CAF - Core Audio Format

Total Audio MP3 Converter is a professional CAF Converter that converts common audio and video files to CAF format. The software also combine multiple files to one single CAF. Total Audio MP3 Converter supports multiple codecs for CAF file.

PCM 8-bit
PCM 16-bit
PCM 24-bit
PCM 32-bit
PCM 32-bit (float)
PCM 64-bit (float)
IMA ADPCM (4-bit)
GSM

The software supports batch conversion and, is full compatible with 32-bit and 64-bit editions of Vista and Windows 7.

Apple's Core Audio Format is a flexible, state-of-the-art file format for storing and manipulating digital audio data. It is fully supported by Core Audio APIs on Mac OS X v10.4 and later and on Mac OS X v10.3 with QuickTime 7 or later. CAF provides high performance and flexibility, and is scalable to future ultra-high resolution audio recording, editing, and playback.

Core Audio Format is designed to overcome limitations of older digital audio formats, including AIFF and WAV. Just like the QuickTime .mov container, a .caf container can contain many different audio formats, metadata tracks, and much more data. Not limited to a 4 GB file size like older digital audio formats, a single .caf file can theoretically save hundreds of years of recorded audio due to its use of 64-bit file offsets.

CAF files have several advantages over other standard audio file formats:

Unrestricted file size

Whereas AIFF, AIFF-C, and WAV files are limited in size to 4 gigabytes, which might represent as little as 15 minutes of audio, CAF files use 64-bit file offsets, eliminating practical limits. A standard CAF file can hold audio data with a playback duration of hundreds of years.

Safe and efficient recording

Applications writing AIFF and WAV files must either update the data header¡¯s size field at the end of recording¡ªwhich can result in an unusable file if recording is interrupted before the header is finalized¡ªor they must update the size field after recording each packet of data, which is inefficient. With CAF files, in contrast, an application can append new audio data to the end of the file in a manner that allows it to determine the amount of data even if the size field in the header has not been finalized.

Support for many data formats

CAF files serve as wrappers for a wide variety of audio data formats. The flexibility of the CAF file structure and the many types of metadata that can be recorded enable CAF files to be used with practically any type of audio data. Furthermore, CAF files can store any number of audio channels.

Support for many types of auxiliary data

In addition to audio data, CAF files can store text annotations, markers, channel layouts, and many other types of information that can help in the interpretation, analysis, or editing of the audio.

Support for data dependencies

Certain metadata in CAF files is linked to the audio data by an edit count value. You can use this value to determine when metadata has a dependency on the audio data and, furthermore, when the audio data has changed since the metadata was written.
