Digital Voice Recorder

Tape recorder with an external microphone and high grade tapes or digital voice recorders are with out a doubt one of the most important pieces of equipment that you should have in you investigators toolbox.  audio recorders are used for many different purposes throughout an investigation.  Recorders are used for interviews, spontaneous thoughts,  your notes and electronic voice phenomena (EVP).


You have to use a external microphone when recording EVPs (ghosts voices).  If you rely on the internal microphone you will also be recording the internal gears and motors and this will make your tape worthless.  Any sound you hear on the tape could not be used as evidence because of this, so use the external mic, they are pretty inexpensive.  The type of tape that is most often recommended is high bias tapes or metal tapes.
Digital audio recorders - This recorder is small and easy to carry.  You can also use the voice activation feature so there is less audio to review.    I use this for my notes as well.  Most units record the time of the recording as well which is very useful.  When using audio recorders be sure to state the location, time of investigation, and investigators names.


When recording investigators names it would be wise to have each individual present state their own names, which will make it easier for distinction amongst voices heard on the tape during review.  Voice activation mode should be deactivated on tape recorders during use when electronic voice phenomena is trying to be achieved due to the fact that it usually cuts off beginnings of words, sentences, and phrases.   This is not necessary with digital recorders and they actual seem to work better in voice activation mode.
