What is a BWAV file?
A BWAV file is an audio file used by various Nintendo Wii video games, including Mario Kart Wii. It contains in-game sound effects or music saved in the Binary Wave (BWAV) format. BWAV files typically consist of a file header, channel information, and channel samples.
BWAV is one of many proprietary file formats Nintendo utilizes to store in-game audio. You will most likely only encounter the file format if you dump a Wii game to a computer to play it with emulation software or modify the game.
The BWAV file format includes the following sections:
- File Header - Contains information about data stored in the file including the version and number of channels in the file.
- Channel Info - Contains information about how the game should play the audio in specific channels.
- Channel Samples - Contains audio data encoded with DSP-ADPCM encoding, a codec commonly utilized in Wii, Wii U, and GameCube systems.
How do I open a BWAV file?
BWAV files are not meant to be opened. Instead, they are referenced by the game they are packaged with to play audio during gameplay.
However, if you are looking to modify BWAV files, you can use Citric Composer in Windows. Or you can use a hex editor, such as HxD or HHD Software Free Hex Editor Neo.
