The MKA file type is primarily associated with 'Matroska' by Matroska Association. The Matroska multimedia container formats were derived from a project called MCF, but differ from it significantly because it is based on EBML (Extensible Binary Meta Language), a binary derivative of XML. EBML enables future format extensibility, without breaking file support in old parsers. This is a container, not a CODEC. Get the parser from the Matroska site. MKA files are typical matroska files containing only audio information, but no video. These files may typically comprise a complete music album in one single file, where file chapters mark each song. In addition to that the file can have attachement like lyrics or cover JPEGs, or even show a Karaoke subtitle stream.
