Thilo,
I would ask the question as to if your ultimate goal is really to totally and
completely separate the bands, or, rather, to control levels in a subtle,
musical manner.
If the former, then ask yourself what happens when an instrument or voice
straddles the crossover frequency, moving

Hello Thomas, Wen!
Thank you for the quick input on this.

the low and high band from the input and then

Thilo,
If you use traditional (analog-similar) IIR filters, you can create a simple,
first-order low-pass, then subtract that signal from the original to create a
perfectly-summing, complementary high-pass. This is what I usually do. To
create more bands, I just do the same thing again to those

When you use two-pole (second-order) filters, not only is the design more
complex, you also risk phase anomalies around the crossover point, usually
requiring you to invert the polarity of one of the bands.
this might be when it's useful to look up

Hello all!
I have implemented a multi-band compressor (3 bands).
However, I am not really satisfied with the splitting of the bands,
they have quite a large overlap.
What I do is taking the input singal, perfoming a low pass filter
(say 250Hz) and use the result for the low band#1.
Then I
