Stands for "Moving Picture Experts Group." MPEG is an organization that develops standards for encoding digital audio and video. It works with the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) to ensure media compression standards are widely adopted and universally available.
The MPEG organization has produced a number of digital media standards since its inception in 1998. Examples include:
MPEG-1 – Audio/video standards designed for digital storage media (such as an MP3 file)MPEG-2 – Standards for digital television and DVD videoMPEG-4 – Multimedia standards for the computers, mobile devices, and the webMPEG-7 – ...
Compression, or "data compression," is used to reduce the size of one or more files. When a file is compressed, it takes up less disk space than an uncompressed version and can be transferred to other systems more quickly. Therefore, compression is often used to save disk space and reduce the time needed to transfer files over the Internet.
There are two primary types of data compression:
File CompressionMedia Compression
File compression can be used to compress all types of data into a compressed archive. These ...
Stands for "Audio Interchange File Format." AIFF is a file format designed to store audio data. It was developed by Apple Computer, but is based on Electronic Arts' IFF (Interchange File Format), a container format originally used on Amiga systems.
A standard AIFF file contains 2 channels of uncompressed stereo audio with a sample size of 16 bits, recorded at a sampling rate of 44.1 kilohertz. This is also known as "CD-quality audio," since CDs use the same audio specifications. AIFF audio takes up just over 10MB per ...
