Instrumental Trans Communication (ITC) is the communication with spirits through electronic devices. EVP theory suggests that we can communicate with spirits or otherworldly entities on a recording device. The method that these spirits seem to be using is known as Sound Manipulation (Transform EVP). Though we are not exactly sure how this process is done we know that it involves the modulation of sound waves in a manner that will change it’s characteristics on to a recording device.They may also communicate in real time (Opportunistic EVP). Simply put, spirits can change sounds in order to form speech and therefor have the ability to communicate. Features: 4 sound Banks Optional Microphone input Audio effects that are fully adjustable including Echo, Reverb, Noise Gate, and Pitch. 4 Band Equalizer Visual ITC feature that uses the first ever Virtual Video Feedback method. This paranormal app is made to work similar to that of a ghost box by providing "raw audio" that spirits can use to form speech. This device can be put on your phone so you can have it with you, you never know when you might end up at a haunted location. You have to work on building a connection with the other side. This will help improve your communication. Disclaimer: There is no guarantee you will be able to communicate with spirits or ghosts. Results may vary. Use at your own risk.
