About MKA files
MKA (Matroska Audio) is an audio container format based on the Matroska multimedia framework. It supports various audio codecs (e.g., FLAC, AAC, Opus) and features like multiple audio tracks, chapters, and metadata. Primarily used for high-quality audio storage and playback, it offers flexibility similar to MKV but focuses solely on audio content.
