What is a .NAAC file?
A .NAAC file is a type of audio file that is used in some video games made for the Nintendo 3DS, a handheld gaming console. These games are created by a company called Namco. Some examples of games that use .NAAC files include "Ace Combat: Assault Horizon Legacy" and "Taiko no Tatsujin: Don to Katsu no Jikuu Daibouken." These files usually have music that you can hear while playing the game.
To open a .NAAC file, you can use a program called vgmstream, which is available in different versions. You can also use Foobar2000 or Nullsoft Winamp, but you need to add a special vgmstream plug-in to these programs to make them work with .NAAC files. There's also a web version of vgmstream that lets you open these files online.
.NAAC files are actually a special kind of .AAC file, which stands for Advanced Audio Coding. It's a format used to store high-quality audio. What makes .NAAC files special is that they have a unique part at the beginning of the file (called a file header) that is specific to Namco games. This means that while the audio part of the file is standard, the way it's packaged is unique to Namco.
People who like to modify games or are just curious about how games are made might come across .NAAC files when they are looking through the files of a Namco game for the Nintendo 3DS. For example, if they are looking in the folder where the game keeps its music, they might find .NAAC files.
