It does not utilize any 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.

	Apple claims that audio files compressed with its lossless codec will use up ''"about half the storage space"'' that the uncompressed data would require.
