Increasing sound of ripped movie??

[Rommyke]

Hello

Is het possible to increase the sound of a ripped movie , and which program do I use ??

Hope for an answer

If you have the matrix mixer filter installed, then it's as simple as raising the gain in the configuration. You can also raise the gain for the voices and that makes the movie sound better overall.

Hello Hiro2k ,

no I don't have the the matrix filter, but I want to increase the sound permanently and burn a cd so I have a propper sound on my stand alone player

thanks for the anwser

Practically any audio editor will let you change the gain. You'll need to demux first, change aud, and mux back.
.
I use EXPstudio's audio editor.(cost)

tnx mudda_t

I use aukoGK to encode the movie and I don't have to do anything ,

So by demux you mean get the sound out of the movie with virtualdub and change the mp3 sound into wav and then change the gain and mux it back ??

This is new to me so I can be very wrong ?

hope you can tell me more

So by demux you mean get the sound out of the movie with virtualdub and change the mp3 sound into wav and then change the gain and mux it back ??
demux= demultiplex= splitting to audio and video.
mux= multiplex= joining audio and video.
.
I'm not familiar with virtualdub, but yes "get the sound out of the movie". If you do use an audio editor it'll convert your mp3 to wav automatically to edit, no need for you to do it. I would suggest you try TMPGEnc to demux and mux with. It'll give you an mp2 file instead of an mp3, which is what the audio really is. TMPGEnc is covered all over the site, it also has it's own thread.

oké mudda_t , I try it out thx

Hi-

You didn't say what kind of audio. If it's AC3, then it hasn't been touched by GKnot. It's exactly the same as on the DVD, and will play fine on your standalone. If it sounds soft when playing on the computer, just adjust the settings in the AC3 filter.

If it's MP3 you mean, then you can raise the volume using MP3 Gain (http://mp3gain.sourceforge.net/). Be careful, though. If you raise it too much, then you'll get clipping (distortion) during the loud parts.

I also have noticed that I have to turn the volume up on my Backups sometimes. While usually not a problem, it would be interesting to find out why. I have observed that the audio gain seems to drop about 10% using DVD shrink but does not decrease when the DVD is split using IfoEdit or DVD Fab, copied in ISO mode, or compressing using the big three. I don't want to point fingers, particularly because I love DVD Shrink, all the evidence seems to show that DVD Shrink somehow does reduce the volume of the backups, although I have no idea how because DVD Shrink doesn't do anything with the audio but copy it. I think I'm more confused now than when i started this post?

hi Manono ,

I tried it out and the sound is perfect with mp3gain ,

I did also a suggestion in the development forum from autogGK to build in mp3gain to autogk as a step before it muxe the audio

[Slogra]

Why? Because cd audio/mp3 is way to f*cking loud in contrast, that's why.

Now DVD soundtrack on other hand, have nice dynamics. The difference of soft sound and loud sound is much greater, which is much more impressive. CD audio just sounds flat (everything sounds just as loud).

[Rommyke]

You are right slogra, but if you encode a dvd you have to choose between video and audio
If the movie is not longer than 95 minutes I want it on one cd of 700mb and than I choose a good image quality and a less sound quality and so I use the mp3 sound otherwise I use ac3 when I uses 2 cd's

[Slogra]

I was talking about dynamics/loudness in general (counts for every formats)

[SoonUDie]

If you're ripping from VOB files and use DVD2AVI to demux the audio track, there's a normalization option and a DRC option. DRC compresses the sound so that softer things are louder. I suggest normal or light filtering. Normalization makes sure that the waveform is stored in such a way that it's loud, but doesn't clip.
