Hi all!
I have a problem with LUFS levels that change when I export my projects. I've got a finished mix, have analyzed the LUFS values with Youlean Loudness Meter, then exported the project as a wav-file. Next thing I've done is to import the wav-file into a new project in order to master it. This is where the fun starts. I run the Youlean Loudness Meter again and expect to get the same results as I got before I exported the mix, but no. Not by a bit. The Loudness range increased by 3 LUFS and the integrated LUFS increased with about 2 LUFS (making it louder I mean).
So since I didn't know what was going on, I checked other projects as well and out of 7 different projects all had changed somewhat. Some contained only minor changes, but others more severe, like getting 6 LUFS quieter (!) or LU loudness range changes by 5 LUFS, (although these were not in the same project). I mean, it gets a bit unpredictable to work with when it behaves so irradical
So I wonder what this can be? I read a thread about normalization on this forum, but I haven't touched any normalization button (don't even know where to find it). I just record my music with virtual instruments, try to gain stage as best I can and get the mix in the ballpark before exporting it for mastering in a new project file. But it does sound like something's going on under the hood, and I don't know what...
If anyone has any advice or theories about what this can be that would be highly appreciated!
