PC speaker
From Chocolate Doom
Chocolate Doom pioneered PC speaker support within Doom source ports, and remains one of the few ports to support the use of PC speaker sound effects.
The format of PC speaker sound files was reverse engineered and the details published (http://www.doomworld.com/idgames/index.php?id=14832) as part of the development of this feature. Before this, PC speaker sound effects remained one of the last remaining unknown lump formats in Doom WAD files.
Backends for "native" PC speaker playback (through the real PC speaker) exist for Linux and the BSDs. On other systems, the PC speaker can be emulated through the digital sound output.
