This Spirit Box has two main modes.
Mode 7 engine scan each 100ms noise and human tones of less than 100 ms, working as a classic spirit box (with mode7 running you can activate new NR7 for less static noise).
Mode White noise scans up to six audio banks of noise (no human tones) to give spirits a bed of noise for capturing EVPs that must be reviewed from the recorded session.
The Rec button starts your device camera to record video and audio of your session, for review possible evidences of intelligent communication (You can light the Torch if your device have flash built in, activate it just after pushing Rec in the app and before start recording video in camera menu, touch the flash symbol, very useful in dark places)
