.mka File — Matroska Audio

MKA is the audio-only variant of the Matroska multimedia container format. MKA files can contain audio encoded with virtually any codec — FLAC, AAC, Vorbis, Opus, MP3, AC3, DTS, PCM, and many others — in a single, flexible container. Matroska's strength lies in its extensibility and rich feature set: MKA supports multiple audio tracks (useful for different languages or commentary tracks), chapters, tags with comprehensive metadata, embedded album art, and lyrics. The container uses the EBML (Extensible Binary Meta Language) structure, which is efficient and forward-compatible. MKA is less common than MKV for video, but it's used when audio content needs features beyond what simpler containers provide — for example, embedding multiple codec tracks in one file, storing lossless audio with chapter markers for classical music, or packaging audiobooks with chapter navigation. The Matroska format is open and maintained by the Matroska.org community. While not as universally supported as MP3 or M4A, MKA is handled by most modern media players including VLC, mpv, and foobar2000.
