How does Ghost Radio work?
Learn the background and inner workings of the Ghost Radio app
Background
Ghost EVP Radio was a private project that actually never was intended to be released as a mobile app. Some years ago, a Swedish Paranormal investigation group created a suite of software tools to aid them during their investigations. These were specialized and rather complex Windows-based applications, which were pretty hard to use for someone outside the group. Some of them interacted with external equipment, like IR and sound sensors.
The mobile revolution meant that sensors and processing power suddenly were available in a portable and affordable format. Thus, the idea of creating an app, based on one of the Windows-based tools, was born. Exelerus, a small independent app/software publishing company also based in Sweden, became involved in the development of the mobile app version, which later was named Ghost EVP Radio.
How it works
The app relies on EVP formed by random selection. In the app the raw data is implemented as Brownian noise generation using one of the randomness techniques described below, which then feeds the analyzer process, “EVP formed by speech synthesis” to form EVPs.
Most of the other EVP apps (we have analyzed the ones that aren’t just for fun) rely more or less entirely on one of these two mechanisms to form EVPs. However, the approach that we have chosen seems to produce better results in most situations.
A word about Randomness
Almost all methods (digital and non-digital) for Paranormal communication rely on random events in one way or another, and Ghost Radio is not different in that aspect.
The current version of the app uses the following strategy to generate random events of good quality:
- If your device has a Magnetometer/Compass sensor, the Electromagnetic Field (EMF) measurements it provides are used as entropy for the random generation.
- If your device has an Accelerometer/Motion sensor, the motion measurements it provides are used as entropy for the random generation. If both sensors are available, both will be used.
- If neither an EMF nor Accelerometer sensor is available, the app will try to fall back and measure Wi-Fi/4G/3G/GPRS signal strength instead. The app does not need to send or receive any data to the Internet to do this; instead, it constantly measures the signal strength fluctuations and uses this for entropy.
- If none of the above are available, the app will use the most common way of generating random events on a digital device: Timestamp-based seed. This is kind of a last resort, since it is predictable: a specific seed will always generate the same sequence of random numbers. And to further increase randomness, in this case we use the Mersenne Twister algorithm paired with constant seed regeneration.
So if your device doesn’t have one of the required sensors (#1 or #2), keep your Wi-Fi or other network connection on (#3) to avoid using the standard random generation (#4).
Most competing apps that we have analyzed rely entirely on the standard way of random generation (#3), which is both predictable and isolated within the CPU and therefore isn’t a good source for Paranormal influence.
