Hello, how are you, I have a .mkv file with an Atmos track, what is the command to do it? And if you could help me trim the audio without losing the dynamic objects, thank you.

Hi, this tool does not support mkv demuxing, you can make use of some mkv->mp4 converting tools to get the mp4 first, for example, ffmpeg.

Then run the binary file in bin folder, for example in windows command line tool,

./mp4demuxer.exe --input-file input.mp4 --output-folder tmp
