:-) Digital emulations of well-known analog equalisers have become a genre of their own... Usually the 'good imperfections' (noise, distortion,...) are emulated as well, as if the creators of those EQs actually added them on purpose. I can't imagine any of the designers at e.g. Neve or SSL ever doing that - they went for the best technical specs they could have. Not that all equalisers are equal, far from it. Some of those classic designs had some unusual features such as higher order shelf filters which are actually quite nice to have. I wrote an equaliser having those some years ago (not yet published, maybe I will some day), and it has become my 'workhorse'. You can see some of the frequency responses here: <http://kokkinizita.linuxaudio.org/linuxaudio/shelf2filt.html> It's possible to obtain almost the same with a 'classic' parametric + shelf EQ, but it requires using two or three sections in a coordinated way - not very practical. Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.
