To put this in perspective: To have a dynamic range corresponding to roughly 27 bits, an analog signal needs to have full scale power of 1 Watt (since thermal noise in 20 kHz is around -161 dBW, and 161 / 6 ~= 27). For 32 bits you'd need more than a kilowatt at the point of conversion between analog and digital and in every analog signal point before or after. 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.
