I'd like to add a voice to the video.
I'd like to add additional updates to the existing audio.
Speak easily ..
With traditional music.I want to have my voice eumseong.
I have an audio file that I made earlier.
The image has background music.
Together with these two things simultaneously ...
I want to print it at the same time.
Is there any way?

Two audio pieces ...
One, I'd like to make it.

I would like to mix up the sounds.(In the video ...)
The background is ...
And my voice ...


I want to add a function.
A new feature.

MKVToolnix has no encoding abilities, it's sole purpose is to build and manage Matroska headers and elements.

The matroska format has no ability to script mixing commands to be carried out on playback either, that's something only Blu Ray can do.

You'll need to decode your audio, remix it and re-encode it with a program like FFMPEG or a proper audio editor.
