In a scientific publishing house in Paris in 1853, a French bookseller, printer, and inventor by the name of Edward Leon Scott B. Martinville came up with what he called the imprudent idea of photographing the word.

His idea was to make a machine that would replicate the human ear in order to capture spoken words.

Scott called this process phonotography, the self-writing of sound.

On March 25, 1857, Scott received the patent for the phonograph,

and three years later, on April 9, 1860, Scott recorded an unsettling rendition of A. Clair de la Loon,

and it wasn't until almost 20 years later that Thomas Edison invented the phonograph,

which allowed Scott's song to be played for the very first time.

This audio is believed to be the very first sound recording in history.

Although it's a little difficult to listen to, Scott's recording is a stark reminder of just how far

we've come over the last 160 years. Never before has it been so easy for us to capture and share

audio at a moment's notice. From complex recording booths to simple handheld audio devices,

it seems as though we are never far from a microphone.

This technology has given paranormal investigators the ability to finally document their

experiences in a more meaningful and scientific manner.

In fact, it is believed that the very first electronic voice phenomena, or EVP, was recorded

in 1938, using Thomas Edison's phonograph, just seven years after

Thomas Edison had died. Now just over 80 years later, hundreds of thousands of researchers,

as well as unknowing bystanders alike, have recorded what many believe to be undeniable

evidence of something real, but unexplainable. From spirit voices to

disembodied footsteps, the quality and quantity of the phenomena being recorded is quite

literally out of this world. Tonight, however, we're going to focus on some of the audio recordings

that seem to point to a more physical yet unknown source. From our local state parks and
