Oh, good, it's you, N-set.  This is a COOL idea!  Maybe you can set me straight.

The way I see it, to be significant, the full-spectrum sound recording alone would pose its own challenges, for sure.  And what are the parameters for linear measuring, and storing measurements, and for extrapolating the data?  I wonder what it would take in terms of procedure and equipment in order to wind up with "accurate" measurements in the first place, and then again after a carrier had been added and "removed".  Looking at a square wave "post carrier", the top band is typically wide and fuzzy with residual carrier frequency, which I see (and hear) as "smeared".  Yeah, NASA gets around this; but not the average audio "lab".  Am I just "seeing" this wrong (as I am wont to do)?

Best regards,
Paul
