The MKA format
MKA is audio tracks in a Matroska container. MKA is the audio-only form of the 2002 Matroska container, often used to ship a film’s extra language tracks.
When to use MKA
Convert MKA to MP3, M4A or FLAC to play it outside media-center software.
It is best for separate soundtracks and language dubs that sit next to an MKV, and it opens on VLC, mpv, Plex and Kodi.
How to open it: VLC, mpv and Plex play MKA files.
