[QUOTE="Bennett Prescott, post: 23359, member: 4"] Re: DSP Tower of Babel David, The issue is just one of making the data palatable. There are processors that hav different filter shape depending on sample rate, shape that changes with frequency, severe math errors at Nyquist, and math errors with certain configurations of filter type. One processor, at least, changes the definition of the Bessel filter depending on its slope. To characterize every processor to this level of detail would require more space than I have in the magazine, and not necessarily serve the primary point of the article which is "all processors are different". I think "some processors are really fucked up in the head" would be a whole separate article. I would certainly need to take the measurements for that article myself, since they would require a much more significant time investment. I am very fortunate to have this community to draw from in order to get the measurements I have, which certainly illustrate the point of the article. [/QUOTE]
