Dolby Sourround Sound Dialog-Normalisierung?

Dolby Surround Sound dialog normalization?



Frage von jwd96:
September 2010

Today I worked even a little movie in Soundtrack Pro, and then as 5.1 Surround Sound. Exported ac3 file for DVD.
However, I was not sure what to adjust in the "dialog normalization"?
The default was -27 dBFS, but is it synonymous rightly so, and what does that mean anyway?
Is the sound on the DVD s.end then down?



Antwort von Marco:

Yes, the loudness is thereby reduced. I still do not know what to think of the dialogue normalization. I assume this is why the value of -31 dB and disable the related Dynamics compressors. Then the sound is still about the loudness exactly as it was synonymous with the mix.
My experience are based on the AC3 Encoding with Vegas Pro.

Antwort von MK:

The correct value can be, for example, with the Dolby Media Meter determine. Is actually meant that dialogues and thus synonymous to the rest of the program at any of Dolby system to play the same volume.

Without properly identified Dialnorm value should be synonymous for all metadata from the compression, since this can lead to unwanted side effects such as pumps.

In the Level-31dB Dialnorm during playback of Dolby streams is theoretically just as loud as the original source data.





Antwort von Axel:

Lack of own experience, I do not know what specifically is raised or lowered, but diec "Dialog Normalization" refers solely to a stereo downmix (eg through the issue of L, R RCA). Then enter the dialogues (the channel C), so they do not perish in the effects, the DD decoder raised by (or the other channels just lowered, completely ignored low-frequency effects). About a surround sound system the sound is just as it was mixed.



Antwort von MK:

The Dialnorm metadata apply to both 5.1 and 2.0 = synonymous for dialogue intelligibility on all systems the same. White Paper with infos for download at Dolby.
