But it makes no sense to use dbV or dbSPL for a digital system unless
you have a well defined mapping from 0dBFS to a reference voltage and/or
sound pressure level.

What I learned is that recording engineers have the mappings from 0 dbFS
to dbV for certain microphone and preamp configurations.

I am still seeking more information on my Matlab aviobj question because I
had already tried what was suggested.  But I don't understand the
relationship between hold on and hold off and adding frames to avi
objects.  With respect to saving each frame, I am not sure of the exact
procedure for that.  I would also like to understand what memory
requirements and issues exist.  The computer at work is recent but the
computers at home are not.

Huh? I had a moderate quality cassette recorder in the 70s which had 
better normally measured properties than that...

I am saying that the mastered dynamic range is such, not the dynamic
range of the gear. The range from the soft parts to the loud parts,
not from the noise floor the clipping ceiling.
