 AdPlug is a free, cross-platform, hardware independent AdLib sound player library, mainly written in C++ and released under the LGPL.
 AdPlug plays sound data, originally created for the AdLib (OPL2) audio board, directly from its original format on top of an OPL2 emulator or by using the real hardware.
 No OPL chip is required for playback.
