Spectra: Ghost Detector & EMF

Something may be in the room with you. Spectra turns your phone into a professional paranormal investigation instrument that never fakes a reading.



Unlike typical gimmick ghost hunting apps, every number on screen comes directly from real hardware inside your smartphone—the magnetometer, microphone, barometer, gyroscope, and accelerometer—processed live on-device with zero script or artificial triggers. No fake spikes, no random sound clips, no theatrics. Just raw, unexplained physical data explained in plain language.



REAL PARANORMAL TOOLS & SENSOR SUITE:



🧲 REAL EMF METER & DETECTOR

Your device's magnetic compass sensor reads local electromagnetic fields in real time. Spectra spends a few seconds learning the room's ambient baseline, then flags exact spikes climbing above it—the classic first sign of anomalous activity. Track RAW, BASE, and Delta (Δ) values in microtesla (μT), follow the directional vector toward the disturbance, and read the trace to easily separate house wiring or appliances from moving anomalies.



📻 ITC SPIRIT BOX & LIVE TRANSCRIBER

Instrumental transcontact directly through the device. Advanced on-device speech processing transcribes vocal frequencies during your session. In a quiet, still room, ask your questions and monitor real-time speech responses detected underneath ambient room sound.



🎙️ ADVANCED EVP RECORDER & SPECTRUM ANALYZER

Capture Electronic Voice Phenomena with a real-time audio spectrum analyzer mapping deep rumble to past human hearing range. When sustained signals appear outside normal voice bands (below 85 Hz or above 4000 Hz), Spectra automatically saves a audio clip tagged with its peak frequency. Detection pauses while you speak so captures are never your own voice. Export raw, uncompressed WAV files or use built-in pitch-shifting to bring infrasonic and ultrasonic signals into audible hearing range.



🌡️ BAROMETRIC PRESSURE & COLD SPOT TRACKER

The built-in barometer tracks ambient air pressure changes instantly. While weather drifts slowly, paranormal cold spots, drafts, and sudden room shifts cause sharp barometric jumps. Monitor live pressure drops to validate environmental changes alongside EMF spikes.



📊 MULTI-CHANNEL PRESENCE & RESONANCE

A composite intelligence algorithm weighs every sensor channel honestly. Voice replies carry the highest weight, EMF fields are verified, and multi-sensor correlations trigger higher presence levels faster. Integrated motion-rejection algorithms automatically discount EMF and pressure fluctuations while you walk, preventing false positives caused by your own movement.



📖 SKEPTIC'S FIELD MANUAL

Tap into an integrated, plain-English field guide for every sensor. Learn what each reading measures, how to interpret frequency spikes, and which natural, boring explanations to rule out first so you can investigate like a true skeptic.



Note: Sensor measurements, frequency analysis, and audio captures reflect real physical hardware measurements. Interpretations of anomalous environmental changes remain up to you.



Grab your phone. Kill the lights. Start your investigation.
