Sonic Analysis of the Redlands UFO Tape Recording

Abstract

The February 4, 1968 UFO sighting at Redlands, CA was accompanied by an intense, distinctive sound that was recorded as a background sound on a magnetic tape recording being made by Reverend Julian Vigh at the Bethel Christian Church. A rescue Emergency Vehicle (EV), with its siren operating, happened to be deployed in Redlands at the time of the UFO sightings.  An informal inquiry by several Redlands University professors attributed the background sound on the Vigh recording to the EV siren. Subsequently, I performed independent comprehensive detailed sonic analyses of the tape background sound and the EV siren, and documented these analyses in a 1969 report intended for inclusion as an independent technical appendix in a book on the Redlands UFO sightings then in preparation by authors David Branch and Robert Klinn. This book was never completed and published. The independent technical appendix is released and published here for the first time. Detailed tape analyses revealed and quantified a number of sonic anomalies. Present day concluding comments are offered that place these anomalies in the context of other investigative reports of the Redlands UFO sightings that appeared in the press subsequent to the writing of the appendix in 1969.
