EVP Recorder - Spotted: Ghosts

EVP Recorder, developed by independent software builder Spotted Ghosts, is an Android application engineered specifically for field researchers, ghost hunters, and audio enthusiasts investigating Electronic Voice Phenomena (EVP). Unlike novel entertainment software that plays pre-recorded audio files or synthetic sound triggers, this application functions as an unadulterated digital audio recorder and real-time sensor logging platform.

Architecturally, the application pairs clean digital audio capture with mobile hardware telemetry. It reads raw data directly from onboard smartphone sensors, surfacing a real-time telemetry display that includes an Electromagnetic Field (EMF) meter (using the device’s magnetometer), proximity readings, ambient light intensity, atmospheric barometric pressure, temperature, and humidity. On the recording front, the app features a "Sound Detection" mode (VOX) that automatically triggers recording when ambient audio exceeds a user-defined threshold, as well as the ability to maintain background audio capture while the device screen is powered off—a vital function during extended night investigations. Furthermore, a built-in "EVP Analyzer" studio allows researchers to trim audio segments, adjust playback speed, and shift pitch frequencies in real time to isolate faint acoustic anomalies.

Comparing Spotted Ghosts EVP Recorder with standard mobile voice memos highlights its specialized field utilities. Standard voice recorders employ aggressive noise cancellation algorithms designed to strip out faint background whispers or ambient static—the exact high-frequency frequencies ITC researchers aim to record. Spotted Ghosts avoids artificial noise gating, capturing raw uncompressed acoustic input. Additionally, the inclusion of integrated screen video recording allows researchers to document live sensor gauge spikes alongside synchronized audio waveforms.

Technical evaluations indicate that the app writes captured sessions directly to a structured directory on the device’s storage using the legacy .3gp audio container format. Monetization operates on a freemium model: while core features are ad-supported, a paid monthly or annual subscription tier removes advertisements, unlocks VOX sound detection, enables screen-off background recording, and grants access to custom UI theme downloads.
