Somewhat different peaking EQ filter
I had a little DSP excercise which kept me busy for two weeks or so. The objective was to create a bell-shaped filter which is more concentrated around the center frequency than the common RBJ biquad, but at the same time has a flat top. This is what I came up with.
The schematic includes a 5-band demo equaliser (stereo, optimized). Feel free to use, integrate into your projects and modify if you like.

Re: Somewhat different peaking EQ filter
Very nice as always Martin!
It must be great to be able to think of a filter shape and behaviour and then be able to make it.
Thank you so much for sharing this and all your other amazing work.
