   I am after a digital filter that has an arbitrary response. I want to 
implement a digital graphic equaliser for high quality audio. I have had
suggestions of approaches by multiple band pass, but I believe it to be
quite possible to have one where the coefficients are calculated in the 
frequency domain, which seems sensible. Anyone know of a good algorithm for
this? 

   I would also be most grateful if anyone could give me some info on filters,
FFTs etc that are intended for REAL data! This seems almost impossible to find-
doesn't anyone use ADCs!??

			Thanks in advance,

						Marcus Bointon.
