This is an integration of the [node-vad](https://github.com/Snirpo/node-vad) implementation of webrtc vad.  
This node allows you to perform voice activity detection on pcm audio buffers.  
Simply send a stream of buffers through this node and it will attach a message property to each message stating if the buffer in that message had voice in it or not.  
This can for example be used in conjunction with a microphone stream and a speech to text node to only send audio containing speech to be transcribed.  
It can also be used to build a effective voice command recorder used together with a microphone node to determine when the command was finished.

As always im happy about feedback, feature requests and bug reports on the nodes repo:
