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.

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.
