LibKeyFinder is a musical key chord detection library with high accuracy. Its performance is on par with top commercial solutions available such as MixedInKey or Tonart.

I contributed the following additions to the project:

– extended the initial C++ library to support any programming language
– a first .NET assembly for using the library from C#
– a second .NET assembly that simplifies the usage of it
– NuGet packages: LibKeyFinderDotNet and LibKeyFinderDotNet.BASS

I also plan to make features in KeyFinder application available from these assemblies.
