So you want to make some changes/enhancements/contributions to SBaGen, but you are a Windows developer and can't be bothered with trudging through all the Visual Studio nastyness to get it all compiling cleanly, well here is a step by step guide I put together while I was doing it, so you don't have to..

   What is it?   SBaGen is a cross platform Binaural Beat Generator writen by Jim Peters, please follow the link for more information.
Download SBaGen
Download MAD: MPEG Audio Decoder
Download LibOGG
Download LibVorbis

NOTE: If you are building with VS .NET 2003 or VS 2008, chances are that this guide will get you 95% of the way there and you'll just have to tweak a few things..

Create a project directory, and extract the sources from the archives listed above:

Create a new Visuall C++ project for a command line app, call it sbagen_vc and set the location to the project directory you created in step 1, uncheck 'create directory for solution':

After clicking ok, then next, tick the empty project checkbox.
