EVP's can be recorded anywhere and at anytime. The voices do not always sound human. Many times they are just faint whispers or one word or maybe a sound such as knocking. We use a standard cassette recorder, always with a new tape. We also use several digital recorders. We usually start off by asking questions such as "Is there anyone here with us" and giving ample time for the ghosts to respond before asking our next question. We feel it is best to have one person ask the questions. And it is much easier to spot them on playback if you were as quiet as possible when your questions are being asked, but we have picked up strange voices and sounds among our chatter or while setting up equipment. If you must talk while recording evps always speak in a normal voice, never whisper.
