Removing Select Audio Sections (Splitting Audio Channels?)

[christopheramos]

Hello!!

I have a video that I would like to cut out small sections of audio here and there, but leave the video intact. In other words, I'm trying to cut out some spoken lines in a few places, and hopefully keep the rest of the audio and video and keep them in sync.

I'm thinking I might need a program that (after I demux) allows me to edit the audio (and maybe even split the audio in different channels, allowing me to cut out just certain parts while other background audio remains untouched).

Does anybody know if such a thing is possible? And, if so, what tool to use?

PS: My editor (DVDLab Pro) produces a singular AC3 file and an .MPV file after I demux video from .VOB format.

Thanks so much!!!!!!!

Regards,
Chris

First, DVD Lab Pro is not an editor. It is an authoring program.

In order to do what you want to do you will have to

1. Demux the AC3 audio form the VOBs
2. Demux the mono channels from the .AC3 file
3. Load the first channel into your audio editor and locate the part you want to remove.
4. DO NOT CUT THE AUDIO. This way leads to madness and hell. Either drop the volume to zero for the duration of the part that offends you, or put a sound effect over the top. There is no need to cut the audio, and the best way to avoid sync problems is not to cut it.
5. Repeat for each mono track, as the same audio may appear on multiple tracks.
6. Re-encode the audio back to an .AC3 file.
7. Either remux or re-author your AC3 audio back with the video.
8. Question whether or not the whole exercise has been worth the effort.

Okay, thank you. So it looks like I am going to need 3 things:

1. A program that allows me to demux my AC3 file, once
I demux my .VOB file, into one or more mono channels?

2. A program (audio editor) that allows me to lower the mono audio
during selected parts, then

3. A program that allows me to re-encode the audio back to an .AC3 file?

Does that sound right? And what program(s) would do that?

Thanks so much!!!!!!

belight (a GUI for Besweet) should be able to extract your mono wav files, and recombine them to AC3 files afterwards.

Wavepad or Audacity can be used to adjust the volume.

soundforge is a really good sound editor. If you can isolate the soundtrack you could then make a copy of the background noise where there is no talking, and then paste it over the voice you don't want to hear.

Okay, thanks so much!!! I have only one question left.

What version of BeSweet do I use Belight with? I downloaded Belight, but there are a number of different versions of BeSweet out there (BeSweet v1.5b31, BeSweet GUI v0.7 b4, BeSweet Batch, and BeSweet CLI ). I'm not sure which to use

(i.e., what Belight plugs into).

Thanks!!!!!!
