I think you are just using some wrong coefficients for the left and right, thats why you hear the difference
Hmm... as mentioned it's a Linkwitz crossfeed filter in question. My attached FS schematic (so far) just tests if the 1st order low pass (LPF1 in Ruby comments) and the 1st order high shelf (HSF1 in Ruby comments) filters works correctly (now one in left channel and the other in right channel) . Then later I need to mix those filters to get crossfeed effect done.adamszabo wrote:I think you are just using some wrong coefficients for the left and right, thats why you hear the difference
And that Ruby code I use in my example schematic is what I would like to move to DSP component (which this thread is about).
Why I'm using polynomials the way I use there is just because of I'm going to use 3rd order 'matched' LPF implementation to get better high frequency response. As matching the LPF response in real time process needs quite a lot code, doing it this way (3rd degree polynomial/coefficient) maybe eases the CPU usage a bit ... .
