| REW misses a peak???
Last night when running my new REW setup (v4, MobilePre soundcard, and ECM8k mic), I found an interesting problem.
I did the usual measurements and eventually tried to apply filters. I should save the image and post it here, but suffice to say, I only had about five peaks in the 20 to 200 Hz range. One was big at around 60 Hz, the rest were pretty small except one around 80 Hz.
Here's the thing: REW didn't seem to see the hump at 80Hz, even though it was considerably bigger than all but one other peak. It suggested filters, I applied them, and it flattened out a lot, but there was that 80 Hz hump.
Couple of things:
This hump was in the middle of the crossover rolloff, so peak is relative to that . . . however,
All but the 60Hz peak were on that rolloff section as well
I just found it odd that it didn't see that one, but picked out smaller ones to flatten.
Anyone else seen this behavior? Other than a manual filter there, is there any fix or way for it force or "re-examine" the peaks?
Just curious,
A
