What is a BCWAV file?

A BCWAV file is an audio file used by a Nintendo 3DS video game. It is saved in a proprietary version of the .WAV format, used only by 3DS games. However, modders have created utilities that allow them to play and convert the audio that BCWAV files contain.

More Information

Binary CTR Wave, or BCWAV, files contain sound effects or music played in a Nintendo 3DS video game. For example, the game Fire Emblem Fates contains many BCWAV files used to play in-game sounds.

BCWAV files are stored in .BCSAR audio archives, located in a 3DS cartridge's romfs/​sound directory. While most gamers will never encounter a game's BCWAV files, 3DS modders regularly extract, modify, play, and replace BCWAV files, to customize 3DS games.

How to convert a BCWAV file

You can use Foobar2000 with the vgmstream plug-in installed to convert BCWAV files to .WAV and other common audio formats.
