| The LM100 only does Leq(A) and ITU-BS.1770 so if that's what it's going to be measured on he should look at the plugins I suggested. The 737 (Leq(m)) doesn't help (that's quite a different weighting curve.)
I do agree that the positive numbers vs neg numbers confused me from the OP. I'm the wild guess of 82 = -23 based on SMPTE = 85dbC = -20dbFs |
