Information about MP3 and CAF file formats

Name MP3 CAF
Full name MP3 - MPEG-1 or MPEG-2 Audio Layer III Core Audio Format
File extension .mp3 .caf
MIME type audio/mpeg, audio/MPA, audio/mpa-robust audio/x-caf
Developed by Fraunhofer Institute Apple Inc
Type of format Digital audio Music File
Description MPEG-1 or MPEG-2 Audio Layer III, more commonly referred to as MP3, is an audio coding format for digital audio that uses lossy data compression. It is a common audio format for consumer audio streaming or storage and a de facto standard of digital audio compression for the transfer and playback of music on most digital audio players. 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 several advantages over other standard audio file formats: available file size, safe and efficient recording, support for many data formats, and data dependencies. The Core Audio Format was essentially developed to free audio files of the limitations of older formats.
Technical details Lossy compression is designed to reduce significantly the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio. For example, an MP3 file created using the setting of 128 kbit/s will result in a file about 1/11 the size of the CD file created from the original audio source. CAF files use 64-bit file offsets, freeing them from the file size limitations of older formats. CAF files begin with a file header used to determine the file type and CAF version. A series of chunks then follow this. The only types of chunk data required for CAF files are the 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.
