Ah, thank you - very illuminating (and reassuring) answers. You
certainly see meters around (in consumer hardware, as well as software)
that you just know are really nothing but eye-candy! ;)
The VU meter is I think another interesting example of the
cheap-and-easy in the analog domain being quite different from the
cheap-and-easy in digital. I've personally never used a hardware VU
meter in recording, so to me, DPMs seem like the traditional meter type,
and the averaging ones are the new-fangled ones. :)
As for meter refresh rates, I always appreciate a user setting for this
- though theoretically I guess you could do things like determining the
display hardware's refresh rate and varying the refresh rate depending
on reserve CPU capacity.
Thanks again,
Chris
