Description
Threshold is a paranormal investigation command center for capturing, monitoring, organizing, and reviewing field evidence in one place. Use Spirit Box Lab, record EVP audio, capture custom video, monitor magnetic fields, motion, vibration, and audio levels, take photos, and keep everything connected by Session and Area.
Create a Session for each investigation and preserve audio, video, photos, motion events, markers, notes, magnetic context, and Spirit Box Lab runs for later review.
SPIRIT BOX LAB
Spirit Box Lab uses calibrated live magnetic-field and device-motion activity to generate indexed word outputs from a curated 2,048-entry production vocabulary.
Outputs are driven by live sensor activity rather than released through a simple repeating word timer.
Choose a Session, Area, sensitivity, and spoken-output setting before beginning a run. Generated outputs, timing, contributing sensor activity, and Trigger Details are saved for later review and interpretation.
Free users receive 15 minutes of complimentary Spirit Box Lab monitoring time, with up to 5 minutes per run. Upgrade to Threshold Pro for unlimited Spirit Box Lab access.
CAPTURE INVESTIGATION EVIDENCE
• Record EVP audio • Capture video with Threshold’s custom camera interface • Use pinch zoom, precision zoom, and torch controls • Take rapid investigation photos • Monitor a fixed camera scene for motion-triggered events • Import supported audio, video, and photos • Save evidence directly to a Session and Area
MAGNETIC CONTEXT
On supported devices, Threshold can preserve magnetic activity alongside captured evidence.
• EVP audio and video can include synchronized magnetic timelines • Photos and Motion Camera images can include capture-time magnetic snapshots • Review readings, baselines, changes, activity levels, and timestamps • Add markers from a selected magnetic timeline moment
Rotating the device briefly recalibrates magnetic sensing. Threshold may display CALIBRATING before live readings resume.
If magnetic sensing is unavailable, capture and review continue normally without magnetic context.
LIVE INVESTIGATION TOOLS
Magnetic Field Monitor View live magnetic-field readings, baseline changes, peak activity, and individual axis values.
Motion Camera Monitor a fixed scene and capture images when visual movement is detected.
Vibration Beacon Monitor device movement and surface vibration with adjustable sensitivity.
Audio Level Meter Watch relative sound-level changes through a responsive live display.
REVIEW IMPORTANT MOMENTS
• Review audio with detailed waveform timelines • Review synchronized magnetic activity when available • Replay key moments • Add timestamped markers and notes • Review saved videos, photos, and motion events • Review magnetic snapshots saved with supported images • Review saved Spirit Box Lab runs and Trigger Details • Move evidence between Sessions and Areas
ORGANIZED BY SESSION AND AREA
Threshold keeps investigation evidence connected to its context.
Use Sessions for separate investigations and Areas for rooms, zones, or locations within each Session. Evidence can also remain Unassigned and be reorganized later.
SESSION EXPORT
Threshold Pro can export a structured Session package containing investigation details, evidence files, markers, Motion Camera metadata, Spirit Box run data, magnetic timelines, and magnetic snapshots.
Each subscription will automatically renew 3 days before the expiration date for
the same time period. Subscriptions can be cancelled at any time before the renewal.
