Theory of Operation (Only for nerds) ...
It has been reported that paranormal activity is evidenced by sounds inaudible, or barely audible, to the human ear. Animals, whose hearing is more acute at higher frequencies than ours, are able to detect supersonic sounds, generally above 12-15 kiloHertz or so. For example, dogs are reported to behave oddly during supernatural events. Sounds of very low frequency, less than a hundred Hertz or so, are normally felt rather than heard by humans. The built-in microphone circuitry in most handheld devices is designed to detect frequencies in the audio range, but there is some residual response from the circuitry at the very low (subsonic) and very high (supersonic) frequencies.
Ghostroid uses fast software-based Infinite Impulse Response (IIR) filters to measure the level of sub- and super-sonic sound pressure waves arriving at the microphone. It also measures the audible sound level. The three ranges are shown on the Ghostroid display via three meters, which move dynamically and are updated several times a second. The Para Normal Quotient (PNQ) is calculated from a formula that sums the sound levels in the sub- and super- sonic ranges, and subtracts the audible range value. This yields a number which increases as the sub- and super- frequencies (which are difficult or impossible for us to hear) increase, as compared to the audible frequencies.
The PNQ value is shown by a set of concentric bands at the centre of the display. High PNQ values may be caused by a variety of events: Low frequency rumbling (e.g. from heavy trucks or machinery), High frequency noises (e.g. dog whistles, or keys jangling) as well as Supernatural phenomena (please don't drop your Android when you run away in fright!)
Ghostroid is a port to Android of the well-established "Pocket Ghost" application for Windows Mobile. Although I personally remain sceptical about the existence of paranormal activity, and the effectiveness of this application to detect it, I have received several reports over the years of Pocket Ghost being successfully used by paranormal investigators. Here are a couple of quotes:
1) "I have used the pocket ghost program on my I-mate Jasjam and in all cases the Sub-sonic and Super-sonic reading peaked at 85 to 90 and did not drop down until the visions (or what ever they were) had gone."
2) "I have seen your program successfully used by a professional parapsychologist during an investigation in London."
3) "I am a member of several paranormal groups and investigate the most paranormally active sites within the U.K. On one such investigation a parapsychologist was using your 'Pocket Ghost' to great effect."
By using the magnetic compass found in your phone as an electromagnetic field (EMF) detector, Paranormal Recorder is able to turn on an audio recording only when there are abnormal EMF levels.
The recordings created by Paranormal Recorder often contain unexplainable noises and voices. Researchers have given these types of recordings a name, electronic voice phenomenon, or EVP.
Cited by many as a breakthrough in paranormal research, Paranormal Recorder has seen almost 1500 examples of EVP with associated abnormal EMF levels shared with the world.
Creating a paranormal recording is simple.
1. Press the 'Start EVP Detection' button and leave your phone plugged in and near an area of suspected paranormal activity for an hour or two.
2. Press the 'Stop EVP Detection' button and select the 'Analyze' tab. If there was any paranormal activity selected your recording will be listed.
3. Although you left Paranormal Recorder running for hours, there should only be a couple minutes of paranormal activity (if any) detected. Listen through the disruptions, classify them, and share the results to SoundCloud for other paranormal investigators to assist analyzing.
If you are not getting results, try another location and make sure your EMF thresholds are set correctly. The default settings should work best, but some areas may have different background EMF levels and need adjustment.
Join the hunt for paranormal activity today with Paranormal Recorder.
From seasoned Paranormal Investigators to Paranormal enthusiasts, this application is the application to have to document all the tedious information and evidence gathered in an investigation, in another words NO MORE WRITING REPORTS. This application will allow the investigator to free up the need for paper and pen, watches, and end of the investigation report summary. All the basic logging is done by the push of a button when activity occurs. You can also use other ghost hunting apps on your phone while this is still running in the background. Works very well with our Ghost Catcher Camera app...
Time Stamping: This is EXTREMELY important to validate your evidence against video and evp’s and other investigators findings.
GPS Locating: This will mark your exact location of the investigation
Note Additions: The ability to add notes to each and any occurrence that may take place.
Automatic Report Formatting: The final report is structured on the way the investigation is conducted.
Email and File Saving: You have the ability to email your final report for print out or manual changes you would like to make. It also saves the final report in your files in your phone for additional access.
At the start of your investigation you just add your name, case name, and case number. Next you will be taken to a screen where you have Investigation options you can choose from such as: During Setup,Initial Sweep, Room Investigation (Each time this is pressed a new room is added to the report with the option to name the rooms, they are listed numerically), Outside Investigation, Live DVR Viewing, & During Breakdown.
After hitting that button you will be taken to the choices screen. In which you can choose from Voices Heard, Sounds Heard, Shadow Figure, Full Body Apparition, Mists, Cold Spot, Q & A Meter, Q & A Light (these last two allow you to enter each question and document the response by a button press), EMF Fluctuation, Temp. Fluctuation, Personal Feelings, Personal Experiences, Light & Orbs, Energy Drain, & a spot for other activities not listed, as well. When you are done with one part of the investigation just hit home and it will take you back to the Investigation options screen. You then press the button to start the next part of your investigation. If a button is pushed accidently, just go back to the previous screen. When the investigation is complete just press End and you will be given the option to save and email the report.
That’s it. The full investigation is fully documented. The time stamp takes it right down to the second so no mistakes are made as to when activity occurred. This will make your clients feel better as well as giving you more credibility to your report.
