Yes. I understand the low frequency filtering - and the hpf come to that.
My question was around why the compensated response was not flat at very low frequencies (measuring 2Hz - 24kHz @ fs 48kHz).
John's advice on IR window size seems to have sorted it. Still a few things to check as had some...
Hi. First of all - thanks for REW. Just getting into using it seriously for hobby purchases (although quite a bit of experience with Audio Test kit eg AP2/Neutrik A2 longer ago than I wish to think about !)
So - I'm taking a Cal reading of my I/O for a baseline. I think I'm doing that correctly...
