DSP and Plugin Development • Quest for perfect resampler FIR filter how does it work? 64X12 64X24

so there is an 81 coefficient halfband interpolator you are suppose to decimate and apply this 81 coefficient halfband fir for mip mapping purposes

but i dont quite understand the 64X12 and 64X24 fir interpolators what stage they are used

and do i just perform straight forward convolution with them with worrying about which mipmap they apply to?

64X24 if for upsampling by 4/3 i think in the paper.

Code:

double fir_halfband_lpf [81]double fir_interpolator_1 [64 * 12]  = {,,,,}double fir_interpolator_2 [64 * 24]  = {,,,,}
