DeadWave is a paranormal app for iPhone that allows Instrumental Trans Communication (ITC) with spirits through electronic devices. The app is based on the theory of Electronic Voice Phenomena (EVP) that suggests communication with spirits or otherworldly entities on a recording device. The app uses Sound Manipulation (Transform EVP) to modulate sound waves in a manner that changes its characteristics on to a recording device. DeadWave provides four sound banks, an optional microphone input, adjustable audio effects including Echo, Reverb, Noise Gate, and Pitch, a four-band equalizer, and a visual ITC feature that uses the first-ever Virtual Video Feedback method.

This paranormal app works similar to a ghost box by providing "raw audio" that spirits can use to form speech. The app can be installed on your phone, making it easy to use at any time, especially when visiting a haunted location. However, there is no guarantee of communication with spirits or ghosts, and results may vary. Use at your own risk, and remember that building a connection with the other side can help improve communication.
