By combining even more shelf filters you can get as close as you want to the limiting case, which is what I would call a 'tilt EQ': a filter that has a constant (+ or -) slope (in dB/oct) over the entire audio range. This can be done _exactly_ only if the slope is an integer multiple of 6dB/oct. 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.
