david, If you want to get really close, as in with a few cents of a pitch, the only thing I know of is an actual piano tuning machine called Verituner http://www.verituner.com This has been made fairly accessible in its ability to tune a piano quickly and accurately and, i think, can give you a very accurate pitch readout. but you gotta really need one as I think it costs over fifteen hundred bucks.
The frequency readout on the talking meters isn't anything close enough to even get you within a half step of a pitch,it's probably 50 cycles plus or minus at a:440. there may well be computer software that will do the job, hope Jay williams knows of what's current and accessible. tom Fowle Net-Tamer V 1.13 Beta - Registered
