I don't know if I really understood the meaning of your question, but
here is what I can tell:
- most of the functions in the toolbox need a Matlab vector as input,
corresponding to a signal in Pascal (in order to not be limited to a
particular file format and calibration issues). It means that
calibration should have been done before the call to the function, if
it comes from a Wav file the user should know it,
- concerning the WAV files provided as examples in the toolbox, they
have a calibration factor of 1, meaning that wav data are directly in Pa.
If you run the Loudness_Validation.m function, it will compute of your
PC the figures and plots provided in the file
Hope I answered to some of your questions.

I agree with Brian: this is a great tool!
A perhaps naive question: is there an easy procedure for calibrating
the toolbox (at the end, a wav file contains no information about
I guess one could do something based on the example wavs, but perhaps
your feedback might save me/us some hacking time.
