At 5000 taps I'm getting ripple and a greatly reduced slope for the low pass starting around -100. The default 8192 taps shows a textbook roll-off and a nice continued slope as far down as the graph will go. I've got a 35hz hi-pass (250 low pass), so right away I understand that's going to require more than a hi-pass at 80 would. I'm playing around with different numbers of taps in rePhase, and I'm wondering what the threshold for quality is (I suppose that's subjective). I don't know anything about how these FIR filters are built so this is a learning experience. I've set a second zone for now with min phase filters to use the loopback, but I'm going to look into the number of taps for the filters. J River says they're working on convolution latency handling for the loopback function. The eq in rePhase is a bit buggy as well, at least in the Gain Bank. The A + B trick gets kind of close to the actual result, but gets tiresome when you're working with 20+ filters. The same set of filters plugged into rePHase's eq don't produce anywhere near the same result.
Measurements confirm that REW's simulated eq'd response follows the actual output fairly close. Typically I build my eq filters in REW and copy them to the parametric eq in J River.
