Spektrocom is a free Windows application that generates continuously shifting visual noise patterns — using Perlin noise algorithms and colour cycling — and presents them as a display field for ITC image research. The concept is analogous to EVP Maker for audio: the noise field provides a constantly changing visual substrate, and ITC researchers attempt to observe and document patterns that appear to form meaningful images.
ITC image research has a long history predating software tools — early ITC image work used TV static and water surface reflections. Spektrocom provides a controlled, reproducible digital equivalent. Session recordings can be made by screen capture software, and apparent images can be timestamped and extracted as evidence. The software is used alongside audio ITC tools in combined multi-modal sessions.
Dokumenting sessions and having multiple blind reviewers assess images without priming is essential if results are to be taken seriously. Despite the methodological challenges, Spektrocom has a committed user base who report compelling and apparently corroborated ITC imagery. eXtremeSenses also produces Angelus ITC Video (paid) for more advanced video-based ITC sessions.
