Information about MKV and AAC file formats

🔸 File format MKV AAC
🔸 Full name MKV - Matroska AAC - Advanced Audio Coding
🔸 File extension .mkv, .mk3d, .mka, .mks .aac
🔸 MIME type video/x-matroska, audio/x-matroska audio/aac

🔸 Type of format Container format Audio compression format
🔸 Description The Matroska Multimedia Container is an open standard free container format, a file format that can hold an unlimited number of video, audio, picture, or subtitle tracks in one file. It is intended to serve as a universal format for storing common multimedia content, like movies or TV shows. Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates. ISO and IEC have standardized AAC as part of the MPEG-2 and MPEG-4 specifications.
🔸 Technical details Matroska is similar in concept to other containers like AVI, MP4, or Advanced Systems Format (ASF) but is entirely open in specification, with implementations consisting mostly of open-source software. AAC supports the inclusion of 48 full-bandwidth audio channels in one stream plus 16 low-frequency effects channels, up to 16 "coupling" or dialog channels, and up to 16 data streams. The quality for stereo is satisfactory to modest requirements at 96 kbit/s in joint stereo mode; however, hi-fi transparency demands data rates of at least 128 kbit/s.
