About the formats
Audio file formats
AC3 files represent the Dolby Digital audio codec, which can include up to 6 audio channels (DD 5.1 surround sound with subwoofer output). Such files are often used for cinemas, DVDs, and game consoles.
Audio file formats
M4A files store audio using the AAC codec. M4A stands for MPEG-4 Audio. It is very similar to MP4 with the difference being the lack of a video/subtitle track in the file.
