Description MKV Matroska is an open source multimedia container format that supports more than one audio and subtitle tracks at the same file. It is the most convenient of file types where you can add a large sum of data, such as videos, audios, texts, and various images. It is basically a RAW format which you can later flip and separate on the basis of needed data tracks.
Technical details Every file whether it is video, audio, subtitle or image it will be stored into a separate data line. It is a lot similar to the MP4 or AVI format although when users are packaging an MKV file they rarely bundle all the tracks within the file. Various media players don't even support the MKV video format therefore, the users need to use specialized media players who can support the MKV format such as VLC media player.

File extension .flac
File category audio
Description

A free codec developed for lossless compression of audio content that does not exclude information from the stream. It allows for listening to musical compositions with professional sound reproduction systems, as well as for track archiving. FLAC files are being played by portative audio players, supplied by the most of specialized programs, and are represented in huge variety of hardware implementations. They allow users to copy CD tracks without deterioration in sound quality.

Technical details

Since streaming is being coded with an increased speed, FLAC files are often less than half of the original track. However, this does not affect the track quality, and therefore the format is popular for online translations and real-time coding. FLAC can support samples with a static point within the range of 4-32 bit per sample and sampling frequency of 655.3 KHz. If new fields arrive, decoders are not being affected.

In order to change FLAC format, one may use Sound Forge or Adobe Audition. In addition to that, some smartphones can easily work with such files.
