this can work quite nicely on some things. It's what BOZ's bark of dog and PA's bx_subfilter does.

Bark of Dog is a (typical) resonant filter, it looks exactly like the ReaEQ spectrum.
this filter i made is a little different, it's has a greater bandwidth for the boost, so it does not "ring" like a resonant filter and it has a "smoother" phase response.
you could (easily) duplicate this with ReaEQ and two(?) filters, but (like Bark of Dog) this is meant to be a "one trick pony" and easy to set/use.
i haven't tried the bx_subfilter, so i can't comment on what that filter actually does/is, but i would bet it is a resonant filter.
thanks for trying/commenting.

Thank you,
i will give it a try.
BTW: What tool do you use for the graphs? The first one is SPAN, an the other?

i have an older version of Fuzzmeasure (mac only, free demo)...
http://supermegaultragroovy.com/products/fuzzmeasure/
you can get similar graphs with R.E.W (free for mac & pc)
http://www.roomeqwizard.com
both are room/acoustic measurement software, but you can import/capture an impulse from anything and it will give you the data/graphs.

C'mon man
Of course it's a resonant filter, it's just got a fairly low Q.
Electrical engineering 101, Butterworth, Chebyshev, Bessel anyone ?

but...i don't hear no resonances
but seriously...
ok, maybe i should have been more clear and said "this is not your typical resonant filter like a moog or something"...
you can not duplicate this curve/bump with any (single) filter by adjusting the resonance/Q. the Q/gain relationship is totally different. so this does not "act" like a "typical" resonant filter plug-in.

By the way, your plugin looks useful, so no diss from me, good job !
Duplicate with a single ReaEQ filter ? OK maybe not.
However you can simulate this with a high pass filter and a bandpass filter tuned to the similar frequencies, I did this one in under a minute:

yeh, it's basically 4 one pole filters...hard (impossible?) to replicate with just one filter, but you could do it with 2 filters, easy.
it consists of:
a one pole LPF*gain + one pole HPF = "cross-over" / acts as a shelf/bump (green trace)
then two one pole HPF = 12 dB HPF (blue trace)
(they all share the same Fc.)
red trace = final filter
so it's pretty simple, but different than the same old filter.
honestly, i just started a thread about it because i thought the name/title i came up with was pretty funny...
thanks for stopping by

Oh yeah, don't get me wrong, you've given us a cool little tool !!
And a graphic artist could have a ball with the letters in the name as you say

Have you figured out what goes on with reafir? > this can give totally customized shapes.
When I play with it- I set the noise floor and ceiling levels to +/-150db.
It's a special tool because of the edit modes and fft sizes.
Can work as quite nice partial resonator and subtractor.
