Default Re: HELP! Mixing for TV

Here's what everything means in English:

Quote:

a. The audio dynamic range of program material must be suitable for television broadcast. Guidelines: Instantaneous audio peaks shall not exceed +10dB over operating level, average peaks should not exceed +2dB, and average sustained dialog should not be less than -8dB.

Put a limiter (i.e. L1/L2/L3/Lwhatever) at -10. Don't let anything... I mean anything go over that

Your VU (hence "average") needle should never go above -18 Full Scale or +2 VU

During Dialog, your VU meter shouldn't dance anywhere below -28 Full Scale or -8 VU


Quote:

b. The minimum acceptable audio test signal shall be a steady 1000Hz tone. This tone shall represent the "0" reference level of the program material as read on a standard RMSVU meter or Peak VU meter.

Tone = 1k @ -20 (standard when you open up the Signal Generator in Pro Tools)
Your VU meter will point at 0

Quote:

Now, if I understand correctly I have to keep my average audio at 0VU (-20dB). My problem is when I actually do this(by Limiting/compressing), the VU meter only ocassionally hits 0VU. It just dances around pretty close most of the time. Is this correct? Or will my audio be rejected for having too low a level?

That is correct.

Quote:

Now. Just to clear everything up for me. According to the guidelines, my peaks shouldnt go over +2dB, would this mean -18dB in my case being my 0VU is set to -20dB?

Yes.

What network is this for?
