Dumps SOS filter coefficients to file in C language format in forward order. Creates two files "filename.h" which defines the size of the array and declares the array as extern, and "filename.c" which contains the instance of the array variable. Only 5 terms are written per section, a0 is ignored. The output array order is {b0, b1, b2, -a1, -a2}.-Dumps SOS filter coefficients to file in C language format in forward order.　Creates two files　"filename.h" which defines the size of the array and declares the array as extern, and "filename.c" which contains the instance of the array variable.　Only 5 terms are written per section, a0 is ignored.　The output array order is {b0, b1, b2, -a1, -a2}.
