WebRtcVad type
WebRtcVadSharp
A .NET adapter for WebRTC's voice activity detection library.
Because the underlying WebRTC library has robust (and fast) error checking of its own, this class primarily validates input arguments the raw WebRTC calls have failed to provide specific information about what went wrong. This approach avoids costly enum conversions/validations until a failure state obtains, at which point performance presumably doesn't matter.
