Converting WAV file to Dolby Digital® 5.1 Surround

Converting WAV file to Dolby® Digital 5.1 Surround

Using tool Vegas 5 make 100% DVD compliant 5.1 Surround AC3 files.

Important note: to enable Dolby® Digital plug in Vegas 5
you need purchasing DVD Architect or ac3 plug-in

In this guide I convert 2 channels WAV file to 5.1 Surround AC3 file to hear in all speakers not only in front speakers.

















The configuration of the Dolby® Digital plug


To convert from Dolby® Digital 2.0(2 channels) to Dolby® Digital 5.1 Surround,
you need convert AC3(2 channels) file to WAV (2 channels)
for guide without losing sync and quality click here.(TMPGEnc Sound Plugin required)
The VEGAS not importing AC3 files.

Ok like BJ_M wrote:
i.e. for a simple stereo -> 5.1 , you put the stereo track on 5 audio tracks and in each you select (L only (pan to 70-80% left)) - (R only (pan to 70-80% right)) - repeat above at 12dB down for rear surround tracks (add small reverb or delay) - (R+L (LFE channel))

for center -- add nothing .. or add a track and (L+R) 18dB down pan center
END OF STORY.

So when a wave file is made from a dvd and then back into Dolby 5.1 does it not defeat the purpose or are you saying that dvd architect simulates the effect of dolby 5.1. I ask because I always thought of it as encoding a mpg 1 file to mpg 2 higher bitrate(basically the details is already lost)

[Mrsash]

by the way an excellent guide and effort.
thanks

it's definitly a good guide, but what's the use of faking 5.1. The only thing you do is forcing a stereo sound to be played out of 6 speakers ?!?!? You won't get a 5.1 effect with it, so IMO it's better to stick with DD2.0.

[Red96TA]

If you're going to use the DD track in DVD-Lab, make sure that you select 'none' under the preprocessing tab...if you don't, the menu and track audio will be different volumes.

Good guide, but it's only a copy of the Vegas help file which comes with the software.
It is nice to see 5.1 ac3 on a timeline of an authoring software, but if a source is a stereo, you get no real surround sound.

[edDV]

Good menu tour but you could at least add some generic ambient sounds (or maybe a laugh track?) to the surrounds and some percussion to the center and LFE.

[BJ_M]

often rather pointless to do for a stereo track -- and in fact the incorrect method (sorry, but you are way off) ... your alcons would be awful in the method above and the ac3 surround not proper.


in vegas - you should duplicate the tracks and select which channel ...

i.e. for a simple stereo -> 5.1 , you put the stereo track on 5 audio tracks and in each you select (L only (pan to 70-80% left)) - (R only (pan to 70-80% right)) - repeat above at 12dB down for rear surround tracks (add small reverb or delay) - (R+L (LFE channel))

for center -- add nothing .. or add a track and (L+R) 18dB down pan center





since this is not a correct guide - we should mark it with the mark of Zorro

[BJ_M]

oh yes - another thing, you dont need to purchase DVDA to get ac3 ..

you can still buy the ac3 alone lic from sony .. but for another 100$ or less , you might as well get DVDA

fake surround? What about the old music titles like beatles? how did they convert it to surround?

[edDV]

Early Beatles Stuff had 4 track masters. Voices were layered. If they kept the intermediate passes, then more
tracks might be capable of remix.

Mid Beatles (late 60's on) work has 8 and later 16 track masters that can be easily remixed to 5.1

For 50's stereo and mono recordings, they use cheezy frequency separation filters. To my ears, the result is worse than the original. I'd rather have some current session band provide some punched surround, or just forget it.

Ok, Sorry.
I thinking its simple, the Vegas make mixing automatic to 5.1.
I update the guide later, after 6-7 days or less.

Is there a way to do this with a 5.1 channel WAV?

What I'm having to do now is demux the 5.1 AC3 to separate files and then drag all of them into Vegas in order to edit a section of a 5.1 project.

[BJ_M]

actually all you have to do is to drag ONE of the mono waves files into Vegas ...

edit your project - keeping that track in sync

the render that track out as mono .. ... then in media explorer , right click on media and replace with next track --> render that track out (mono)

repeat for all 6 tracks ..

you will find this is very quick ...


when done - and have the 6 new tracks -- start a 5.1 project in vegas..

load new tracks

pan to correct position each track

render ac3 5.1

I would like to do what you have suggested but I'm confused.
Could u post some pictures showing what you described.
I tried to do it the way the original poster said to do it, and it didn't come out to good.
Any help on this matter would be greatly appreciated, as I have been looking for ways to convert 2.0 to 5.1 for a long time
Thanks in advance

I'd like to make the back speakers focus on the music & front speakers to focus on the speech. How do you do that with this program?

Thanks

[guns1inger]

You have to have your music and speech on different tracks.

Real surround sound isn't magically pulled from a stereo track. It is made up of lots of individual elements that are carefully placed in the sound field. If you record your dialogue and music separately then you can mix them as you need to. If you have a stereo track with everything already mixed, or you only have the recording from a single camera microphone then you really have very limited options. You can try to use EQ filters to separate out some of the frequencies to see if you can isolate enough dialogue to create a centre channel, but it will usually be muddy at best. True surround sound needs to be planned for fro the outset, not done as an after thought.

Is there any way to encode a pair of .wav files, one stereo front, the other stereo rear, into Dolby or other surround format for playback through a standard home theater system?

If this question has already been answered, I would be thankful for the reference.
