What is a .fsb file?
File extension details and usage information
An FSB (FMOD Sample Bank) file is a proprietary audio container format developed by Firelight Technologies for use with their FMOD audio engine. It is widely used in the video game industry to store sound effects, music tracks, and voiceovers in a compressed and organized manner. FSB files can package multiple audio samples into a single file, often using various compression codecs like ADPCM, MP3, Vorbis, or FAD (FMOD Audio Decoder) depending on the target platform's hardware capabilities. This format allows game developers to manage audio assets efficiently, reduce disk space, and optimize memory usage during gameplay. Because it is a proprietary container, playing or extracting FSB files typically requires specialized tools or game modding utilities rather than standard media players.
