mr9ParticipantHowdy all,
I know that this can be done, generally isolating certain channels will give the desired effect but having trawled the net and been baffled by tech speak, I cant seem to figure out how to do it and then save it as a separate audio file…..any bright sparks know how its done…the simple way….
Cheers

TiMGParticipantthere isn’t a ‘simple’ way .
atleast that i know ofa possible method would probably involve phasing and filtering (knockout) different combinations of the 5 channels.

leeroyparnellParticipantI’ve got a few DTS cd’s that I’ve been messing with… those mixes aren’t really any better than using a stereo file, because the center channel is never just vocals… i’ve pulled audio off dvd’s too, it’s the same deal.. if you try cancellation methods, it won’t work either because none of the other channels contain the audio you need to subtract from the center channel

DJ-NightParticipantI can’t say there is any easy way of doing it. And there’s a 50/50 chance of getting a clean pella from the center speaker since various labels master their 5.1 audio in differnet ways. I know that all Michael Jackson DVD’s are perfect to use. So anything from Sony will work I guess.
First thing is to extract the main VOB files from the DVD and then get a 5.1 mixer software (like Soft Encore 5.1), then just mute all the channels except the center one. Save as a wav file.
It’s a time killing process and as said, there’s a 50/50 chance of getting a clean pella without various soundeffects and etc, depending on the DVD and what kind of footage it is. So don’t bother trying live videos. But if the Michael Jackson DVD’s works perfect, try anything from Sony…

leeroyparnellParticipantit’s less to do with the company who put it out and more to do with the exact engineer doing the 5.1 mix… it might work somewhat on pop dvd’s, but with anything like rock music you’d have to use a combination of the center channel and one of the left or right front channels (or a blend of the two) with a VST like that kn0ckout program to spectrally knock out any of the music that’s in the center channel (every rock DVD/DTS CD/SACD/DVDA I have isn’t just vocals in the center channel)

mr9Participantthanks guys,I know the Lennon Legend DVD can be done but it seems to take for ever and a day to split everything…….worth it in the end I suppose…

Morbid MatronParticipantThere are also programs (can’t mention one right now, i don’t remember), with the ones you can rip directly from the DVD just the channel you want (center, rear left…).
You can try and search one prog with this characteristics.

leeroyparnellParticipantthe process i usually use is a program called DVD 2 AC3, then I use Hypercube Transcoder to separate the channels into their own wave files.
It’s still pretty useless though, it’s very rare for DVD audio to be mixed in any way that can be used for acapella making.
