About the formats
Audio/Music file formats
MPEG (Moving Picture Experts Group)
MP3 is a commonly used audio format. The audio data is compressed inside the file, which is why MP3 files take up less space than WAV, for example. Even though the audio is compressed, the quality is still good enough for most personal use cases.
Audio/Music 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.
