I've just been through a calibration process for several of my systems, and=
A-weighting does matter. One must measure the recorded tracks with A-weigh=
ting. Pro Tools has an A-weighted meter in the PAZ meters supplied with the=
software, but they are difficult to read and require a correction factor (=
they measure combined stereo level -6 dB. Spectrafoo doesn't have A-weighti=
ng. My best bet so far is a set of parameters for three equalizer plug-ins =
in series to create A-weighting, the result measured with Spectrafoo. That =
requires a level adjustment to calibrate to unity gain at 1K, but it can be=
recorded in the setting of one of the equalizers.
There's also an interesting "true peak" meter in Pro Tools 8 but I'm remote=
right now and can't remember its name.
