No, different slopes from Eqium are not wrong… I was merely using that plug in as an example.
My main concern was that the range of the Renoise EQ can not get as close as that of other VST EQs
(This is sort of my original question on this thread)
You say that what I have proposed is a band pass filter… but is it really?
I have used two filters to achieve the effect in both plugins (Renoise and Eqium). These are Low Pass and High Pass… If this equals a Band Pass Filter, please accept my apologies (I guess it does, actually!)
If the filter is not going to change on the EQ, how about adding something like a detail window…
Thus…
Excuse the rushed job!
Yeah thanks for the link. This is pretty simple stuff.
Basically, I started this thread to try and get some background info on the EQ in Renoise, and have discovered some possible issues along the way. I am getting a bit closer to my intended goal, which is cool, so thanks everyone who has replied.
(If anyone can answer my original question, I would be very grateful too!)
Ah sorry, that thread was not a good example. I meant filter2’s filters -they do not seem to work in the same way as other filters. The hipass filter does not seem to remove bass frequencies as it should. For example, to get similar results to a 12db hipass filter at 300hz you need to set the Renoise filter to about 3000hz…
Here is a 909 kick, one channel has the Sonalksis TBK filter set to 12db hipass at 500hz, the other is the Renoise filter set at the same slope and frequency.
The Renoise filter is the green (top) line. For some reason it is not cutting the lows as much.
Here is the same test with 12db lopass filters. Renoise is the green line again.
This time the Renoise filter seems to be cutting more than the Sonalksis one… I’ve done the same test with other filters and they all seem to be very similar each other.
Yeah, it needs to be renewed. I use it a hell of a lot in tracks as it is very convenient to use in terms of operation. Once it gets sorted, balance will be restored in the universe
i’d definately go for the “in addition to” option.
filter2’s cutoff really feels and acts odd and sometimes i am really longing for a “proper” one, but then again, oddness can sometimes come in very handy.
so a “filter3” device (or whatever it might be called?) in addition to the filter2 would be perfect.
Or we could just bring back the old filter device and add the options to it that are yet lacking… (filter1 was not gone actually but you have to save it in renoise 1.5 and load it in Renoise 1.9)
The reason I don’t use Renoise’s filter is because the hipass doesn’t cut enough (or as expected). I tend to hipass every single sound to remove rumble and unnecessary low frequencies, and I find the current device unsuitable for this. I either end up layering a few filters in series, or I end up with leftover unwanted frequencies. For example, hipassing a kick with filter2 is usually not enough to stop it interfering with the sub.
The layering filters workaround prevents you from adjusting the sum cutoff frequency (and hearing the result in realtime), and it also attenuates frequencies around the cutoff too much unless you mess with the resonance… It’s just a bit awkward to do basic filtering.
Indeed, a set of ‘boring’ 12/24/36db hi and lo filters would be extremely useful.
The only problem i have with any of the filters is the highpass. It sound great for higher frequencies but i can’t get rid of the low end at all with it.
sorry i cant chip in on what to change/renew or modify,as im a new-coming renoise user(total-nOOb)so dont know the old renoise filters,but what about using the sonalksis(and other “standard”)filter types as reference and get the new filter(if you guys decide to make a new one)as close as those as possible??just an idea
(the time it took to write this,there had already been 4 more replys )
If it’s not possible to do that as a slider, then more presets (-12db, -24db, -48db, -96db).
I guess if the falloff is too step there will be artifacts? I don’t have much clue, but it seems that currently it’s not possible to really cut a frequency range off for good, at least not with a single filter instance.
The actual falloff of the frequency is rather artefact than a feature. To control it, you can add more “poles” to a filter. Some steeper filter algos cause some ripples, but Butterworth ones actually shouldn’t.
Ladspa plugins have a good quality configurable pole filters. And atleast by testing them with renoise internal spectrum analyzer they are very good and very very exact.
I’ll have to get some piccys in there…

… I’d like to be able to amplify any artifacts too
