I'm mastering a project right now, and shooting for -14 LUFS with -1dB TP. I have Pro-L 2 set with a -1 dB ceiling and my integrated LUFS meter in Pro-L 2 reads as -14 when I play the whole song. BUT when I export the track and then bring it back into reaper, if i bounce it a second time from reaper (without any plugins or volume adjustments, should be the same exact track) the reaper analysis tells me that the peaks are at -0.1 instead of -1, and the LUFS reading is -13.
Any ideas what is causing this discrepancy? Trying to be accurate for my client and not quite sure which figure to trust.
