BiFreq BiPhase modules

[Rocko]

Hi,

The stock Equalizer example (originated from Synthmaker) can show the user the 'frequency response' as well as the 'phase response' of the chosen filter.
This is done by two stock modules: BiFreq and BiPhase which I can not 'jump in' to see how they work.

So, how do these modules work? Let's say I want to code it myself in 'blue code', is that possible?
What is the theoretical line of thought for building such vectors?

Is it based on pole-zero assumptions ?

Thanks,
Rocko

If you want to know what's going on in the BiFreq/BiPhase, you can have a look at my Filter Construction Kit:
http://www.dsprobotics.com/support/view ... f=3&t=1234

It contains all the calculations in Ruby, the "Linear Filter Response (MyCo)" Module does exactly the same as both of the primitives.

Although I'm not sure why you would want to do this in streams. It's a hell of a calculation...
