    Is there a software package that will encode to DD?

    I know DVDit PE does, buy I'm looking for something that will encode audio from MP3, PCM or directly from my sound card. Then MUX it into the video to create a VOB file......

    Is there such a beast?

  2. theres a program called softencode that will create an .AC3 file.
    This file can then be muxed with the video.

    You can open a stereo wav file into softencode then create a 2 channel .AC3 file, then I use SpruceUp to author the DVD, as this will mux the video and AC3 audio together if they have the same name and in the same folder.

    I am currently looking for a way of creating a full 5.1 AC3 out of a stereo source that has Pro Logic, if you have any idea how to do this, let me know.

    ps. I dont think softencode is sold anymore, but you will find it on the net somewhere, just try google

    I use Surecode DVD Pro DTS Encoder to enconde to dts but is necessary the 6 wav files (the six channels) and that what i m loking for a program thah split a ordinary wav into six files(six channels).
    If u know or find that soft please let me now.
    Its more or less the same question.
    Thanks.

  4. You can use BeSweet to convert mp2 or wav to 6x wav.

    I assume you have a 6channel wav to begin with?

    I there anyway to extract the extra ProLogic channels out of a 2 channel stereo track, these can then be added to there own channel?

  5. Soft Encode will also do 5.1 channel DD ... not just 2 channel... all you have to do is import 6 .WAV's and select which channel you want each .WAV to correspond to before you encode...mono .WAV's will imoport as 1 channel and stereo .WAV's will import as 2 channels...

  6. There are two versions of SoftEncode... one only handles one or two channels and the other does the full 5.1

  7. I know I can import 6 wavs to softencode an create a 5.1 AC3, but what I need to do, is get the 6 wavs.

    If you have a 6channel file, you can use BeSweet to convert it to 6 wavs, but If you just have a 2 channel file, how can I get at least 3 wavs out of it.

    2channel stereo can have Dolby Pro Logic encoded into it, this is a centre channel and 1 rear channel....There must be a way of extracting the centre and rear channel out of a 2 channel sound file..

  8. I tried to buy Sonic's Foundry's Soft Encode (Either version 2.0 or 5.1) and it's no longer being sold. Sonic Foundry claims that future versions on Vegas Video "might" include the Dolby Encoder now that home DVD authoring has taken off so well. I was able to find several crack version of the program online. Not sure if because it's an old program, but when I try to encode, it starts working, and then just vanishes off my screen. Not blue screen, no error messages. Just vanishes! As if I closed the program. I locate the new *.ac3 file, and it works for a few moments, obviously only up to the point where the program ended during encoding.

    I tried using Soft Encode 5.1 with Win2K, WinXP Pro Edition, and ME. It had the same vanishing effect on all systems. I'm very curious if it will work on Win95 or Win98. Half tempted to install Win98 on an old system of mine just to test it out.

    If anyone else has had this problem let me know, or if your running a Win95 or Win98 system and want me to send you the program to do a test, let me know.

    Ok Ok Ok, I know I'm not as smart as all of you. But look how much smarter I make you look!

  9. I have not had this problem with SoftEncode, maybe you got a dodgy crack for it.

    I have succesfully created an AC3 with 2 channels.

    Have you got the right codecs installed, try NIMO Codec Pack v.5

    What i wont to do is create a dolby digital file 5.1.
    But i only have a wav whith to channel and i want to make it 5.1 but i cannot find any software that do that.

  11. Man7, you want to create a 5.1 file from a 2 channel file??????

    If so, this is what I am trying to do, If you get an answer, let me know

  12. I have just found an option in Softencode that will encode Dolby Pro Logic into a 2channel AC3.

    I am testing this now, and will post results tomorrow.

    This is what I was really looking for, as I have a 2 channel stereo track with Dolby Pro Logic, I originally thought I would have to decode the rear channels and load them as seperate channels into softencode, but no, I just create a 2channel AC3 with pro logic built in.

    I have 1 more question though......

    It asks if the original source has Pro Logic, how can I see if a sound file has pro logic in or not, is there an audio checking program to do this?

    cheers

    You guys are failing to answer the question.

    A stereo file that has Dolby Surround information in it is a stereo file with "surround" information matrixed in such a way that a Dolby Surround or Pro-Logic decoder can properly interpret the matrixed information. Furthermore, "Dolby Surround" is analog; "Dolby Pro-Logic" is the digital implementation of "Dolby Surround".

    If you were to find a software application that properly decoded the matrixed information, you'd be a better man than all of us here! If you did, the maximum number of "channels" you'd be able to extract are 5 (not 6 -- thats why we have Dolby Digital now, to get six channels). You'd also need to know this basic of matrixed audio:

    For Dolby Surround, the matrixed field is made up of L, R, L+R -- these are the three front "channels" ... and L-R (el minus are), a signal when decoded thats routed to the rear speakers. There is no LFE component in this matrixed stereo signal.

    Again, best of luck finding software that will decode a properly matrixed Dolby Surround stereo file.

  14. Dolby Pro Logic is not a digital format, so as far as I understand, there is no extra info hidden somewhere in a Dolby Pro Logic WAV file...Dolby Pro Logic is simply mixed in a way so as to simulate surround sound using 2 channels...it is essentially just a stereo WAV file that is equalized in a specific way so as to create the illusion of a surround environment...there are not 5.1 discreet channels of sound in Dolby Pro Logic

    ...in my experience, if you encode a 2 channel WAV file to a 2 channel AC3 file, even if the original WAV was mixed in Dolby Pro Logic, then you are only going to get sound out of the front left and right speakers of your Dolby Digital set-up...

    ...as we know, Dolby Digital has 5.1 (6) seperate channels of sound...there is no way that I know of to truly extract these 6 original channels from a 2 channel WAV file, but there might be a way to simulate it...

    when I have simply wanted to get a 2 channel WAV to play in Dolby Digital out of all the speakers, I extract the 2 channel WAV into 3 seperate Mono WAV's:

    1 is the left channel alone, the other is the right channel alone and the last one is both channels combined into 1 Mono channel....

    I then import all three channels into softencode twice...I use the Mono channel for the front speaker and subwoofer, the left channel for left front and back speakers and the right channel for right front and back speakers...it's not at all like true surround sound but it is 5.1 Dolby Digital and it sounds better than Dolby Digital 2.0...

  15. by the way Neishaverse I have had the same problem with softEncode in windows 2000...for a long time it worked flawlessly, then it would nearly always crash leaving no trace...I never figured it out, but
    i figured it must be a conflict...it can be a picky program...I tried different versions of the program and, for unrelated reasons, I eventually reinstalled my operating system and I haven't noticed a problem...you should try searching for other versions of the same program to download as there are different releases out there....

  16. ...in my experience, if you encode a 2 channel WAV file to a 2 channel AC3 file, even if the original WAV was mixed in Dolby Pro Logic, then you are only going to get sound out of the front left and right speakers of your Dolby Digital set-up...
    Like I said earlier, in soft encode, when you choose an output of 2,0 (2 front channels) there is an option to include Dolby Pro Logic.

    I have seen original DVD's with only 2 channel digital sound, but with Dolby Pro Logic.

    The only thing I need to know, is, whether a 2 channel source has Pro Logic or not. I dont know what the outcome may be if I choose Pro Logic in softencode when the source doesn't have it.

    I suppose if theres no software to tell me this, I'll just have to burn it to a re-writable, listen to it on my system, and see if I hear any rear effects when in pro logic mode.

  17. My understanding is that Dolby pro logic is an analogue system that encodes the Surround info into the normal stereo soundtrack. If your source file has dolby prologic encoded into its normal stereo soundtrack it should still be there when converted to a differnt format, though lossy compression methods such as MP3 may lose some of that. I have converted many DIVx movies to DVD and played on my DVD player, my Home Theater amp recognises the audio stream as prologic and decodes it, though it is nowhere near as good as true 5.1. I do get sound effects out of the rear speakers though. This is independant of the audio format on the disc (.mp2 on VCD's and PCM or 2chan AC3 on DVD's).
    Even if a piece of software could extract multiple wavs from the stereo soundtrack (after all thats what the decoder is doing), you cant improve on the source material and all you would get is Front left, centre, Front Right and rear. If you were to get 5 channels out of your soft encode the two rears would probably be identical, as this is what prologic provides.

    just my .02 cents as they say!

  18. being able to get 4 channels out of a stereo sound track would be great, like you said, you would have front left, front center, front right and a mono track for rear that could be used for both rears.

    Anyway, I have succesfully created a DVD with Digital 2 channel sound, and you can select Pro-Logic on my amp and get pro-logic sound from the 2 Digital channels.

    All I need to know now, is what would happen if I encoded a 2 channel Digital AC3 with Pro-Logic, when the source has no pro-logic encoded in it.

    Does Pro-Logic actually get authored into the stereo signal when a film is made, or can ANY stereo signal give Pro-Logic?

    dvddarren,

    Any Stereo source can be decoded with a Pro-Logic receiver.

    It woun't always sound great, but you will get some surround action.

    I actualy like to play The Beatles with Pro-Logic turned on.

    As far as I know, encodeing to DD will not erase the Pro-Logic info, You may need to MANUALY turn Pro-Logic on if the encodeing software does not set the BIT to tell your receiver to turn it on.

    P.S.
    Thanks for all the info fella's, I'll start searching for the software suggested... any hints??? PM me!

  20. cheers gNOMEintheRedHat, now I know

    I think the option in SoftEncode for dolby pro logic, is, like you say, to put a tag for it to automatically turn the amp to prologic (It worked on mine).

    As for getting the software, try searching on Google

    Now I have another propblem, I need to extract AC3 sound out of a divx avi that has 5 channel AC3 sound.

    I have tried vdub but only get either 2 channels or very choppy audio.

  21. for anyone interested, Pro-Logic is a decoding method, not a digital anything. the simple way to extract surround information from a 2-ch wav, get a program like cool edit, or some other audio (wav) editor.

    to keep things compatible with non-surround decoders, leave the L and R channels intact.

    to get the C channel, add the L and R into one mono file.

    to get the S channel (surround is mono in pro-logic), invert L and add it to R. (or vice versa, the point is that the surround is out-of-phase, so you need to subtract the channels, or add them with one inverted/out of phase)

    there's actually a 3dB difference between the L/R and C/S channels, but just normalize the volumes of the channels to whatever you deem appropriate.

    then i guess you'd just use the S channel for both RR and LR in 5.1. you could create a LFE by running the C channel through a low pass filter (such as 60/80/120hz - 120 is, i believe, the DD standard, but depending on your subwoofer it might sound better filtered lower)

    while this method probably isn't optimal, it's more than adequate for making a 2ch into a 5.1.

  22. I didn't read the whole thread so this may have been mentioned, but Scenarist has a pretty desent ac3 encoder with it. It will go from a few audio files(wav, mp#, pcm, etc.) to ac3. Its actually pretty good, so find it and see if thats what your looking for.

  23. how about this?? this should be easy? if i rip a DVD with either DD or DTS, how can i keep it in that format and burn it onto a CDR? does the audio file need to be encoded and if so with what?? can i reduce the bitrate and still keep the same format??? if there was a way to take a Pro Logic stream and convert it to a DD stream then i have MANY captures that scream for it........thanks for the info...........
