Voice Activity Detection in Elixir with Membran

I hacked on something quite useful in the last few weeks, off and on. Voice Activity Detection in Elixir with Silero VAD through ONNX. I'll show what I did and try to give an idea of what it is and why it is useful.

More importantly we only need to send the chunks that seem voice-like on for processing or only transmit those to a listener on the other side. My goal with this was actually to use it in The Grand Kiosk a Nerves demo for the Seeed Studio ReTerminal DM that I am working on. I was happy to see that once I got the right data shape into Silero VAD all my previous experience with Membrane elements made those parts just slot together quite nicely.
