EVP is short for ' electronic voice phenomonon' evps are captured on recording devices such as digital recorders , also devices such as a ghost box or spirit box can transmit evps in real time. these responses to our questions are considered to be evps and are voices of the dead.
EVPS can be classified into two groups , class A evps and class B evps, our organization only considers class A evps as evidence of the paranormal. Class A evps are direct responses to our questions and are clear enough to determine what the response is. There are evps of residual sounds that we also count if we can not find a natural source for these sounds.
