FamiStudio uses some external libraries for sound emulation, import and export to various formats. Many thanks to the developers working on these.


Great little NES sound emulation library created by Blargg. It also includes improvements they made later on in Game_Music_Emu. Was also modified by me to add a few more expansions.


Originally a Winamp plugin to play NSF created by Disch, it was stripped down to only keep the audio emulation core and is used for the NSF import.


Small library that emulates the YM2149 chip (aka PSG), created by by Mitsutaka Okazaki. It is used for the EPSM emulation.


Very similar to emu2149 and also created by Mitsutaka Okazaki, but used for the VRC7 emulation.


OPN2 is a high-accuracy YM3438 emulator. FamiStudio uses a slightly modified version of this library from BambooTracker for EPSM emulation.


Created by Gabriel Bouvigne, Pete Everett, Patrick Roberts and others. Used for the MP3 export.


Created by the Xiph.Org Foundation. Used for the OGG/Vorbis export.


GifDec is a tiny little C library to read animated GIF files. It does one thing and does it very well. It is used to display the tutorials on all platforms.


GLFW is a very simple windowing & input management system for OpenGL. It is used by all 3 platforms on Desktop for the main FamiStudio window. The C# bindings are provided by GLFWDotNet.


Stb is a fantastic, pure-C, single-file library that does a bunch of low-level things that are useful for game development. FamiStudio uses their True-Type font rasterization and rectangle packing code for its text rendering.

A few demo songs are also provided with FamiStudio. Unless mentioned, the demo songs are my re-creations, done by reverse-engineering the NSF. Many thanks to the contributors.
