Apple Lossless (also known as Apple Lossless Encoder, ALE, or Apple Lossless Audio Codec, ALAC) is an audio codec developed by Apple Inc. for lossless data compression of digital music. A filename extension is a suffix to the name of a computer file applied to indicate its type. ... Apple Inc. ... Lossless data compression is a class of data compression algorithms that allows the exact original data to be reconstructed from the compressed data. ... An audio file format is a container format for storing audio data on a computer system. ... For other parts of the MPEG-4 standard, see MPEG-4. ...

Lossless data compression is a class of data compression algorithms that allows the exact original data to be reconstructed from the compressed data. ... For other uses, see Music (disambiguation). ...

Apple Lossless data is stored within an MP4 container with the filename extension .m4a. While Apple Lossless has the same file extension as AAC, it is not a variant of AAC, but uses linear prediction similar to other lossless codecs such as FLAC and Shorten.^[1] iPods with a dock connector (not the Shuffle) and recent firmware can play Apple Lossless-encoded files. It does not utilize any digital rights management (DRM) scheme, but by the nature of the container, it is thought that DRM can be applied to ALAC much the same way it can with other files in QuickTime containers. MPEG-4 Part 14 or *.mp4, is a file format (a so called container) specified as a part of the ISO/ IEC MPEG-4 international standard. ...

Digital rights management (DRM) is an umbrella term that refers to access control technologies used by publishers and copyright holders to limit usage of digital media or devices. ... A container format is a computer file format that can contain various types of data, compressed by means of standardized codecs. ...

Apple claims that audio files compressed with its lossless codec will use up "about half the storage space" that the uncompressed data would require. Testers using a selection of music have found that compressed files are about 40% to 60% the size of the originals depending on the kind of music, similar to other lossless formats. Furthermore, the speed at which it can be decoded makes it useful for a limited-power device such as the iPod.^[2] iPod is a brand of portable media players designed and marketed by Apple Inc. ...

The Apple Lossless Encoder was introduced as a component of QuickTime 6.5.1 on April 28, 2004 and thus as a feature of iTunes 4.5. The codec is also used in the AirPort Express's AirTunes implementation.
