Forensic Signal Demodulation Principles
In psychological horror and analog forensics (inspired by Silent Hill: Townfall), radio receivers act as transducers between physical fog and anomalous frequency spaces. Low-frequency ground waves (LF) and very-high-frequency (VHF) channels capture emergency calls that degrade across distance and interference.
- Carrier Offset Tuning: Rotate the Frequency Dial within 0.15 MHz of the beacon’s resonant frequency to recover speech formants.
- Bandpass Shaping: Center the audio bandpass between 800 Hz and 1.8 kHz to isolate human voice fundamental frequencies from marine static.
- Squelch / De-Hiss: Suppress atmospheric tape hiss and white noise without attenuating weak Morse code sidebands.
Interactive Controls & Shortcuts
Use direct on-screen dials or keyboard controls to fine-tune the receiver:
- Space or Enter on the primary button: Toggle receiver audio monitoring on and off.
- ← / → arrow keys on range sliders: Nudge frequency by 0.05 MHz increments.
- Auto-Tune: Snaps the dial directly to the nearest harmonic peak to observe ideal acoustic resonance.
- Report Export: Generates a verifiable JSON log containing signal-to-noise metrics, decoded transcript tokens, and frequency spectral characteristics.
