Identification and description Explanation of format description terms

Full name Matroska File Format with MP3 Audio Encoding
Description

Matroska file containing an audio essence encoded as MP3.

On the Matroska FAQ page (consulted November 13, 2013), the developers suggest reasons for wrapping MP3 encoding in Matroska. For example, they state that lyrics or transcriptions can be embedded in the audio file, that one may use chapters to separate parts of a track or a live album, adding that in some cases (MP3, AC3, DTS) "the Matroska file may also be smaller than the original with much better/cleaner seeking support." Regarding sources for captions or subtitles, the FAQ mentions the example of srt subtitle files, a format associated with the SubRip software application.
