The Portal is an experimental ITC (Instrumental Transcommunication) tool developed by Paranormal Shadows UK. It is designed to optimize the use of the Portal/Wonder Box or similar devices, but it can also be used alone. The app was created by Steve Huff of Huff Paranormal, who was looking to experiment with vocal banks from various age and gender people.

The Portal sweeps randomly between 7 short single file reversed human speech vocal banks, including young male and female, middle-aged male and female, elderly male and female, and 1 whisper bank. During your sessions, you can ask questions and look for intelligent replies, and it is recommended to keep the audio reversed for better validation of audio manipulation. The app also features a new randomized sweep rate.

Overall, The Portal is a unique and specialized tool for those interested in paranormal investigations and experimental ITC. Keep in mind that it is an experimental tool, so results may vary. The app is available for free on the Android platform and is compatible with Android 9.0.
