I'm using a biquad filter algorithm in my project. I got 3, 16 size variable arrays summing into one and then gets filtered.
Now i want to filter each array seperately and sum after that, which if the filter was linear wouldn't be a problem, but result is non linear after all.
Am I doing something wrong with this process or biquad's non linear in nature?
If latter is true, can you recommend a nice filter to implement in embedded C, and musical sounding as well? (Quality factor is a must)
I'm using this to generate coefficients
