EVP'S Live White Noise
Please Download the audio scope for analyzing the sound wave patterns. http://www.zeitnitz.de/Christian/Scope/Scope_en.html.and also http://www.nch.com.au/wavepad/index.html for recording audio. There might be other sound wave analyzers out there, but I seem to like this one. I am a ham operator and I like Mathematics, Physics an also Electonics.
