  1. I have an mkv file that does not output sound on my tv because of the audio format. Looking for a solution. thanks
    So far i demuxed it and tried audacity and a couple of other programs to convert it but what comes out is just noise

    When i open the file in any audio editors it says it cannot determine the format and it's asking me to choose attributes and rate (hz). I only know this:

    Code:
    Audio #1
    ID                          : 2
    Format                      : TrueHD
    Codec ID                    : A_TRUEHD
    Duration                    : 1 h 59 min
    Bit rate mode               : Variable
    Bit rate                    : 3 659 kb/s
    Maximum bit rate            : 5 634 kb/s
    Channel(s)                  : 8 channels
    Channel positions           : Front: L C R, Side: L R, Back: L R, LFE
    Sampling rate               : 48.0 kHz
    Frame rate                  : 1 200.000 FPS (40 spf)
    Compression mode            : Lossless
    Stream size                 : 3.06 GiB (20%)

  2. ffmpeg -i "input.mkv" -map 0 -c:v copy -c:a ac3 -c:s copy "output.mkv"
    or
    ffmpeg -i "input.mkv" -map 0 -c:v copy -c:a dts -c:s copy "output.mkv"

    Or from TrueHD to FLAC with AudioMuxer. Saves space.

    PS: You have to update manually the files at "C:\Users\UserName\AppData\Roaming\AudioMuxer" , because they're not up to date. The files that gets installed are way too old.... Eac3to, libFLAC.dll, mkvmerge.exe & mkvextract from mkvtoolnix, MediaInfo CLI.exe...and maybe the 7z files in the "Encoding" Folder. All x32 bit.

    You can do it in one process using PopcornMKV Audio Converter https://www.videohelp.com/software/PopCorn-MKV-AudioConverter no need to demux or muck about with command line routines. Just load the file in and select what you want. The default settings are TrueHD to DTS

    TrueHD to DTS?

    I only see TrueHD to FLAC.


    I am looking for a program to convert TrueHD 7.1 to DDP 7.1, does anyone know one that is free software?

  6. I don't think there is any free DD+/E-AC3 encoder that supports 7.1.

    Well, do you know with what program I can convert TrueHD 7.1 to DDP 5.1 with 1536kbps?

  8. For example:
    ffmpeg -i "input.thd" -c:a eac3 -b:a 1536k "output.eac3"
    or within a container:
    ffmpeg -i "input.mkv" -map 0 -c:v copy -c:a eac3 -b:a 1536k -c:s copy "output.mkv"

    I did it with useac3to.
    I wanted to ask you, in case you want to convert TrueHD 7.1 to DDP 5.1 or FLAC.
    Which of these last two would be the best option?

  10. What is your goal?
    Quality-wise FLAC because FLAC is a lossless compression (like TrueHD).
    If you want to balance quality/file size then I would extract the (E-)AC3 core (if your source is a Blu-Ray it should have such a core). That's what I do, personally. I do not hear any difference to TrueHD/FLAC.

    That PopcornMKV Audio Converter looks like it would be useful- the download is a zip file with an exe file. When run, the program says it needs to download the toolkit. When I try to download, nothing happens- a progress bar appears but nothing downloads.
    It seems that the program link is dead. What utilities are needed and how should this be set up on a PC?

    After you install the program there should be a a zip file called AudioConverterTools.ZIP that contains all the helper programs. just create a folder called Tools and put them in that folder. Try this site http://auto-download.com/download/get/IcrAUQqHei/audioconvertertools_zip.html

    Thanks netmask56. I was able to download the tools.
    I do have a problem getting the program to actually convert anything. A window pops up for a second (getting info on the file) and no file appears in the output folder. I'll keep trying when I have time, but I've found that AVIDemux can do audio conversions as well.
    I know this is an old message thread about an old program so ...

    I use it every week without issue but it is slow. It does take sometime for conversion
