Paranormal Equipment Project - Live EVP recordings and white noise isolation

I recently saw online some projects that people have built using various pieces of equipment for the purpose of isolating noise and allowing for live EVP recording and witnessing in the moment. These projects are verifiable, tested, and proven pieces of paranormal investigative equipment, but they take time and money to assemble. I am currently planning to assemble such a device myself, using the same proven components that others before me have made, in order to streamline EVP recording and interactions while on cases. 

This will greatly cut down the number of hours spent sifting through audio, isolating white noise, and scrubbing for evidence, and provide in-the-moment analysis, and evidence for clients, as well as save my ears (to a degree!). Of course I'll still have to scrub through microphone recordings regardless, but this will greatly reduce turn-around time for clients and improve results ten-fold!

More on this project to come in future~!
Keep your eyes peeled because it will happen in the next month or so at least!
