Sound in MegaZeux/Sound Engines

Bells, Whistles, and Sound Boards (better known as BWSB) is a DOS-based sound library that was popular throughout the demoscene in the mid-1990's. It was programmed by Zilym Limms and supports a small variety of sound cards such as Sound Blaster and Gravis UltraSound. The library has support for most early MOD music formats, and limited support for S3M music (after converting it to GDM format first).

BWSB was the sound library used for MegaZeux for all DOS releases from 2.50 onward (replacing Mark J. Cox's ModObj). It was dropped in favor of ModPlug and MikMod (and eventually libxmp) for the SDL port.
