    DTS and AC3 are different formats, internally they are different, each one with its own metadata. But I'm not an audio expert, i.e., I'm not a low end programmer

    Maybe someone in this forum can help you in that, explaining what is inside each format

    Put in here a sample where that occurs

    Maybe it's something with a particular source

  3. Hello,

    This is a great tool that saved my life when I realized that my brand new LG TV is simply brain dead without DTS support.

    One issue I have is that the sound is distorted in some movies. Not a show stopper. The distortion seems like a clipping effect. High frequency chirping is coming.

    Is there a workaround, some settings that will avoid this issue?

    Thanks

  4. Hi

    First of all - thanks a lot for your effort in developing this tool, it is very much appreciated!

    I've been utilizing it for quite a while (using the aften method) but today - for the 1st time - I've encountered a problem. After audio extraction from source is finished, the following message is displayed numerous (many!) times in the log screen:

    "ERROR ! Try the other method of convertion"

    What's also strange (and maybe related?) is that under "Video info" it shows "Length: 0H 0M 0S (0)" (though the FrameCount is 189920) and under "Audio info" it shows "Bitrate: Unknown" and "Delay: 0 ms".

    Another thing that may be related: the Audio Type is "A_DTS" (I don't remember encountering this type, only "DTS").

    Obviously the file plays normally (including sound and all) on my computer.

    What does the message mean? Does it mean I have to switch to the eac3to method (I'd rather not, due to the normalization option in aften) or is it something else?

    Thanks

    try the other method, eac3to and see what happens

    As I said before and many times, MKV2AC3 uses 2 methods : AFTEN and EAC3TO, other converters uses only one and that is EAC3TO

    You should be able to work with both and choose the best for you, AFTEN is very sensible with your codecs configuration

    A user reported me that EAC3TO method was not working with some sources like this one :

    http://www.mediafire.com/?h6535ahicc9ssxp

    A error was generated by EAC3TO saying that was unable to downmix, i.e., it failed the conversion

    I build a fix that solved that problem, just replace MKV2AC3 executable file with this one :

    http://www.mediafire.com/?2amfrgue265dz4a

    update only if you experienced any problem like that, anyway this update is cumulative with other fixes above.

    Hi,

    Great application which saves a lot of steps and time. I just wanted to know if you have posted the source someplace. I'm thinking of porting this to Linux. I'm not sure if its doable but want to try.

    If it is fine for you , can you post the source somewhere if not already done.

    Thanks.

    this is a .NET application, so it is possible to run in Linux using Mono Framework

    but the problem is MKVToolnix, and other external tools

    Thank you for the instant reply. I do not want to use mono. The aften, dcadec and mkvtoolnix are available under Linux.

    My assumption is that to get the AC3, extract the DTS track using mkvextract, use dcsdec to get WAV, use after to get AC3 and then remux using mkvmerge. I'm trying to understand the importance of timecodes as you also seems to extract this information.

    I'll do some more research on this and decide if it is worth doing.

    Any input on the above conversion process is much appreciated.

    Anyway thanks for the reply and you really helped me to watch most of the movies in my HDTV . Thanks again.

    Note: I'm reading http://juliensimon.blogspot.co.uk/2009/01/howto-processing-multichannel-audio-dts.html to get an idea.

    Thank you for all of your hard work. I love this so much. It has made my life a lot easier. I use XBMC DLNA capabilities on my main desktop to stream to the GTVBox app on my Google TV Logitech Revue. The revue and dts are not friends so I will basically be converting every movie and tv show mkv that I acquire with DTS to AC3. I have zero complaints just a couple feature requests.

    --"Delete source when finished" check box
    --The ability to not add _ac3 on the end of the filename
    --"Destination Folder same as source" option
    --Possible folder scan option to recursively scan an entire folder and add only the mkvs with DTS audio

    Thanks again!

  12. I am getting below error.
    ERROR ! check if you have a 64bit MKV2AC3 version. Conversion from string "8 / 6" to type 'Integer' is not valid.

    Previously one user got similar error (7/6 integer not valid). I am not able to get that download link for MKV2AC3.exe suggested for that issue.
    Please suggest. Usually this program works for all most all mkv files. This file has Audio DTS HD.

  13. I have exactly the same error:

    "ERROR ! check if you have a 64bit MKV2AC3 version. Conversion from string "8 / 6" to type 'Integer' is not valid. "

    Of course I do have 64bit version installed. I have re-installed it just to make it sure. Unfortunatelly the error is still there :/

    Does anyone solve the issue and could give some hints ??

    Thank you in advance !

    Don't you see the update link above in post #97 ? can be used for 32b and 64b
    Quote Quote  
  15. OK - I am really sorry - I didn't know that #97 refers to this problem :/ I have seen a similar issue in post #72 but the file link is out of date.
    Anyway - now the program runs smoothly - I am doing some conversion right now to test it out.
    btw. an AWSOME job !! This software rocks !! My LG is not so Smart as it's written (DTS is not playable) and that is why your software is a lifesever !!! thank you !

    The updates are always cumulative

    anyway it is time to make a new build with all later fixes announced it this thread

    There is nothing new, only a fresh rebuild with all fixes build-in, therefore there is no need to reinstall the application if you have all fixes already installed

    -----------------------------

    Version 1.03.04 - release date : 30/10/2012

    changelog :

    (FIX) Conversion from string "number / number" to type 'Integer' is not valid.
    (FIX) EAC3TO Downmix failed with some sources
    (FIX) AFTEN method failed to convert from DTS 2.0

  17. Glad to see it supports Drag & Drop from Explorer. I have to agree with the last person to comment in the app's download page comment section. The only thing a bit disconcerting is not having a clue when the audio conversion will complete. Some kind of progress bar or even just a log entry every 10% would eliminate the uncertainty.

    Thanks for the program. I'm using it more and more lately.

  18. Hi.
    Thank you for this great tool.

    I have only a little problem with all the converted mkvs: they have "header stripping" in the second audio stream.
    I know I can remove the header stripping with mkvmergeGUI, but it would be easier to do it with MKV2AC3 directly if you can set the program that way.

    Thank you again!

    it does that automatically for each stream

  20. In my case, I use the 64 bits 1.03.04 version and it removes only the "header stripping" from the first audio and video stream, not from the other audio streams of the mkv.

    Thanks again.

    Why do you say that ?

    I mean, the "header stripping" was always removed and I checked the code just for confirming and it is : video, subtitles and audio

    Why do you say it isn't ? do you remux all again ? or do you keep original streams checked ? because what is original stays original

    this program uncompress video, audio and subtitles during the remux stage but only the streams that are selected ( video is the only stream that is uncompressed always by default )

  22. It always happens to me if the source have two or more audio streams.

    I have just used MKV2AC3 to convert a mkv with three dts audio streams without header stripping. I have selected all the video, audio and subtitles streams and I haven't checked "keep original streams". I have used the eac3to method.

    The resulting mkv has the video and the first ac3 audio stream without header stripping but the second and third ac3 audio stream have appeared with header stripping. And this is a problem with my mkv player.

    I don't know if this only happens to me and I don't know why.

    Thanks for all your interest.

    wavi is a external program, for some reason it doesn't work in your system

    you should use the other method : eac3to

    mkv2ac3 can use both
