A .caf format file uses 64-bit file offset technology that can save a large number of recorded audio files in different formats and metadata tracks. Apart from audio data, these files store information like text, channel layouts, markers and annotations. Programs like Logic Studio and Soundtrack Pro frequently use CAF format files for additional sound effects and surround sound audio compression.
The MP3 format compression algorithm works through perceptual coding. A technique in which audio artifacts outside the auditory range of the average human, are reduced or 'cancelled out'. The result is a near perfect replication of the original audio sample at a compression ratio of 11 to 1 at 128 kilobits per second. Audio quality can be controlled by such factors as the bit rate, sample rate, among other features. But bits rates being the main determinant of audio quality can be adjusted between the typical range from 128 kb/s to as high as 320kb/s.
