Tuned to 98.0 MHz. Signal strength 0 percent.
Ghost Box layers session logging over the spirit box engine. It analyses the live signal for amplitude, spectral flux, centroid and voice-like structure, and writes timestamped entries you can review or export, including markers you drop yourself while listening.
Optional microphone input is analysed on the device and never routed to the speakers or uploaded. Every event label describes an audio observation - a spike, a spectral change, voice-like activity - rather than asserting a cause.
Logging and analysis. The sweep engine is shared, but Ghost Box measures the live signal — amplitude, spectral flux, spectral centroid and voice-like structure — and keeps a timestamped record of events and your own markers that you can export.
A measurable change in the audio: a level spike, a sudden change in the spectrum, or a stretch that looks voice-like. Each entry is labelled with what was measured rather than with a cause.
No. Microphone input is analysed on the device. It is not routed to your speakers, which would cause feedback, and it is never uploaded.
A JSON file with the session’s start and end times, each detected event with its timestamp and measurements, and your markers with their notes. It opens in any text editor.
AM, FM and shortwave-style bands, plus a random option. They change the frequency range shown and the character of the simulated receiver; no real radio is tuned.
This is an instrument and a sound tool, provided for entertainment and experiment. It describes what it measures and does not identify the cause of anything it shows.
