Adjusting Audio of MPG Files

[Jiglet]

I'm making a DVD of clips of videos one after another. Some of the videos I've downloaded are much quieter than the majority of them, there's a good ten-fifteen vids with low volume. Is there a program that can go through and automatically fix the audio? I know there are programs like this for MP3s... And if not, how can I do this manually? I wasn't sure if this was the right forum for this and I know it's my first post here so I apologize if this is in an inappropriate forum. Any help would be greatly apprecciated, thanks!

SoundForge is one.


You want to NORMALIZE the audio.

You can use goldwave to batch process all the files at once and maximize that way.

Okay, I got ahold of a copy of soundforge, but it wanted me to buy an MPEG plug-in in order to open the MPG file, which isn't really an option right now - So I got Adobe Audition, and to be honest that seems like a pretty damn complicated program. I'm not a moron and can usually figure this type of thing out on my own but right now I'm clueless - Could anyone help me out here or maybe point me towards some sort of tutorial (I couldn't find any when I looked) - Thanks!

Once you demux the audio and video you can convert the audio to WAV and load that into Adobe Audition. I will try and do this from memory as I am at work. Chose EDIT and Select entire file. Then...and I think it is under the TRANSFORM menu but I could be wrong...you are looking for AMPLIFY. From AMPLIFY menu you want NORMALIZE. You can then select whatever percentage you want to normalize to (i.e., 90 percent or 100 percent) for both left and right channels and click OK. Once the normalization completes you can save the file. You can then use whatever conversion program you want to convert it back to MP2/MPA or AC3 which will give you your elemental audio stream for your authoring application.

Ah, I give up... I never even heard of Demux, I dunno what this stuff is at all. Thanks for the help though!

Hello,

Demux is breaking the video file into its audio/video components seperately. You can use tmpgenc and go to file - mpeg tools - demultiplex. Then open the mpeg file and double click the audio and save it as an .mp2 file. You could use besweet to convert the mp2 to wav if your audio program doesn't support mp2 directly.

Give it a little effort and this editing can be very rewarding. And this site is an EXCELLENT reference source
