can you extract audio channels seperatly from DVD?

[xeb]

probably a dumbass question, but can you rip off the different 5.1 audio tracks seperatly from a DVD if you have a DVD-ROM? might be useful for grabbing vocal samples when the vocal's front and centre and background noise is on the surrounds....

I dont see why not, but specifically what you mean by "audio tracks" is what I would like to know. Are you looking to remove background movie noise, music etc. from the sample and just extract the vocals ?? That can be achieved at a later stage but I dont know how to do it directly from teh dvd player.

I would just plug in the audio outs from the DVD player / line out from your sound card if using your DVD ROM and jack it into your recording device. You could also use the headphones connection at the front of the dvd device and plug it into your MIC / LINE IN of your video card and record it.

One you have saved it as an MP3 / WAV file, you can use your fav audio editing tool to manipulate it as you will.

when i say different track i mean the different channels... i want to rip the cleanest possible vocal and it seems to me that vocals are generally put out on the frront speakers, while you get more background sounds from the rear surround speakers. i'm not sure if that means less background sound is put through the front channels, but thats what i'm hoping.

my DVD player has an internal amp (probably a mistake in hindsight but it was cheap) so theres only speaker connections out... i suppose i could wire up a speaker lead with phon plugs on one end and bare wire on the other and take that to my PC (not sure abotu quality though). what i'd really like to do is rip it direct form the DVD if thats possible (as in WAV extraction straight from an audio cd)... if thats possible i'd consider getting a DVD drive for my PC (no 5.1 surround though)

ok I get what you're saying and I DEFO see the prob in your case, recording in 5.1 format might yield some strange results in playback cause you'll have the sound thrown around toward one channel, kinda like playing a movie with 2 speakers when you're output is set for 5 channels.

Try play the movie in 2 channel mode on the dvd players of your comp and record the stream..... see if that works for you

This is definetely possible. You'll just have to find the right tools and do a bunch of research. Check these sites:

First you will need to Decrypt the .VOB files you want the audio from (which are Video and Audio sync'ed/muxed together). You can use DVD Decrypter for that. Then you need to get a VOB editer to Demux the audio from the VOB, and then you will need to find a program that ripp's the AC3 file (5.1 Channel audio format) into its seperate channels.

I'm not entirely sure, but I think AviSynch may have this functionality. You may have to use it in conjunction with BeSweet after you ripp each individual channel.

I recommend you go to the forums on www.doom9.org, sign up and then search for this sort of thing. If/when you don't find anything, you can post your question there and get much better results.

nah thats exactly what i do want... to rip off one channel that has the vocal with less background noise... i can rip the audio straight using audio outputs on the DVD player, but that will give me all speakers combined so i'll get all the sound thats being thrown to the surrounds that i don't want

thanks civic.... sounds proper complicated... maybe i'm just best wiring to one of the speaker outs.... will have a play tonight..

cheers for the help dudes

Well what I'm explaining for you isn't using any hardware. All you need is the DVD you want the audio from, and a DVD-Rom drive on your computer. Insert the DVD into your DVD-Rom drive, open DVD Decrypter, and Decrypt the DVD. The rest after that is a bit complicated, but its going to be the easiest, and fastest way to do it. All you need is the right tools. Good luck.

i used to extract dialogue from dvd's a lot.
they were always fun to play at parties, or just whenever.
they make for clever tools.
if you're using some serious gear, you can even 'gate' out some of the background noises.

[asdf_admin]

noise gates are sweet. they can help you much. :wink:

[superEGO72]

search for depeche mode - enjoy the silence acapella and youll hear what it sounds like.

can certainly be cool to extract neat parts from movies though.

[Balanc3]

Yes. I have 2 programs. Smartripper and Flaskmpeg. Smartripper gets the raw data off the dvd (the VOBs) and flask will allow you to extract the individual audio tracks the way you want. For further editing, cropping, etc I use Virtual Dub. If you pm maybe i'll be nice and send you the whole package in a zip file

You could probably also just play the DVD on your computer, and rip it using totalrecorder or some such tool. I think most sound cards allow you to adjust volumes and balance on your channels so just mute the unnecessary ones and pan over if needed.
