=========================================================================== Advanced engine needed : Vanilla Doom required Title : PC speaker sound effect format Filename : speaker.txt Release date : 2007-02-27 Authors : Simon Howard, Andrew Apted Email Address : fraggle@gmail.com, ajapted@users.sourceforge.net Description : Finally the last piece in the puzzle of the Doom WAD format has been solved! While every other lump format contained in the Doom IWADs was long ago reverse engineered, one last mystery remained: the PC speaker sound effects. This is a technical description of the PC speaker file format, determined through reverse engineering the Vanilla Doom executables. Also included is some example code for generating and playing back PC speaker sound effects, and a WAD containing some replacement sound effects. =========================================================================== * Copyright / Permissions * GPL.
