cppSfxr, a PSG C++ library

cppSfxr is a compact Procedural Sound Generation (PSG) library in c++ with both a C dll wrapper to provide modular loading, and an luajit FFI wrapper around that to allow it's use in the LÖVE game engine. The core sound generation engine was originally written by DrPetter for the 10th Ludum Dare competition.

It is purely a sound generation library, and has no connections to any audio rendering engines or systems. The advantage of this is that it is easily compiled anywhere little endian systems allow. A precompiled dynamic link library is provided for the following platforms (in th dll folder):

• Windows: x64cppSfxr.dll, compiled with MSVC, for any Intel AMD64 machine
• Mac OS X: x64cppSfxr.dylib, compiled with gcc/clang via brew, for Intel macs.
• Mac OS X (M1): m1cppSfxr.dylib, compiled with gcc/clang via brew, for new Apple Silicon macs.
• Debian: x64cppSfxr.so, compiled with gcc, for any Intel AMD64 machine.

While not provided prebuilt, it is also trivial to compile into a small static library you can link into your application. The code has been compiled against iso:std++17 standard.
