Hello,
I just released polarbear. I had the code lying around, and just merged
it with the jack/alsa i/o code of tapiir. Note that this is the first
public release. I did not test it thoroughly, and I am not sure if the
GUI is obvious enough (it should be if you are familiar with complex
filters), so any input is welcome.
polarbear is a tool for designing filters in the complex domain. Filters
can be designed by placing any number of poles and zeros on the z plane.
From this the filter coefficients are calculated, and
the filter can be
applied in real time on an audio stream.
polarbear can be found at
http://www.iua.upf.es/~mdeboer/projects/polarbear/
For the (far) future, the idea is that polarbear and tapiir can work
together, in the sense that the filter coefs calculated by polarbear can
be used to control the gains of tapiir. maybe polarbear and tapiir might
even merge. that would be some animal :-)
