    Hi,

    up to now I've been doing this with audiacity: demuxing from TS, loading AC3 into audiacity, manually selecting begining of audio, applying Fade In, then selecting end of audio and applying Fade Out. Finally exporting as AC-3

    Now I would like to add some automatisation to this process.
    Is there a cmd program which can help ?

    Thanks

  2. sox should be able to do the decoding and fading (you will have to read the documentation, but that's a given for command line tools) and than ffmpeg or aften could be used for reencoding to ac3.

    Audio subforum would have been a better place, but some moderator will probably move it.

    thanks for answering.

    Looks like sox doesn't recognise AC3 but I can change it into WAV with eac3to and then make a fade with sox. Last thing is to change back to ac3 (again eac3to) - this workflow is working.

    Thanks again Selur

    than it's probably build without ffmpeg support libraries, but using eac3to is also fine.
