What do you use to cut subharmonic frequencies.

[Hunter]

Why don't you think it's good, Chase?

I said I loved it, but the latency really bothers me and makes it useless on things like drums in fast-paced electronic music.

Chase are you doing this for your drums or the bass part? I wouldn't have thought you'd have too much bass to get rid of on the drums, depending on your kick sample. You could prpbably start dropping your kick off below about 70-80 or so.

The trouble I have is with bass - getting rid of the sub-50-60 Hz stuff, as I tend to have pretty pumped basses there can be a lot to get rid of. Bugpass shouldn't affect basslines too much in the writing phase though I haven't tried it yet...

Tried NyquistEq for this Chase? (or anyone for that matter, I'm curious about how steep it can go)

I recall someone sugesting eqing a Hipass way down at 35 Hz or so followed by a Low shelf at 50-60hz.

I usually follow an 18th order Butterworth highpass filter at 28 Hz with a gentler 6th order filter in that 50-60 Hz range. This avoids a case where placing just one very steep filter further up the low bass region could exhibit the potential for audible perception of phase anomolies.

You mean 18dB and 6dB don't you? Because an 18th order Filter would give you about 54dB, which is very very steep.

Yes Christian. The two terms are casually, and mistakenly interchanged. You have the correct reference. My bad.

They are Peak EQs, so you can't cutoff below a given frequency, but only attenualte the selected frequency. Gain at DC usually equals 0, but i'm not sure about the explicid implementation.
At least at nyquist frequency the gain may not equal 0 for high frequency peaking filters, that's the special thing about it.

OT: the Myth Busters did a show on the 'brown note' and try as they might, they couldn't reproduce it. But that doesn't mean that being hammered with sub frequencies won't 'shake something loose' if you're already feeling a bit out of sorts.

Hi betabugs folk, I've been having a mess around with Bugpass and whilst it sure does chop off frequencies sharply, I'm not sure the frequency it displays when you move the slider is very accurate.

I noticed that the bass was dropping off very sharply even when the low slider was set to eg 40Hz (Which is very deep bass indeed). I then got a nice frequency rich waveform and used the Bugpass sliders and VoxengoSPAN on a fast setting, and found that the cutoff frequency for the low slider is actually a lot higher than what the figues on Bugpass say it is. Same for the top slider. I would post some audio/screenshots but I don't have FTP at the moment.
I'm not bitching jsut pointing it out - I might be being silly. I'm using it in normal not notch mode, downlaoded today.

Apart from that it does exactly what is says on the tin! Nice.

from what i remember the cut off freq of a filter is defined as the point where its -3db.

also being a dnb producer myself, most subs ive encountered range between 37-70hz. if i was cutting under a sub itd most likely not be above 25-35hz, for drums more like 60hz.

Hey Hunter, thanks for taking a look. It's not really my domain to be honest with you, but I'm sure Christian will either confirm your findings, wm's statement, or provide a more detailed (and possibly crazy-technical, you just never know with Christian!) response.

Thanks for the test, i've made a screenshot of my plugin analyser testing the bugpass with a sweep. Here is the result:
But maybe there is an error in the samplerate routine. What rate did you use?

Hi Christian

I'm at 44,100.

It seems that the actual cutoff values are ~4 times higher than stated on the plug?

I tried it in both FL and SOnar4 incase I was doing something silly...

I can't upload pics at the moment as I can't get into my email to get my ftp details but the cutoffs as heard are pretty much exactly four times the value set on bugpass. Hope that helps.

Does look like a wicked lickle plugin though! I downloaded the other Bugs too and really like the stereo enhancer and the chorrosive one

Cheers

The reason I tend to drop off my bass around 40-50 Hz or so is that I simply can't monitor whats going on down there at all, so would rather play it safe and get rid of it all rather than have some energy sapping rumble going on that I don;t know about.

I tend to drop my drums off below about 60-80 though, also.

Hmm, don't know. Will check this next week.

Something's up, Hunter. I've just had a peek using debutante's Inspector method, and cutoffs seem to be around the same as what Bugpass indicates. Now, my test isn't as 'scientific' as testing with dedicated tools would be, but I certainly don't see 4X a difference.

Remember, of course, that most of these tools are scaled. Which means that one physical unit of measurement (ie. a centimetre on your monitor!) could be 5,000 Hz difference higher up, but only 5 Hz lower-down. So, depending on the tools used, the curve will appear 'rounder' and the slope less steep in the subharmonic range.

Or, at least that's how I understand it. I could be wrong.

Hmm OK well its probably something funny on my machine then, no worries.

here are the piccies:





My ears also agree with the pics.

System: AMD 1700, W2K, Audophile24/96,

Hopefully its just me being silly somewhere...

Probably. Tried the same by myself:
But I have found something stupid in the code. Maybe i'm wrong somewhere. Will fix it next tuesday.
