Is maximal value of “length of filter” for “equalizer” effect limited by something? Can I increase this value? Where in source code is it?
Thanks! And sorry for my bad english.
It can be changed in src/effects/Equalization.cpp, but note that as the filter size increases, abrupt changes in the filter curve will tend to cause more “ringing” at a frequency close to the abrupt change. To avoid ringing you shouldn’t go much over the current max.
Update: I’ve just had a quick look, and although the maximum filter size limitation can be removed quite easily, all sorts of weird problems occur once the size goes above about 10000, so unless you want to spend a lot of time on this, it is probably not worth the effort.
Why do you need a larger filter size anyway? There may be a better type of filter to use.
