The Matroska Audio (MKA) file is an open standard audio container format maintained by the Matroska non-profit association. This flexible format supports multiple audio streams, chapters, and subtitle tracks in a single file, typically utilized for storing complete music albums or high-quality vocal recordings. Derived from Extensible Binary Meta Language (EBML), MKA files are inherently safe containers that focus on universal interoperability without the licensing restrictions common to proprietary formats.
