After 7 years in the shadows, The dedicated IP Radio Hybrid Spirit Box has been resurrected. Originally established in 2015, the AD-II Spirit Box is back for 2026 completely rebuilt into a modern, high-fidelity framework while faithfully retaining the classic aesthetics that researchers originally loved.
The AD-II is a true Hybrid Spirit Box, giving paranormal investigators the ultimate flexibility in the field. Seamlessly switch between randomized internet radio sweeps and built-in offline audio banks on the fly, all controlled by an intuitive interface.
Whether you are a seasoned ITC researcher or an amateur investigator, the AD-II provides a professional suite of tools to push your sessions further.
🎛️ TRUE HYBRID ENGINE
Use the physical-style toggles to switch your audio source instantly:
IP Radio Mode: Connects to a massive, randomized pool of live internet radio stations with regional radio settings to pick from Mixed or localised regions.
Internal Bank Mode: Switch offline and utilize the 10 built-in, custom-engineered audio banks for localized sessions without needing WiFi or Cellular data.
LIN / RAN Sweeping: Choose between traditional Linear (sequential) scanning or Non-Linear Random scanning to fire the 10 active audio slots in an unpredictable sequence.
🎚️ STUDIO-GRADE FX PROCESSOR
Shape your ITC audio in real-time. Accessed via the settings panel, the AD-II now includes a professional suite of audio effects to clean, manipulate, and enhance your session:
Noise Gate: Eliminate background hiss and only allow strong signals through.
Pitch Control: Shift the audio pitch up or down in real-time.
Reverb & Echo: Add spatial depth to potential EVP responses with adjustable mix and feedback.
EQ & Drive: Adjust Bass, Treble, Low-Pass Filters (LPF), and overdrive distortion.
Synthetic Static: Blend in a custom synthetic static floor to aid in white-noise coupling.
🌍 GLOBAL ITC CAPABILITIES
The AD-II is built for investigators worldwide:
Multi-Region IP Banks: Filter the live IP radio station pools by language (English, Spanish, French, German, Italian, Japanese, and more) for precise phonetic targeting based on your location.
Instant UI Translation: Type in your preferred language in the settings, and the app's entire interface will instantly translate to accommodate you.
📻 THE OBSERVATION LENS
The classic AD-II speaker grille returns. Watch your audio pulses visually resonate from behind the hardware slatted mesh with the built-in, real-time waveform visualizer, providing instant visual feedback when a signal breaks through.
