Re: (MOVED) - FIR discussion spinoffVery true and well noted Arthur. The modeling and related math legwork that goes into this is the part that is beyond the means of the average person at this point in time. Determining and accounting for the stuff that is "linear time invariant" is the goal, but a measurement mic is not really the weapon of choice here. Nevertheless, just creating brickwall crossover filters along the lines of the lake processors is of benefit in some circumstances, and this is achievable in DIY FIR with a little effort. You could make "flat phase" presets using FIR brickwall filters and traditional allpass filters that might not be in the same league as a FIR preset by companies like Fulcrum, but they would certainly have potential for high quality and very affordable processing for a user with the right know-how.
