I have looked everywhere online and no one explains it fully.
I beg of you to please explain it clearly - not what is normalize in general, but simply what should I choose when I click on Normalize in the Audio Edit of TMPGEnc?
All I know is that Normalize must be between 0%-100% with a default of 75%. So let me ask more directly:
1) What should I choose in Normalize if my initial volume is too low?
2) What should I choose in Normalize if my initial volume is too high?
You didn't look very hard. Within the last 5 days there has been a serious post answering your exact question on this forum. The title had to do with loudness. I just looked it up since you couldn't find anything on the topic after extensive searching. It is about boosting volume. It had been answered the day before you posted this.
You speak like someone here would actually know what TMPGEnc is and maybe you are correct. Is this for a video? I would not use TMPGEnc for a audio file, maybe for a vidio file. I try to keep current on all the good audio apps but not video editors. Maybe it is a fine app but I suspect it is junk. I never heard of an app the does precentages of "good". The problem with that is it is down right WRONG!!!!!!! There is no absolute good level.
I would pick a leader mentioned in that post. 2 were mentioned both concidered the best normalizers out there. Maybe if you try a good one you might be less confused. I would stear clear of junk if I were you.
Serious apps do not approch normalization that way. YOU pick a target loudness. Usually something close to 90 dbs is preferred. Sometimes that needs to be lowered to prevent clipping.
Sorry for the additude but you came off as someone of intellegence that did their homework. I do not think either are very accurate. You are far better just saying that you don't know anything. I might have even tried to give you a dummed down explaination of normalization.
Where does all this rage come from? Why would you take a purely technical question and start to curse the poster?
Regarding your comment on my intelligence, I suggest you learn to spell the word. But if you didn't mean to sound so rude, then I'll tell you it's indeed for a video, which is why my question was about video encoders. Since you didn't specify any link, I've looked again and found nothing in the last couple of days about normalization in video encoders or normalization by percent.
I haven't said once I know about normalization. As a matter of fact, I even stressed I don't...("All I know is that Normalize (I meant in TMPGEnc) must be between...").
I just wondered how it works in TMPGEnc. Actually, it's the same in DGMPGDec and probably in other video encoders as well. I never imagined it would make you want you to hurt me and probably also any video encoder's author who dared to offer internal normalization by percent.
Sorry! I didn't curse but I gave you more attitude than you deserved.
I think the reason you can?t figure it out is because it does not much sense. What I use to normalize, analyses the audio before you do anything so you can make an informed plan of action. Normal is usually 89.? But I can?t even guess what the other part of the ratio they use to make the percentage. I assume they pulled it out of their ass. Some music will clip at 89.0 so you need to reduce the loudness. As for what they are doing with their percentages your guess is as good as mine. I guess the software planners did not want to scare you with decibel numbers so they gave you meaningless percentages.
Let's just settle this as "How do I use the Audio Normalize Filter in TMPGEnc Author Works 4?"
Just because someone sees the word "normalize", it must mean some statistical function and go ranting as something unrelated to TMPGEnc.
The normalize filter works like most simple audio normalization algorithms. My general rule of thumb, not more than 95%. Personally, I use 97% (as recommended by Cool-Edit a long time ago) for two channel tracks and much lower if I'm going for 5.1 channels. Frankly, I prefer to normalize my 6 channels outside of TAW4 and only use this for 2 channel audio.
As a general rule-of-thumb, all audio tracks normalized to the same percentage should have the same "loudness". It is a statistical function after all... an attempt to standardize the volume of all audio tracks in a DVD compilation.
Lastly, the proof is in your hearing. You do not want the normalized audio to clip in areas when the source is fine. Also, you want all clips in this DVD compilation to have the same loudness, not having to increase/decrease volume as you jump chapters/tracks. You should use this filter just for this purpose, and nothing more elaborate. It's a quick-and-dirty filter.
I would only normalize 2 channel audio tracks to match any 5.1 audio in the compilation and not vice-versa.
Perhaps we can now have some peace in this thread?
XEQ.
