Step-by-step procedures: what you need, when to do them, and what can go wrong.

A procedure

Record an EVP session

A fixed-duration listening session with a source, a log and a close.

What it is

To make a recorded listening practice repeatable and honest about what it is.

At a glance

When
A fixed time of day for a series; otherwise any quiet period.

How to do it

  1. Set the room, the recorder and the source.
  2. Ask one question and state the duration.
  3. Record for the fixed duration.
  4. Replay once at normal speed and once slower.
  5. Log fragments without interpreting them yet.
  6. Write a reading and mark the fragments rejected as noise.
  7. Close the session and decide whether to keep or delete the audio.

What you need

  • A recorder
  • A noise source
  • A timer
  • A log
  • Headphones

A worked example

A ten-minute white-noise session with the question 'what am I not hearing?' Four fragments are logged; two are rejected as room noise.

What can go wrong

  • Every fragment is treated as a voice.
  • The session is used to make health or money decisions.
  • The audio is kept without a record of what was rejected.

Background

Keeping a record

The audio file, the log and the reading.
