LUFS Metering and Panning Law
So I think I figured out my problem, but would like some input.
I just started dabbling with LUFS metering, using Youlean Loudeness Meter 2. Came upon what I thought was a glitch, but got the same results with dpmeter2. So here it is ...
I mixed a song to LUFS -14 integrated with short-term max of 0.0. Cool. However, when I play it back it has a perceived loudness clearly 4-5 dB lower than other songs I've mixed to LUFS -14 integrated.
Loaded my mp3 into Youlean's online loudness meter to test, and indeed, it is LUFS -18 integrated.
Turns out that what I believe to be the problem is my panning law, which on THIS project was set to -4.5. So Youlean and dpmeter2 appear to be thrown off by the panning law adjustment: the metering in REAPER (with both plugins) shows a LUFS of -14, uninfluenced by the panning law; the output mp3 shows the LUFS after the panning law cut is applied.
So I modified the panning law to boost the pans instead of cut the center by 4 dB, and now the output file shows the same LUFS -14 as the meters in REAPER.
Is this a glitch? Both dpmeter2 and Youlean show the same readings. Am I seeing things properly?
I "think" I should be okay with the adjustment above. Thoughts?
