How to normalize multiple audio files ?

[najor]

Hi,

I just authored some videos into one DVD (DVD-lab Pro 2). When I playback the DVD on my desktop player I noticed the audio volume between the various videos are uneven (some are louder than others).
So how do I make these audio files sounded at the same level (normalize) before authoring them?

Thanks b4.

If mp3 audio you can use mp3gain.

Try the Vob_Gain script on the bottom of this page.

the audio volume between the various videos are uneven (some are louder than others).

the levels must be adjusted using the "dialogue"(converstion) as reference.
only "normalizing",will give you equal levels but the dialogue between videos will stay differents...in one video the conversation stay loud and in the other will stay low.
have one interesting thread in doom9 about this topic with "how to" in the first post and can be used not only for DD but to get seamless levels between differents videos like in your case:
