Rating Rating from Latest tool updates. DVDFab Can this process normalization , or what eac3to does, be done losslessly on the AC3? I hate VHS. I always did. Are you sure your AC3 audio is lower than normal? AC3 is normally recorded at about dB to leave room for big peaks explosions, thunder, gunshots, etc. All you usually have to do is turn up the gain on your AC3 decoder. Hi Jagabo. Yes, AC3 is recorded more "movie friendly" unlike MP3. The reason is that I have many different sources for TV captures, and many are music videos, and many that I've captured with NeroVision for a specific firewire tool are in a lower-than-normal AC3 volume IMO.

What I'd like to do is have all my content at a similar volume when feeding into a playlist. I can easily adjust the volume manually for each during playback to get a desired sound, but it's a bit of a pain. I was hoping there's a lossless way to do this for each file.

If you still think your dialogue sounds too quiet, the 2nd way to fix it is to choose the film standard DRC setting. It applies a much steeper curve to the range compression than film light does. The steepest of all curves is the 'speech' setting. Case in point: I have received a couple complaints from people who felt that the dialogue in my matrix edit was "too quiet. It is your call as the editor which setting to use. In truth you will probably have more people happy with your sound design if you choose film standard than film light.

Whether to please the masses or the snobs is the never-ending battle. What I may try to do as a compromise in the future if I have the room for an extra audio track is do a 5. The other settings on that preprocessing tab that I check for fanediting are 'DC-highpass filter', 'bandwidth low-pass filter', and '90 degree phase shift'.

LFE lowpass filter is really only useful if you are doing original audio mastering i. EDIT: None of these really matter in a fanedit. Now its my turn to ask a question! Does anyone know the scoop regarding the "set copyright bit" and "set as original copy" settings in the ac3 pro settings? I can understand now why I in my own set up I have the center and surround speaker outputs boosted by the decoder for when I watch movies. I did end up using db for my Return of the Sith release, but for my next one I might try during my testing to see if it makes a difference.

I mostly stuck with db since I figured the material was already properly normalized for this setting and that would be the safest path. Sorry I don't have an answer to your questions, though you might want to start a new thread since the topic of mine might prevent people from finding it and thus answering it! If there is a FAQ or sticky this info can be put into, I really think it should be done! Question for you -- if the center channel only contains dialog, can you analyze the center channel by itself to determine the N value, or do you need to analyze dialog within the context of all the channels downmixed to stereo?

Also, just to make sure I understand, by "normal dialog level" do you mean a scene where people are talking at "conversational" levels? Such as a conversation inside a room? Do you then try to determine what the average db is during that scene? Yes, "normal dialogue" was meant to imply conversational dialogue.

A scene where a married couple are arguing may not be where you want your center point to be. Mono, stereo, and 5. Brumous Well-known member Faneditor. Messages Reaction score 0 Trophy Points Thanks for seeking out the info, experimenting and reporting the results. The sound in my firstling edit would have been better if I'd known this stuff. For Mac users, I found the following free software called AudioLeak, which will give you both the unweighted and A-weighted RMS value of any size file.

The Dialogue Level setting represents the long-term A-weighted average level of dialogue within a presentation, Leq A. Click to expand Great links Seciors. It is interesting looking at the algorithm parameters for the DRC music presets. There is hardly any difference between these and film except that music light has a steeper attenuation on the levels close to the null range. Improve video files. Convert from. Convert to.
