Peak loudness export setting in Lufs

Your idea

For production purposes, it would be nice to have an option to set the loudness of the exported product, to a specified peak loudness measured in Lufs.

If the peak loudness is for example set to -7 Lufs, than there should be no moment which is louder in the audio file. The loudness of the whole piece of music should then be adjusted accordingly, not just the peak loudness lowered or increased. The loudness relative to the loudness of the other parts of the music, should stay the same.

Problem to be solved

For production purposes, you need to have the peak loudness of the piece of music in mind.
If the peak loudness is over the set loudness in Lufs on a given platform, they normalise it under loss of audio quality.
Doing it manualy after, isn't a big problem, but more work.

Additional context

No response

The issue names no files, tests, or entry points. Start by locating the audio export path and confirming the intended LUFS measurement and normalization behavior with maintainers; done means an export setting applies the requested peak loudness while preserving relative loudness across the piece.
