Infoseite // Soundtrack Pro, final mix standards -9 db, etc. Why?



Frage von Randoms:


I just sit s.meinem first sound mix and wonder why one for broadcast and DVD, the -6 dB as the peak will not exceed.
Clipping still occurs only over 0db.

If I could go through the master control and peak display is sure that will not peak over 0db, then why give runterregeln and Dynamics?
Can someone just explain to me?

The second question:
Mix in Dolby Digital 5.1.
Does the AC3 codec in the render, so of Aiff to AC3 conversion so that the DVD he Dynamics somehow created yourself, in which he governs Language Effect sounds quieter than intended reinknallen then?
Again, I add me again conclusively the question of how runterregeln to -9 or even-32db, if the clipping until s.0db begins.

-9 RMS or more (, -10 dbFS + / -1) is
Peak is -1

You see, on DVD with the value of the already generous. But it always comes to the integration time of the display in ... it is a significant difference whether you choose 1 ms or 10 ms.
There are at PCM (incidentally, no clipping, as in the analog domain, in which only increases the simple THD) ... The clip begins as a non-db at 0! .. the CT respond differently (; bitchy).
This can be a sound synonymous .. (; as we all know from the error-correction).
Incidentally, it is for the "Fernsehbegleitton" pretty irrelevant, is at 96 db Dynamics where the reference level, as long as somewhere in the upper range and not just over the last significant bit.
But it's so synonymous that operate the transducers in the upper region, ie at -6 to -10, and the best sound in some cases noticeably better than s.end.
But einwenig depends on whether you have 16-bit or 24 bit converters. With 16 bit you should put the level even higher einwenig.
Incidentally, there are surveys that the time spent on TV channels with a loud sound levels (, or excessively large dynamics) is significantly lower than on TV channels to keep themselves s.den specified level. The synonymous applies to advertising in which the different audio levels up. Viewers would rather switch to another channel, as disruptive volume change ...
Volume may therefore be counterproductive synonymous ..
So ... no reason for the last dbs tickle out to ... quite the contrary.
The issue with 5.1 I did not understand, but is an encoding AC3, AIFF dahingegen a format ... So something gets mixed up there.

Hi Wowu.

I have now but synonymous found in an Apple Book.
(For music productions; Ex CD) is so mixed:
Peak: 0db
RMS:-6db

For TV:
Peak:-6db
RMS:-12db

For DVD for TV / Projector
Peak:-6db
RMS:-12db

When sound movies
Peak:-6db
RMS:-31dB

Especially for movies and DVD AC3 higher dynamics is important. As I have understood this, the DIALOG placed on the RMS value of db, so if it's right rumms upwards "place" within the meaning of db headroom remains.

@ Randoms

Whether this is because Apple's book correctly, I do not know, does not correspond to -12 RMS for the broadcast standard and would be a too low level ... Peak and -6 as well. would reject you of a technical inspection as "unterpegelig.
It is synonymous with the great dynamics as a cause. About 90% of currently available in the market tv sets come with a speaker, the 12 cm (; or smaller).
If you pull up so you need to type your dialogue, because it was recorded too low, then you fly in a "rum", the membrane s.den mechanical stop .. whether that is the point?
In movies and in video projectors, can be connected with sound system, I understand all that still.
You have to pay attention to the mix than in Zeilwiedergabe.
Therefore, TV is often synonymous mixtures of different (Cinema mixtures or the TV stations make everything before the broadcast by an air compressor to run) ... Then you have difficulty, however, is synonymous Dynamics rethought out ...
My recommendation is based s.den listening habits of the target persons and which is still among the most TV.
And -12 would be me then too little and would leave the tips I did not end at -6 synonymous ... synonymous because I would take the amount already. Especially since you have to do so with a final mix on and (no acoustic surprises as in the recording - or life) more of you to come.

Antwort von Randoms:

I see it as you, so I understand this is not synonymous peak 6db "standard". In the overall dynamics indeed lack the db up to 0db line. And as you already say, yes, there are no surprises in the mix.

What is exactly is the difference between the statements:
db
dBFS
dbFu

?

Antwort von WoWu:

db is the basic unit of measurement is logarithmic (and here for the Comparison of level or volume) ... hence the doubling of performance with an increase of (; approximately) 3 db.
The trailing symbols denote the relation:
Also: Reference dbV = 1V; respect dbW = 1 watt = dbA with A weighted sound pressure level, etc.
dbFS stands for the evaluation "Full Scale", which is 10 dB below Full Scale.
What dbFu mean, I know, unfortunately, not synonymous?
In what context did it say that? Maybe this is just the same as synonymous FS, except that only "full"? :-))
