Default Audio Specs for Television Broadcast

Hi all,

Here's what we got from the WB last year. The notes on audio levels read as follows:

"The audio dynamic range of program material must be suitable for television broadcast. Instantaneous audio peaks must not exceed +14db, average peaks should not exceed +2db, and average dialog should not be less than -8db".

If -20 = 0, do we all understand this as
*-6 = instantaneous audio peaks
*-18 = average peaks
*-20 = 0
*-28 = lowest dialogue?

The QC guys at the dub house got us into the habit of never exceeding -10.

1) Have the QC guys already seen the audio spec sheet from the various networks?

2) What about spots/promos... do certain mixes get as hot as -4 to -6. Do those commercials get QC'd?

3) Any differance in delivering Surround vs Stereo mixes?

BTW, here's how Fox's reads:
"Relative to test level (nominal -20dbFS), instantaneous audio peaks must not exceed 2dbFS, average peaks should not exceed -4dbFS, and average dialogue should not be less than 10dbFS".

These where given to us for 1/2 hour format TV series that we do. Comments on this topic by all, I'm sure would be helpful for all.


Thanks
