Information about AAC and CAF file formats
|Full name||AAC - Advanced Audio Coding||Core Audio Format|
|Developed by||Bell Labs, Fraunhofer Institute etc.||Apple Inc|
|Type of format||Audio compression format||Music File|
|Description||Advanced Audio Coding (AAC) is an audio coding standard for lossy digital audio compression. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at similar bit rates. AAC has been standardized by ISO and IEC, as part of the MPEG-2 and MPEG-4 specifications.||The Core Audio Format is a container for storing and manipulating digital audio data. CAF provides high performance and flexibility and is scalable to future high resolution audio recording, editing, and playback. CAF files have a number of advantages over other standard audio file formats: Unrestricted file size, Safe and efficient recording, Support for many data formats, Support for data dependencies. The Core Audio Format was essentially developed to free audio files of the limitations of older formats.|
|Technical details||AAC supports inclusion of 48 full-bandwidth audio channels in one stream plus 16 low frequency effects channels, up to 16 "coupling" or dialog channels, and up to 16 data streams. The quality for stereo is satisfactory to modest requirements at 96 kbit/s in joint stereo mode; however, hi-fi transparency demands data rates of at least 128 kbit/s.||CAF files use 64-bit file offsets, freeing it from the file size limitations of older formats. CAF files begin with a file header which is used to determine the file type and CAF version, this is then followed by a series of chunks. The only types of chunk data required for CAF files are Audio data chunk and the Audio description chunk, audio is stored in the audio data chunk and the various pieces of metadata are stored in the Audio Description chunk.|
