Raymond Cass - EVP PioneerBy Bobby Garcia
Electronic Voice Phenomena (EVP) has been an essential part of paranormal study for over a half century. Raymond Cass was an influential researcher into this phenomena and few investigators are aware of his seminal contributions.

As an avid practitioner in acoustics, he quickly became a prominent figure in EVP research and began working with some of the better known researchers in the United Kingdom.
One aspect of his auditory work stood out from many others at the time: he was not only able to record more efficiently and clearly than others, the voices he heard came in what is called a polyglot form. This means that his recordings were speaking in several different languages all at the same time, or even bouncing from language to language with each word spoken. He came under fire from critics because most of his recordings were at the 127 Mhz frequency and were suspected to have been anything from bleed-through from airplanes to land based sources was such as ham radio operators, radio stations, or other public broadcasts. He also used a radio receiver to record while in his office.
All these reasons could be viable criticisms except for one thing: the voices spoke in foreign languages and mentioned his name. Some of his recordings went from German to French to English and then back to German at any given point. Some even mentioned Raudive after he had passed away as if conveying messages from Raudive himself!
The voices would also answer questions in polyglot form -- questions that Cass had asked beforehand. It was thought that his psychic connection and mediumship abilities were a conduit for the voices coming through. That aspect of his research made him stand apart from Jurgenson and Raudive, who were new to the paranormal field when they made their discoveries.
One popular opinion today is the belief that a good bulk of EVP can be obtained within the infrasound spectrum (19 Hz and lower). This is lower than what the human ear is normally thought to be able to hear audibly. Cass was using the 127 Mhz frequency, which is considerably higher. Jurgenson had set his radio frequency at 1445-1500 KHz, now called the Jurgenson Frequency. With all these varying frequencies within the audio spectrum, it only goes to show that EVP research has advanced as far as one would think considering many in the paranormal field are still researching for a more widely used frequency to emerge as the "door to the other side."
Today, some of his work can be found on different websites including one dedicated to Cass by the Raymond Cass Foundation. The Parapsychic Acoustic Research Cooperative, or PARC, released a compilation of Cass's work called The Ghost Orchid for everyone to analyze and come to his or her own conclusions. It includes his polyglot recordings throughout his career and has some of Raudive's work, as well. Although information about Cass isn't as abundant as Jurgenson and Raudive, his contribution to the early years of EVP research was just as important.
He opened the casual observer's eyes and spent a great deal of his time working to prove the validity of his recordings to his critics. You can take the first step of experiencing his work for yourself by going to the dedicated Cass website with his audio clips, or you can download The Ghost Orchid at the PARC website. Whatever conclusion you come to of his research, you will surely develop an appreciation for the many hours of Cass's dedicated work.
