Information about AIFF and M4A file formats

Full name AIFF - Audio Interchange File Format M4A - Audio-only MPEG-4
File extension .aiff, .aif, .aifc .m4a
MIME type audio/x-aiff, audio/aiff video/mp4
Developed by Apple Inc. International Organization for Standardization
Type of format audio file format, container format Media container
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. MPEG-4 Part 14 or MP4 is a digital multimedia container format most commonly used to store video and audio. However, it can also be used to store other data such as subtitles and still images. M4A stands for MPEG 4 Audio and is a filename extension used to represent audio files.
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. Audio-only MPEG-4 files generally have a .m4a extension. This is especially true of non-protected content. M4A is often compressed using AAC encoding (lossy) but can also be in Apple Lossless format.
