I have noticed an anomaly with the Dirac delays that I can't explain. Recall that with the bass management plug-in, we can now observe the trims and delays that Dirac is calculating. Here is what I observed:
Trims and delays for the "Auto Targets"
Trims and delays for the same project
, using custom targets
Note that in the Auto Targets screen shot, the right front speaker is the "reference speaker", with delay set to zero. The other delays are offsets from the reference speaker, with the left and center speakers showing very small delays, which coincides with the physical placement of the LCR speakers, all 9ft from the MLP.
Now look at the custom targets screen shot. The "reference speaker" has now shifted to the sub, which is 13ft from the MLP. Once again, the delays for the LCR speakers are almost identical, with 3.96-4.06ms delays corresponding to ~4.5ft of delay, which is reasonably close to 13.1ft - 9ft. So far, so good.
But what is strange is why Dirac switched from one reference speaker to another, i.e. if the sub is indeed the furthest speaker, why is it not the reference speaker for the Auto Targets? And why are the trims and delays identical, whether Auto Target or custom target, if it is the same project? And does all of this make any difference? I can't come up with a good explanation.
, is this worth asking MiniDSP support?
