[cokeman]

hi guys

i been having promblems with the dolby digital plug in for nero 6 ... i encode a movie(the movie sound track is in stereo) using nero express 3 and select audio channels to 5.1ch ...eveything gets encoded alright but when i play the movie on my dvd player home therther the vocie channel is coming from the centre ,front left and front right...it should be ONLY coming from the centre speaker ...the background sound works perfect with all the movie sound action effects ......i dont know how i can get the vocie channel just to centre speaker ,is there any configuration that needs to be done manual ???

please tell i ve serched all over the net but seems ive only got the promblem

i have found the way to configure the dolbly digital plugin ....can anyone tell me the settings so the vocie channel is ONLY coming from the centre speaker ..otherwise i just keep trying myself heres a photo snap of the configuring section in nero plugins for dolbly digital:

So you are feeding in a standard stereo audio track, asking for it to be output as 5.1, and wondering why it is smart enough to work out for itself what is dialogue, extract it to a centre channel and encode it accordingly ?

Any other miracles you would like done by this magical software ?

You cannot automagically turn stereo in multi-channel surround, especially with something like Nero. The best it will manage is to try to isolate signals which are even down the centre, and assume they are dialogue. This ia big assumption, even if it tries to limit based on frequency ranges. If you want to try to convert stereo to multi-channel, you need to do it by hand, and even then there are no guarantees that you will get what you want, as you simply don't have the right source material.

As a general rule, Dolby ProLogic II will do a much better job on the fly from a stereo source than you will do in software.

yeah gunslinger
i am trying to put stereo ac3 movie soundtrack to 5.1 dolby digital ....i have tryed on 2.0 dolby digital that works fine the vocie channel is only coming threw the center speaker the way it meant to ....its not working for 5.1 like i told u ...
i dont see the dference much if it works fine on 2.0 digital then why not on 5.1...u said that it will not notice the vocie channel on 5.1 why is it only coming from the FL ,FR,C ..it should be coming from the rear channels as well..

also have u notice in the photo attachmaent theres the vocie dialog button??? whats that all about .....

is there any software that u recommend that will do the job and not take all day?

There is no simple, miraculous way to do this. You simply do not have the source material required. The simplest solution is leave it stereo, and play it through a DPLII amplifier.

To be precise. U need a dolby prologic II downmix. Not just a stereo signal.
Usually audio material, available on a DVD as dolby digital 2.0 is such a DPLII downmix.
however you can prepare your own DPLII downmixes using original 5.1 source.

Also, DPLII decoder is just an algorithm, and can be embedded in a hardware home theatre amplifier, as well as in a software application (such as PowerDVD, or Aud-X DSfilter).
Anyhow, if you have a hardware amplifier which does DPLII decoding, than it makes no sens
to convert it to 5.1 (AC3), 'cause your amp can handle the decoding in real-time (as guns1inger suggests).
