Re: [Avid-L2] Full Mix vs. Full Mix-Web?

That article was very interesting.  I think I've had a misunderstanding about Calm and Dialogue Norm.  When it all came out and Discovery Channel started rejecting tons of shows that had proven workflow track records I remember attending a meeting to get things straightened out.  I have been under the impression that the LM100 box from Dolby was able to discern what was dialogue in the audio signal and that's what was being represented for the dialogue norm reading.  This article describes the loudness measurement as the overall perceived loudness without an isolation of what is dialogue in a signal.  So did the LM100 actually isolate dialogue in it's measurements or was it just measuring perceived loudness of the overall signal?

The Calm act was explained to me as a way to make dialogue match across different content as one channel surfs and the different dialogue norm specs were to allow for more headroom over the dialogue.  IIRC Dial Norm -20 was news, -24 for most content and -27 for Action Movies etc...  Later they simplified to making everything -24.  I'm not sure where it all stands today so don't trust the figures I just mentioned to be accurate.  Can someone clarify this more?
