| File Description |
Audio file compressed with the Apple Lossless Encoder (ALE); uses the Apple Lossless Audio Codec (ALAC), which provides lossless compression; saved in the MPEG-4 container format.
M4A files are similar to .MP4 video files, but do not contain a video track; MPEG-4 audio files that include copyright protection, such as those sold through the iTunes Store, typically have an .M4P extension. |
