For splitting audio into frequency bands, you may want to try applying a
single filter, inverting the filtered signal and mixing it back with the
original. Now the output of the filter and the output of that mix are 2
complementary parts, adding up to the original stream again. You can
re-apply this technique to achieve multiple frequency bands...
Hope this helps!
