Hi, is there a simple way, create a first-order filter using your code?

Sorry, the implementation is based on https://exstrom.com/journal/sigproc/dsigproc.html

only 4,8,12,16 is supported for band pass, and 2,4,6,... for low pass and high pass.

If you really need a filter that has an odd order. You can try a similar implementation from here. https://exstrom.com/journal/sigproc/alpbw.c
