Export Wav file calibration

[Bruce Yao <bruce.yao@xxxxxxxxxxx>]

Dear all,

I have recently downloaded the loudness toolbox from Genesis because  
of its capability of measuring N10 loudness from a wav file.
Our lab has a basic ArtemiS software that can record loudness level  
but not N10 loudness. I was able to export a pure 94dB tone  
(calibrated at 94dB) to wav and open it with the loudness toolbox.  
But, the pressure(Pa) shown in MATLAB is not comparable to what I have  
in ArtemiS.
After a few days of trial and error I found out that loudness toolbox  
in MATLAB read the wav file with a pre-set 85dB calibration factor.  
Since I can not scaled down the 94dB file to 85dB because of  
overmodulation, is there a way for MATLAB to import the wav file with  
94dB calibration?

Thanks in advance!
Best Regards,
Bruce
