  dcterms:description "Audio Interchange File Format (AIFF) is an uncompressed audio format based on Electronic Arts' Interchange File Format 85 and similar to WAV. AIFF is predominantly used on Apple macOS personal computers and allows for embedded metadata. AIFF was developed in 1988 by Apple and is proprietary, and it is widely adopted in the Apple community. AIFF does not allow for compressed audio data, so the separate AIFF-C (Compressed) format was developed in 1990. Information is not available to indicate how many times the file specification has been updated over the years. Linear Pulse Code Modulated Audio (LPCM) is an uncompressed linear audio signal used for CD and DVDs. LPCM was first used digitally in 1967 by the Japanese Broadcasting Corporation NHK and was first used on a CD in 1982. For this file format, AIFF is the wrapper around the LPCM sound bitstream. This practice is widely used by the Apple community. Open source software is available for transcoding. As the wrapper, AIFF is considered an acceptable format per NARA Transfer Guidance. AIFF files with the LCPM codec should be retained as-is since the files can easily be opened, are lossless, and are prevalent in the field." ;
