    "BasicInformation": "M4A文件是使用高级音频编码（AAC）或苹果无损音频编解码器（ALAC）编码的 MPEG-4 音频文件。它可能包含各种音频文件，包括歌曲，播客和有声读物。",
    "DetailedInformation": "MPEG-4 是一种用于压缩音频和视频数据的多媒体容器格式。存储音频和视频数据的.MP4 文件使用此格式。.m4a 后缀代表 “MPEG-4 音频”，是因为 M4A 文件专门携带音频数据而创建的。这一命名更改使人们更容易区分 MPEG-4 视频文件和 MPEG-4 纯音频文件之间的区别。与其他音频文件类型一样，有一个有损压缩选项，它是使用AAC编码实现的。Apple无损格式允许无损压缩，这在其他音频格式中是无法实现的。",
