What's the best way to make A-weighted measurements, or measurements using other weighting filters? I've plugged in a bunch of values to the FFT filter, which seems to work, but only at the sampling rate that I created the filter, and I'm not sure how accurate it is. Should I be using scientific filters, or is there a way to make the FFT filter the same no matter what you're using it on?
