|Summary||0008777: LUFS normalisation for audio regions|
|Description||Right now the audio region normalization can be done based on Peak and Peak RMS measurements.|
What is missing is LUFS Integrated.
The only sensible way to perform LUFS normalization at this moment is to perform loudness analysis, write down the LUFS value, do math in your head and apply gain manually.
Since the Analysis dialog is blocking access to the rest of Ardour, this is extra tedious to do, especially if you need to normalize multiple regions (like for example: mastering an album and doing quick loudness normalization after importing your mixes to get in the ballpark before doing manual loudness matching.
Another way would be to import regions, then mark them all with ranges on the timeline and export them using loudness normalization, then import them again.
As you can imagine, neither of these solutions is optimal.
Since LUFS normalization is already present in the export process in Ardour, I hope it shouldn't be too hard to add in here as well.
What do you think?

When is this useful?
Can you think of any workflow that should encourage normalizing to perceived loudness when you later mix or master the the result, which significantly changes the perceived loudness?
||As I've written above - a rough level matching for album mastering is the main use-case for me but I believe I also needed this when working with sound effects, can't remember what it was though. Since EBU-R128 is the best perceived loudness model we have, it makes sense for me to use that instead of peak RMS which is in my mind an inferior solution for the same problem (unlike peak or true peak - these ensure no clipping).|

||Awesome, thank you! I will test it and give feedback.|
