AIFF Technical Specifications

File extension	.aiff
File category	Audio
Stands for	Audio Interchange File Format
Developer	Apple Inc.
Overview	AIFF is an uncompressed audio file format. It keeps the original file without losing any data. This is the main reason why these files require more storage space. One minute-long audio requires nearly 10MB space. It is widely used by Apple Macintosh/Apple Mac and also musicians use this format for their recordings. Exact copies of music can be formed using this format with the added benefit of sound quality, which is well maintained in these files. Though it follows lossless format(not compressed), yet, there is another variant of it named AIFF-C developed by Apple afterwards and it is the compressed version. The only disadvantage of these files is a large size.
Technical description	Mostly AIFF files have uncompressed Pulse Code Modulation(PCM) data which means at regular intervals the amplitude of the analog signal is reduced from continuous-time signal to a discrete-time signal and every sample is quantized to the closest value. An AFF file has various parts which are known as chunks and each chunk has its own ID which is mostly termed as FourCC. This ID is a sequel of four bytes which distinctly identify data formats. The several chunks found in this format are Common, Sound data, Marker, Instrument, Comment, Name, Author, Copyright, Annotation, Audio recording, MIDI data, Application, and ID3. The first two chunks are essential every time(Common chunk and Sound data Chunk). Lastly, these files have the capability of storing Metadata in five chunks-Name, author, comment, annotation and copyright. Metadata delivers information about the data that is data about data.

MKV Technical Specifications

File category	Video
Stands for	Matroska Multimedia Container
Developer	Steve Lhomme
Overview	An unlimited amount of data such as an infinite number of audios, videos, pictures, arbitrary files like XML and subtitle tracks can be stored in MKV files. Although, it has a similar concept that of AVI, MP4; etc., yet, there is one difference. It is an open-source software or has open specifications, whereas, others are different. Furthermore, it allows online streaming and fast seeking which are alluring features. It can be used with ease as it is highly adaptive and can accept any audio and video.
Technical description	Files in MKV format store each track in varied dataline. Files in this format use distinctive extensions for storing the data. The extension .MKV is used only for video files(may have subtitles and audio),.MK3D for stereoscopic video, .MKA and .MKS for audio and subtitles respectively. The codecs that are linked to this format are .SRT, Vobsub, .USF(Universal Subtitle Format) and .SSA; etc. It should be noted that not all the media players support this file format but only selective ones like VLC. Besides this, ‘Matroska' is derived from a Russian word that is ‘Matryoshka’ and it refers to a hollow Russian doll which opens to uncover another doll, this doll then again opens to reveal next doll and the process goes on. Other meanings for this word in Russia are a sailor suit and a female sailor. Technical details in depth are available only for private and commercial use.
