I want FilterPro to design a filter to make pink noise from white noise. This requires a low cutoff frequency and a stopband rolloff of -3 db per octave. I have not been able to make FilterPro do this. Is it possible? If so, how?

FilterPro is based primarily on using second-order active filter sections, which are -20dB/decade or -6dB/octave. That's why it's not simple to get FilterPro to do a -3dB/octave filter.
This site shows a design for a pink noise filter, hope that helps.
