Apple Lossless (also known as Apple Lossless Encoder, ALE, or Apple Lossless Audio Codec, ALAC) is a lossless audio codec developed by Apple Inc. Apple Lossless is not a variant of AAC, which apple also uses for music downloads, but is similar in design to FLAC. All current iPod players can play Apple Lossless-encoded files.
Audio files compressed with the Apple Lossless codec will be about 40% to 60% the size of the originals depending on the kind of music, similar to other lossless but compressed file formats. Furthermore, the speed at which it can be decoded makes it useful for a limited-power device such as the iPod.
