EVP or no EVP that is the question

Based on one of the threads in this section there are pro and anti evp people (tryed to find a term that wouldnt offend people)
Lets discuss this here, the good the bad and the ugly... for me evp is something that we dont hear when its being recorded, doesnt mean we dont hear it... we must filter out certain noises naturally unless needed, so quite noises we might hear the end of it. Look at taps, how many times have they gone whats that and on the recording theres a voice or noise that didnt come through the tv cameras...
Ghosts are energy so why not make sound which is energy...
