I have been trying to import an impulse measurement into FIR Designer M, but the frequency and phase responses appear inaccurate. With the original impulse the response is smooth with no ripples (as can be seen when imported into Room EQ Wizard), however when loaded directly into FIR Designer M the response is altered and slight ripples appear sub 500hz in both the frequency and phase responses. While trying to figure out the problem, I did observe that the impulse seems to start abruptly (almost as if it was cut off in the beginning). I assume that this is the issue because all other measurements that did not have this feature were smooth, but I have yet to figure out a solution. Any help would be appreciated.
