Low Audio in DVD

[m7r23]

Hi, I'm wondering is there a way to raise the volume in DVD's. One of the movies, which is in AVI format has a very low audio and I cant here nothing when I play it back in my DVD standoalone player. ANyways with any tutorials.

if you are watching Avi(divx) on your dvd/divx player, load your avi into virtualdubmod and demultiplex the audio to wav and the video to avi.

open audacity load the wav into it and select an option there to raise the volume and then save it as mp3.

open virtualdubmod again and load the avi you demultiplexed before, click on streams and then stream list uou should see in avi here click on add on the right and add your raised audio.

click on the video tab and select direct stream copy

save your video

i think its this

hope it helps

Alright, I'm going to try that. It seems like a long process though. On average how long does that take.

[ricardouk]

well done that for some dvd episodes i had and it took me 5 minutes for everything, i suspect 2 hour movie will be around 15 to 20 minutes

virtual dub doesnt encode anything , just demultiplex and multiplex the avi , what takes longer here is the audacity step

good luck

You can also try Sony Vegas to raise the volume. Just right click on the audio file and choose normalize. If that doesn't work you can set some points with the mouse in order to raise the volume. O que você acha Ricardo?

Olá\Hi Cunha

i havent tried Sony Vegas, but to me normalizing the audio means comparing the high audio moments and the low moments and place the audio level in between.

he said he had a low volume avi so i think that wont help him much(but im not an expert)

[Cunhambebe]

Vegas can normalize the audio for him and besides he can insert an audio bus and.....there's still Sound Fourge which is Vegas' Default Audio Editor. Plenty of possibilities.

[ricardouk]

like i said i never tried sony vegas,so im not aware of its possibilities.

the tools that i mentioned are both free, sony vegas and sound forge arent.

no need to buy top professional tools just because of one avi.

Ora pois pois...of course, my Portuguese friend - lol.....You're right fella...There are a lot of freeware that can do a great job.

[ricardouk]

Ora pois pois.... Oh yeah

he hasnt come back to say if it work yet.

So, if you already own SoundForge and Vegas, which of those two would you use? Offhand, I'd demux the file, normalize audio in SoundForge (where I have a ton of plug-in effects and filters) and remux. Is that too involved of a process? I've actually done it recently.

[Cunhambebe]

I would use both. Please note that Sound Forge is Vegas' default Audio editor. I guess this fact can answer lots of questions.

- This would be perfect, but you can choose. If you just want to normalize audio levels you can do that in Vegas (to raise volume). If you're having some clips, then I would use Sound Forge and its plug-in Clip removal. It's just the right thing to do.
