NOTE: This solution will require Telerik RadForms. However, it can be easily converted back to winforms. Other changes made were converting 'int' to 'int32', a bug in the audiogram which caused crashing, and also updated to C#7/.NET 4.6. Solution will compile for both x32/x64bit builds, changed a few colors. Added autochecking for x32/x64 PortAudio and EXT_IO. You can place both verions in the same folder without conflicts. I prefer this over SDRSharp. Nice!
