Yes, that's another main problem.. the maths. I hope to get the ALE software to see if it is possible just to store some coefficients and not calculate them within the pic. However (I think), all parameters change (all 5) just by changing one value (for example the gain) of a filter.. so every coefficient has to calculated, not only one.

Hm... I don't mind to spend some time working with the TAS3002 as it seams to be a very interesting IC and still easier than a "real" DSP, but first I should know how difficult it is and whether it is possible with a pic at all... I have a free C-compiler, but it can only manage 16 bit variables.. so thats the first border.. difficult as a 4.20 data format is needed.
