VU has its own well defined ballistics that take into account the moving mass, and therefore momentum, of the needle, as well as the magnetic damping that occurs as the armature coil regenerates the opposing current as it moves in the magnetic field of the poles, etc. etc. > so there is no > real correspondence to dBFS. In fact, VU is an arbitrary "reference standard" that correlates to nothing at all, except as a reference standard. Kinda sorta like zero degrees F. It's not where water freezes, nor boils, nor anything except as an apples to apples comparison to another F thermometer. > It seems to me that peak normalization of -13 doesn't make sense, > because it is just throwing away 13 db of level with no real benefit. You can think that, but when you consider that in the "old days" zero on the console was still 22 db ( more or less ) below the rails, in fact normalizing to -13 has already "gained" +9 db !! > There is a real loss when playing on a cheap sound card that has > output level too low to begin with, and maybe also has a noise level > higher than it should be. In which case why would you be trying to use a professional play-out system by and for professionals on amateur junk ? Two cans and a string also has low levels and high noise ( depending on the wind at the moment ) but I'm not sure it has anything to do with professional environment audio levels ? -- Cowboy _______________________________________________ Rivendell-dev mailing list [email protected] http://caspian.paravelsystems.com/mailman/listinfo/rivendell-dev
