XML file session : convert natural db value in calf gain value

[lynerlok]

Hello,

I want to generate level value for EQ 12-band from a text file generated by an audio analyzer and processing software. So I have freq, gain and q from this file and I want to put in xml calf session. I searched in code but it's pretty difficult to find where values are processing. I want to notice that I am developper so I understand technical terms easly.

Please, how can I transform the natural gain in db of the text file to the scale of the "calf session xml file" ( float number ) ?

I found all equations and utils of biquad filter in loudness.h and biquad.h and all the GUI stuff in some files, but not the place where XML session is loaded and processed ( expect in GTK headers ). So I think I miss a puzzle piece.

Have a nice day
