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 ... Read more
