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.

AAC files are audio files using Advanced Audio Coding compression. AAC is a lossy format, meaning the audio quality remains almost the same as the original source. The slight loss leads to the audio files taking up less space, which makes them ideal for music streaming or when bandwidth is limited. AAC is superior to MP3 for handling frequencies above 16 kHz. The encoding efficiency for transient and stationary signals is also better when compared to MP3.
