I ve and dvd and going to re-encode to xvid avi format
I ripped out the 5.1 ac3 audio track. However sound effects are much louder than the center vocal sound , how do I fix it ?

again you can try eac3to and use the "remove dialog normalization" function.

Hi!

You can use any audio editor to simply raise the midrange...

how to do it directly on the ac3 track with a format conversion (ac3->demux & encode to wavs -> raise center volume -> mux wavs and encode to ac3) ?

Avisynth script:

audio = NicAC3Source("C:\...\AudioFile.ac3")

FL = GetChannel(audio, 1)
FR = GetChannel(audio, 2)
C = GetChannel(audio, 3)
LFE = GetChannel(audio, 4)
SL = GetChannel(audio, 5)
SR = GetChannel(audio, 6)

C = AmplifydB(C, x)

audio = MergeChannels(FL, FR, C, LFE, SL, SR)

SoundOut(audio)

where x is an integer (amplification in db's)

.. dll's within avisynth "plugin" folder. Open this .avs text file with virtualdub.

It's very strange central channel needs edition in a commercial dvd, though

No, Dialnorm is applied to all channels.

Thanks! Didn't know that! ;)

Are you sure? I think only on center channel. DRC is applied on all channels.

Both, DialNorm and DRC are applied on all channels.

Edit: I agree with Susana also with the avs method (I was writting the same thing for BeHappy when I see the Susana post), and with the comment:

I think is a player problem not in the source, but ...
