Hi all, I need a class library file in .NET which would be used in C# WPF Desktop application to add feature to be able to record audio being streamed from speakers. The solution should be able to distinguish between output device, speaker, and input device, microphone, and be able to record sound uniquely and if possible simultaneously. It should work on both 32-bit and 64-bit architecture as the application is targeted for same. Thanks for your time.
