The kxsfc file extension is associated with the kX Project, an alternative hardware driver for Sound Blaster Live and Sound Blaster Audigy sound cards.
A kxsfc file is a project-specific SoundFont collection. It is intended to be managed by the kX Project software rather than used as a standalone audio recording.
The format is intended for Microsoft Windows, which is the platform supported by the kX Project software.
Open a kxsfc file in the kX Project software on Microsoft Windows. The file is intended to be accessed through the software's SoundFont collection features, and is not normally opened by a media player.
A kxsfc file is a SoundFont collection rather than a conventional audio file, so it has no usual audio conversion path. Use the kX Project software to manage the collection. Conversion of individual SoundFont files requires software that supports those files.
