Equipment Log 📻

Overview

This page documents the equipment used in Dead Air Project sessions.

The purpose of this log is transparency and repeatability.
Equipment is listed as used — not as endorsement or proof.

Recording devices

ITC Research P-SB7 Spirit Box (Rev. 7)

• Function: radio sweep / ITC
• Usage: selective sessions
• Sweep Rates: 50ms, 100ms, 150ms, 200ms, 250ms, 300ms, 350ms
• Notes:
  • Sweep rate unchanged during sessions
  • Audio captured externally when possible

Røde VideoMic Me-L

• Function: external microphone for mobile recording
• Used with: iPhone
• Purpose:
  • improved signal clarity
  • reduced handling noise

iPhone (Voice Memos)

• Function: raw session recording
• Format: uncompressed / default app settings
• Role: primary capture device in some sessions

iPhone (Just Press Record)

• Fuction: raw session recording
• Format: default settings
• Role: Primary Capture device

Olympus VN-8000PC

• Function: digital voice recorder
• Usage: EVP-focused recordings
• Notes:
  • internal microphone
  • minimal onboard processing

Tascam DR-05

• Function: digital voice recorder
• Usage: EVP-focused recordings
• Notes:
  • Omni-directional condenser microphones
  • sensitivity up to 125dB SPL

External Speakers

JBL Micro Wireless

• Old-fashioned, flat and narrow sound profile
• Limited frequency response (no deep bass, no sparkle)
• Bad for music playback
• Excellent for Ghost Box / Spirit Box use
• Speech and noise artifacts come through clearly
• Small, simple, no sound “enhancement” or processing
• Does not mask EVP-type anomalies
• Powered speaker – practical for field use

Procaster OZC-01

• Flat, uncolored and slightly muffled sound
• Very limited frequency response
• Not too much audio processing, quite heavy bass
• Well-suited for Ghost Box / Spirit Box output
• Speech fragments and noise artifacts stand out clearly
• Minimal sound processing or enhancement
• Does not smooth or mask potential EVP content
• Simple, utilitarian speaker behavior benefits analysis

JBL Go (1st. Generation)

• Boxy, sharp-edged and mid-focused sound profile
• Narrow bandwidth with almost no low-end
• Highly effective for Ghost Box / Spirit Box use
• Digital noise, syllables and transient sounds are clearly exposed
• Early-generation design with minimal DSP influence
• Does not beautify or compress audio artifacts
• Compact and practical external speaker for field work

Measurement equipment

ST1393 EMF Smart Sensor Meter

• Function: electromagnetic field measurement
• Usage:
  • environmental reference
  • anomaly correlation
• Notes:
  • readings logged but not interpreted as causal
• Dual Testing Functions (detect and measure the electric field radiation and magnetic field emission)
• Range: 20Hz-300Hz magnetic field and 20Hz-3500MHz electric field
• Temperature Measurement
• Audible and Visual Dual Alarm

MelMeter 8704-r

• State of art EMF sensor
• Usage:
  • enviromental reference
  • anomaly correlcation
• Measures EMF, & ambient Temperature
• EMF “Burst” (100msec) mode feature for rapid EMF fluctuation
• EMF Min/Max capture
• Rapid response ambient temperature measurement
• Temperature min/max capture
• Red night view Backlight Display with On/Off Button
• High intensity Red Flashlight

Audio processing tools

All processing is performed after recording, never live.

iPad-based tools

• WavePad
• Ferrite
• TwistedWave
• Wavebox Audio Editor
• Brusfri

Processing may include:

• gain adjustment
• EQ
• noise reduction (reference only)

Raw audio is always preserved and prioritized.

iPhone-based tools

• Psoft Audio Player

Windows-based tools

• SonicVisualiser Mainly for large EVP-session analyzation
• Audacity

Session references

Individual session pages may reference this log using:

• specific devices
• recording chains
• processing steps

This allows each session to be reviewed in context.
