We absolutely need visual metering that does LUFS but also more
and far better than a few widely spaced LED readouts
so we can meet local laws on sound levels in venues or locales as well as those
on AM/FM and the requirements of CDNs like utoob facebook itunes et al
It could be an add on that plugs into the mixer if AH does not think it popular enough for all to have it built in.
TC Electronics makes a very nice and complete metering unit; Clarity M. You can hook it up via the AES output of the SQ (among other ways) I love it 🙂
My Studio One DAW has wonderful LUFS metering in the project page. Most streaming is delayed a little bit for many reasons so processing a finished mastered two mix thru the DAW should present no streaming problem and there is a huge advantage in producing a high quality mastered recording at the same time.
