(that LUFS value in Preset 1 is just an arbitrary artificially high value I chose to cover nearly all super loud possibilities of the original clips. It could be set to 0 LUFS or +3 LUFS or +6 LUFS, doesn’t matter. Technically I guess it should be set to the highest value the program allows, but I didn’t want to do that if someone could accidentally play super loud gains like that in the middle of a multistep process. A mutistep process that eventually reduces those gains for normal playback.)
EDIT: Something gets weird if all clips are targeted higher than about +10 LUFS in Wavelab 8, then attempted to match a normal level clip. The loudness matches are not correct to the normal level clip. Maybe that’s why the LUFS levels are limited to a maximum of 0 LUFS in Wavelab 9, so it’s probably a good idea to use a maximum of 0 LUFS in Wavelab 8 when doing this. That should cover anything anyway I think.
