What is a m4a file and how do I open a m4a file?
M4A files are commonly known as MPEG-4 audio files, and these .m4a files contain digital audio data that has been implemented with AAC compression standards or ALAC (Apple Lossless Audio Codec) specifications. The M4A file format was developed by Apple in order for users to not have any difficulty in distinguishing MP4 files that contain audio and video content from MP4 files that only contain audio data. These M4A files are mostly used for storing audio book content and digital music, and the Apple iTunes Store offers many selections in M4A format. Most of the M4A audio books and digital music tracks that can be downloaded from the Apple iTunes Store are integrated with AAC compression, thereby significantly reducing the size of these .m4a files.
