  1. Hello,
    I have various mkv files that I would like to reprocess audio to add DRC to work better for on my system. Ideally I would could even want this compressed audio added as a new stream so I could change between them depending on location I want to watch video. Does anyone have a recipe for this?

    What's wrong with DRC on your system?

    Don't know a CLI way to do this, I got tired of using the terminal 30 years ago. But you could import the file into Audacity (which will import just the audio stream of video files) and apply compression/normalization filters however you want. Then open the video file in Avidemux, set both audio and video streams to Copy, and import the audio file you created with Audacity. I suggest Audacity because it's simple and many video editor/converters won't do direct stream copy.

  4. Then the compat-function in sox (http://sox.sourceforge.net/sox.html) or ffmpegs dynaudnorm-option might be what you want.
