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.

Overview

It is a multimedia container file format which is used over the internet to provide digital video content to the users. Digital video content includes TV shows or series, movies; etc. Adobe Flash Player 6 and new versions provide support to it. To play flash video from Personal Computer and online websites we need an FLV player. Although, Apple iOS does not support Flash, yet, with the help of additional software, one can play flash videos. Also, it is a common platform for various websites that allows video streaming such as YouTube, Yahoo! Video, Metacafe, Hulu; etc . With the help of screen capturing and other recording programs, screen recording is possible for flash videos. Furthermore, it also supports a screen share or screen cast.

Technical description

FLV files mostly have video bitstreams which are one of the variants of H.263 Standard and it is named as Sorenson park(FourCC FLV1). The SWF files and this extension uses the identical way to encode data. There are two variants available for screen casting. First one is lossy as it reduces colour depth or bit depth (number of bits used to indicate the colour of one pixel) and compresses the data. The second type is only compatible with Flash Player 8 and the newer versions. Both these aforesaid kinds are based on bitmap tile. Uncompressed Audio or ADPCM format audio is also supported by it. This format has header and packets in its video structure. A standard header includes signature, version, flags and header size.
