I’m making an equalizer for my thesis project and I was wondering what type of filtering is best for a real time EQ? I followed how Daniel made the Frequalizer, but from what I understand that plugin uses 6 IIR filters and that’s fine, but not ideal, I have been told. I am also looking at the fabfilter equalizer and it has an unlimited amount of filters you can add to it which I guess is pretty cool.
If there are some example project or built plugins code I would be interested to see them even if they do the same thing.
I’m not really avoiding the IIR. Just asking around to see best practices and if I could find an equally easy to implementation on the filters and potentially better ones.
FabFilter is like my ideal and I was also wondering how they did it.
Thanks for the input I’ll definitely check the resource for my final documentation and follow the code along to better understand it.
When you are searching for a better filter you should maybe start in which ways the filter you are looking for should actually be better? Computational overhead? Latency? More linear phase? Higher filter orders?
I’m by far no filter expert (I have the luck to work in a team with some of them) but what I can definitely say is that filters are always better in one dimension and worse in some other dimension at the same time. You mentioned FabFilter two times, so what exactly do you like about that EQ that makes it superior to you?
@daniel I’ll keep looking into it, take deep dives into available examples.
I’m not trying to earn any money from it, it’s just for my project and to get accustomed to C++; potentially to help me develop for this path.
I’m quite the beginner, I don’t have the luxury to be super picky about how I implement most stuff.
I like about fabFilter that I don’t even notice there’s a compromise in an area. It seems a very good all rounder I guess.
there is no visual delay on the analyzer(very smooth) like, for example, ozone dynamic EQ.
the interface is very well done, the visuals of it are also very smooth
as far as I can tell there’s no issue with any of their filtering
I guess it’s just the best I’ve seen
