Nintendo DSi Sound is an sound application built into the Nintendo DSi to play and play WITH music files in the AAC format and utilizes its microphone.


Nintendo DSi Sound is an application that ship with the Nintendo DSi. With it, you can listen and "play with" AAC audio files stored on a memory card. You can also record and edit your own voice. It can't play MP3 audio files. The sound application can also browse through folders that you store your music in. For instance, you can make a folder on the SD card that is named "Country" and put all of your country music in it and when you are looking for music on the channel you will see the folder "Country" and be able to see all of the music, and play, all the music that has been put in it. This can help you organize your music if you have a lot of it on the SD card. Note that there is a 3,000 song display limit on the Nintendo DSi.
