Hi everybody,

 

i have a question about the export files. I want to recalculate the parameters Frequenc1, Boost, Gain1, Ripple etc. of 2nd Order Filters by using the coefficients b0, b1, b2, a1 and a2, which are saved in the * .params file after i export the files. To make this recalculation i need to know which filter type (Peaking Filter, Tone High Shelf,.....) was set is SigmaStudio. It is possible to detect this filter type in the export files?

 

Example: One Peaking Filter

 

Design 1.params:

 

Cell Name         = Param EQ1
Parameter Name    = PEQ1Chan10B1
Parameter Address = 0
Parameter Value   = 1.00168943405151
Parameter Data :
0x00 , 0x80 , 0x37 , 0x5C ,

 

Cell Name         = Param EQ1
Parameter Name    = PEQ1Chan11B1
Parameter Address = 1
Parameter Value   = -1.99559164047241
Parameter Data :
0x0F , 0x00 , 0x90 , 0x74 ,

 

Cell Name         = Param EQ1
Parameter Name    = PEQ1Chan12B1
Parameter Address = 2
Parameter Value   = 0.993968844413757
Parameter Data :
0x00 , 0x7F , 0x3A , 0x5F ,

 

Cell Name         = Param EQ1
Parameter Name    = PEQ1Chan11A1
Parameter Address = 3
Parameter Value   = 1.99559164047241
Parameter Data :
0x00 , 0xFF , 0x6F , 0x8C ,

 

Cell Name         = Param EQ1
Parameter Name    = PEQ1Chan12A1
Parameter Address = 4
Parameter Value   = -0.995658397674561
Parameter Data :
0x0F , 0x80 , 0x8E , 0x44 ,
