MKA (.mka)
.mka file signature | audio/matroska
Matroska Audio (MKA) is a multimedia container format developed and maintained by the Matroska project. It is used to store audio tracks, sometimes with chapters, metadata, and subtitles, for music albums, audiobooks, and archived media. Like other container formats, it can carry multiple embedded streams and metadata, but the format itself is generally considered safe; any risk usually depends on the media player and the content stored within it.

It is used to store audio tracks, sometimes with chapters, metadata, and subtitles, for music albums, audiobooks, and archived media. Like other container formats, it can carry multiple embedded streams and metadata, but the format itself is generally considered safe; any risk usually depends on the media player and the content stored within it.
What are the magic bytes for .mka files?
The magic bytes for MKA files are 1A 45 DF A3 at byte offset 0. These bytes uniquely identify the file format regardless of the file extension.
How do I validate a .mka file?
To validate a .mka file, read the first bytes of the file and compare them against the known magic bytes (1A 45 DF A3) at offset 0. This is more reliable than checking the file extension alone, as extensions can be renamed.
What is the MIME type for .mka files?
The primary MIME type for .mka files is audio/matroska.
Is it safe to open .mka files?
MKA (.mka) files are generally safe to open. They are classified as low risk because they primarily contain data rather than executable code. However, always ensure files come from a trusted source.
