Information about AIFF and FLAC file formats

Full name AIFF - Audio Interchange File Format FLAC - Free Lossless Audio Codec
File extension .aiff, .aif, .aifc .flac
MIME type audio/x-aiff, audio/aiff audio/x-flac

Type of format audio file format, container format Audio
Description Audio Interchange File Format (AIFF) is an audio file format standard used for storing sound data for personal computers and other electronic audio devices. The format was developed by Apple Inc. in 1988 based on Electronic Arts' Interchange File Format (IFF, widely used on Amiga systems) and is most commonly used on Apple Macintosh computer systems. FLAC (Free Lossless Audio Codec) is an audio coding format for lossless compression of digital audio and is also the name of the reference codec implementation. Digital audio compressed by FLAC's algorithm can typically be reduced to 50-60% of its original size and decompress to an identical copy of the original audio data.
Technical details The audio data in most AIFF files is uncompressed pulse-code modulation (PCM). This type of AIFF file uses much more disk space than lossy formats like MP3—about 10 MB for one minute of stereo audio at a sample rate of 44.1 kHz and a bit depth of 16 bits. There is also a compressed variant of AIFF known as AIFF-C or AIFC, with variously defined compression codecs. The technical strengths of FLAC compared to other lossless formats lie in its ability to be streamed and decoded quickly, independent of compression level. Compared to compressed audio formats, FFmpeg's FLAC implementation was noted to have the fastest and most efficient embedded decoder of any modern lossless audio format.
