How to Play Multiple Audio Tracks Simultaneously

[zeromeia0]

I'm new to MPV, and I've been having issue dealing with one problem. I downloaded MPV because I saw somewhere that it can play multiple audio tracks at the same time, but I had to use scripts. Here are the ones I found

• .\mpv.exe --lavfi-complex="[aid1][aid2][aid3]amix=inputs=3[ao]" "video.mp4" | #Source
• mpv "C:\File Path\First Video" | mpv "C:\File Path\Second Video" #Source

I also found theese 2 discussions about it:
#10554
#6536

But I have no idea what they meant.

My pc has dual boot with Windows 10 and Ubuntu 10.04. On both OS, how do I create the script, where do I put it and what else do I need to in order to listen to multiple audio tracks at the same time?

--lavfi-complex="[aid1][aid2][aid3]amix=inputs=3[ao]" should already work as long as there are 3 audio tracks.

And where exactly do I find mpv.conf? I downloaded the folder called mpv-x86_64-windows-msvc, and the files I have are mvp.com which opens on cmd, mpv.exe, mpv.pdb and vulkan-1.dll. Should I download another folder or I can just create a folder called mpv.conf?

The file doesn't exist in my PC. Can I create it myself?

[guidocella]

Yes, it's not created by default.
