Scientific validity notes reflect methodology analysis. Tools marked as ITC or experiential have not been validated by mainstream science. Always establish environmental baselines.
iZotope, Inc.
Professional audio repair suite with AI-powered Spectral Repair and noise removal. Used by forensic audio analysts and film post-production. The most capable tool for isolating anomalous audio from contaminated field recordings.
Blackmagic Design
Industry-standard professional video editor used in Hollywood post-production. Free version provides comprehensive tools for frame-by-frame evidence review, noise reduction, colour analysis, image stabilisation, and video enhancement — essential for serious analysis of investigation video footage.
Audacity Team (open source)
The most widely used open-source audio editor in paranormal investigation. Standard tool for EVP review, spectrogram analysis, and noise reduction workflows.
Cornell Lab of Ornithology
Scientific bioacoustics analysis suite from Cornell Lab. The tool of choice for academic-level EVP and acoustic anomaly analysis. Provides publication-quality spectrographic analysis with measurement statistics, selection tables, and peer-review-ready output.
John Mulcahy
Professional room acoustic measurement suite. Used by paranormal investigators to establish acoustic baselines before investigations — characterising room resonances, standing waves, and noise floor so anomalies can be distinguished from environmental artifacts.
Teledyne FLIR
Professional thermal imaging analysis suite from FLIR. Opens raw RADIOMETRIC thermal image and video files from FLIR cameras, displaying true temperature data at every pixel. Essential for investigators using FLIR thermal cameras who want to analyse temperature anomalies beyond the camera's own display.
Queen Mary University of London
Advanced spectrographic analysis tool from Queen Mary University. Designed for music research but adopted by EVP investigators for its annotation layers, pitch tracking, and publication-quality spectrogram output.
Adobe Inc.
Professional DAW with spectrogram view, spectral frequency display, and batch noise reduction. Used by investigators who need to integrate EVP analysis with video evidence in a single Adobe workflow.
Airspy / SDR-radio community
The most widely used software-defined radio application for Windows. Combined with a low-cost RTL-SDR dongle, creates a sophisticated radio monitoring station for radio sweep investigation, RF anomaly monitoring, and frequency baseline documentation.
Onset Computer Corporation
Companion software for Onset HOBO environmental data loggers — the gold standard in scientific-grade unattended environmental monitoring. HOBOware reads logger data and produces multi-parameter time-series plots of temperature, humidity, light, and more — the baseline data backbone for serious overnight investigations.
Ocenaudio Team
Lightweight cross-platform audio editor with real-time effect preview. Popular with EVP investigators who find Audacity's workflow slow for rapid evidence review through long recordings.
Alexandru Csete OZ9AEC
Open-source software-defined radio receiver for Linux and macOS. The Mac and Linux equivalent of SDR# — provides spectrum display, recording, and radio monitoring with RTL-SDR hardware.
Joan Charmant
Free sports science motion analysis tool adopted by paranormal investigators for slow-motion review, motion tracking, and measurement of apparent physical movements in video footage. Provides frame-by-frame analysis with measurement tools.
Wolfgang Buescher (DL4YHF)
Highly configurable real-time spectrum analyser used in amateur radio, acoustic research, and paranormal audio investigation. Displays live audio as a scrolling spectrogram — used by researchers monitoring for infrasound and sub-audio anomalies.
Adobe Inc.
Free web-based AI audio enhancement from Adobe. Upload a recording and the AI removes background noise, room echo, and non-vocal content, leaving primarily vocal audio. Useful as a preprocessing step for isolating alleged voice anomalies from noisy field recordings.
GoldWave Inc.
Long-established Windows audio editor popular in the EVP community for its multi-file Document Window workflow, batch processing, and simple controls. Frequently cited in older EVP investigation guides and community forums.
GUIDE Infrared / InfiRay
Free companion analysis software for InfiRay (GUIDE) thermal cameras. InfiRay cameras are the most affordable genuine thermal cameras available (~£200-600), making this the thermal analysis entry point for investigators on a budget.
Stefan Bion
Pioneering ITC software that splits an audio source into random segments and reassembles them in random order. The theory: randomness prevents meaningful speech from forming unless an external intelligence imposes order. Used by serious ITC researchers worldwide since the 1990s.
SDR-radio community (plugin)
A plugin for SDR# that automates frequency scanning for ghost box-style ITC investigation using a software-defined radio receiver. Provides transparent, configurable sweep parameters unlike any hardware ghost box.
eXtremeSenses
Free ITC visual display software from eXtremeSenses using Perlin noise to present a shifting visual field for ITC image-based communication research. Similar in concept to thermal noise cameras used for ITC video work.
eXtremeSenses
Dedicated paranormal detection software from eXtremeSenses. Claims to detect electromagnetic and energy anomalies using PC hardware sensors. 100,000+ downloads. Includes ITC word generation and environmental displays. Methodology is disputed but widely used in the community.
Doug Haber (open source)
Open-source Python script that controls GQRX via its remote API to perform automated frequency sweeping for ghost box-style investigation on Mac and Linux. The transparent, scriptable SDR ghost box for non-Windows investigators.
