Those are the good old PC-speaker sounds for your advanced DOOM port..
For nostalgical reasons, try them out (remember when you lost your
mind facing your first IMP)..

Title                   : SPKSND

Filename                : spksnd.wad
Author                  : CP, an old-fashioned ATARI and MAC user
Email Address           : [email protected]
Misc. Author Info       : Trying to play DOOM for years..
                         (and: MacDOOM doesn't have PC-speaker sound..)

Description             : replaces the original sounds for Doom/Doom 2
                         by the funny old PC-speaker sounds..
                         Nice if you use it on e.g. a Mac
                         (only nice if you started to play DOOM on
                          PCs without sound cards :-) )
