Dialnorm… Help!

[Tom Brooks]

Kyle,
This is a topic on which many of us are relatively stupid. A few who have worked out the details know what’s up. That isn’t me, but the way I understand it is you have to deliver a mixed track in which:

1. The dialog-only yields a -23 measured value for LAeq
2. The other effects and music are mixed with dialog to your taste
3. The peak levels of the entire track are within specs

This suggests a workflow. First get the levels of your dialog right. Measure with the free Channel-D tool. Go back and adjust till it measures correctly at -23. Then adjust your mix to that. Then check peak levels throughout. Deliver in the format of your choice. Admittedly, there are most likely some hidden complications.
Comments anyone?

Yes,that’s the way to do it.
He still needs to find out whether he needs to deliver a muxed file (program or transport),
or seperate video and audiotracks.

Just want to point out that some networks require that you adhere to other specific settings as well as dialnorm.
These could include settings for any or all of the following:

Bitstream Mode
Channel Mode
LFE Channel
Line Mode Profile
RF Mode Profile
RF overmodulation Protection
Copyright
Original Bitstream
Dolby Surround EX mode
DC Filter
Lowpass Filter
LFE Lowpass Filter
Surround 3 db Attenuation
Surround Phase Shift
and other downmix settings relating to surround mixes.

Well, the spots are uploading right now. I’ll just keep my fingers crossed that I did everything right and they make it through QC.

Thanks to everyone who chimed in!

[James Reid]

Good. Please let us know how it all pans out.

Although for post work, AudioLeak is a useful (and free app) to determine dialnorm
when dealing with a recorded seperate dialog track, for live broadcasting and professional use the Dolby LM100 is The tool.
If you like shiny things and have a spare $3,200 and plan on doing a lot of Dolby Digital ptoduction in-house, by all mean get one.
The LM100 employs Dialogue Intelligence

Was wondering if anybody could clear up some questions I had about dialnorm. I have read the thread and been reading up on it online but am still a bit confused. I am preparing a music video for braodcast submission to a music video channel that specifies that dialnorm be set to -24. There is a part during the video where there is dialogue, and it is ADR which I have edited in protools. This is just 40 secnds of dialogue. If i was to export the dialogue audio track track to check the LAeq in AudioLeak, would I just export a section of the audio to get the weighted average or would I export the whole duration of the track, even though that would bring down the LAeq.

How would this be done if I was doing this for a movie? Would it be the whole dialogue track or just a sample of it, because there may be sections during which there is nothing on the dialogue track but that would bring down the LAeq.

Also what would one do it they had location sound which would include some folley or background noise? How could they get a proper dialnorm so as not to be rejected by a broadcaster?

I appreciate any help anyone may be able to offer. Please let me know if you know any of the answers to the questions.

Thanks,

Tom

Hi Jeremy,

You said that it’s possible to export a multiplex mpeg2 with ac3 audio in Compressor. This is exactly what I’m trying to do but I can’t find a way.

Could you let me know?
