Apple has released its Apple Lossless Audio Codec (ALAC) as an open-source project.
Debuted in 2004, ALAC is “a data compression method which reduces the size of audio files with no loss of information. A decoded ALAC stream is bit-for-bit identical to the original uncompressed audio file.” The project, released yesterday, contains the sources for the ALAC encoder and decoder, an example command line utility, and a description of a “magic cookie” for use based on the ISO case media file format.
The Apple Lossless Audio Codec sources are available under the Apache license.
