Sure, but it's hardly only a problem of the digital domain :-) > You can obviously do that, but you'll need a hell of a precise, with > tons of bits and high dynamic range DAC.

DACs are now offering specifications beyond the realities of analogue support circuitry and if you want to read up about a nice mic do a search on the MKH- 800 (digicams aren't expensive).
