Deleting unwanted audio on DVD recordings?

[pzoggy7]

When I've recorded a TV programme on to DVD-RAM or DVD-R, and the announcer talks all over the closing credits/soundtrack, is there any way of deleting this audio?

[videomaniac]

Not without deleting the soundtrack as well.

I was hoping that as the voiceover wasn't part of the original soundtrack, it might be a separate audio file that I could just delete.
But if that isn't possible, perhaps I could fade out the audio before the start of the voiceover. Any suggestions for a suitable program I could use to do that?

Depends on the format, but audacity is free and can do this easily.

They usually play part of the sound track, if you can get it from another part of the movie or somewhere else and replace it if it worth the effort. Also I read lots of thread about taking out voice from a track but I don't think any of them were practical like they were saying invert one channel and add it to the other will eliminate voice.

Pzoogy7,

I am trying to do the same thing as you. Have you figured out a way to remove unwanted commentary / voice overs ?

[guns1inger]

You could try something like AnalogX's Vocal Remover, however you will find in most cases it doesn't leave you with much of the original audio. This is made worse by the fact that the volume of the original audio is usually dropped substantially when the voiceover is delivered.

Replace it with a clean version from elsewhere, or fade it out to nothing.

I am not sure what the last poster means by unwanted commentary - are you talking about DVD or broadcast ?

If you have no need for the closing credits, you could just edit that part out.

Yes, I did manage it - eventually.
There was a lot of learning involved as I'd never used any of the software before.
I had recorded 4 one hour films (Kieslowski's Dekalog series) off TV on to a DVD-RAM disc. The first 3 titles were ok, but on the fourth one an announcer had talked over the closing film credits and music soundtrack.
I had hoped originally to just get rid of the voiceover but it seems that isn't possible. Another option was (as Prot suggested) to just delete the credits but that's a bit crude and spoils the atmosphere of the film.
This is the way I did it, with help from other replies:-
Author track 4 in TMPGEnc DVD Author (TAD), select .vob file from VIDEO_TS folder and Simple Demultiplex in TMPGEnc (freeware) to .m2v (video) and .ac3 (audio) files.
Convert .ac3 file in HeadAC3he to .wav, open in Audacity audio editor (thanks guns1nger), select section of soundtrack to modify and insert Silence.
I could have left it there, but I wanted this track to be similar to the other tracks so I repeated the above with track 1, copied the closing music soundtrack and pasted it on to track 4 where I had silence.
Then convert the modified .wav file back to .ac3/.mp2, Simple Multiplex with existing .m2v file to .mpg file and re-author with TAD. I then burnt the 4 titles to DVD-R, again using TAD.
There's probably an easier way of doing it.
