I have a Xvid file which has 48000 Hz, 6 channels,AC3 DVM. I have installed AC3Filter ver 0.70b which is from soundforge site. The volume of the dialogues/speech is too low. but the other components like the surround etc are good. ANy suggestions/ideas ? I have tried playing withe filter settings but no good..
I have this problem too at times. You should look in AC3 Filter and enable the Normalization feature. You may have to configure it a bit, but it should work. If it doesn't, then you may have to just turn up the volume at those parts :).

Yes - this is a well-known issue with AC3 audio. From within AC3Filter, apply the 'loud' preset. This (on the newer AC3Filter) also enables Auto Gain control, which can make things too quiet again...
On a difficult (quiet) movie, full-loud, AutoGain disabled made all the difference for me - the audio was now audible! However, playing back StarWars3 (Sith) on this setting was tragic - too loud!! Horrible distortions of explosions... (too loud).
The auto-gain rolled the gain back just enough, the playback was excellent, although still louder than the base default.
In other words, just set the 'loud' preset and enjoy.
If still too quiet, disable the auto-gain, re-apply the loud preset and make sure both volume and gain are topped out. For a 'normal' movie ie. Sith, this may be too much though...
I'm afraid AC3Filter must be adjusted individually for each program you are playing back - otherwise, the loud preset with auto-gain is 'proper' but might be quiet still, when playing low-level source.
Hope this helps,
Regards
The_OGS makes a great point. All movies usually have different threshold's for sound, and a lot of changes to volume have to be made. I personally just use the AC3 filter found in MPC, but that's my preference.
Thanks for the response !!! I think the new AC3 Filter is better than the earlier release in terms in Clarity. But the issue of "low dialogues " still persist . Anyway as everyone has suggested , manually adjust the settings for indivisual movies.
May be this calls for some sort of standardisation in the AC3 encoding settings ...
Well, I'm pretty sure that the original DVD settings has it standardized, it's just the backing-up of the audio is what makes it seem off. More or less, just about everything is going to have a different volume based upon who originally encoded it and what is done to it after that.
I'm just saying that as long as you have something that sounds a lot better at the price of volume, it would just be easier to turn up the volume. Bye!
