SpectraTrace

SpectraTrace turns your device’s real sensors into a set of investigation instruments — and tells you exactly what each one measures. INSTRUMENTS • M1 — a magnetic field meter built on the device’s three-axis magnetometer. Level scale, live strip chart, learned baseline and event detection, with data export for every sample. • REM — sensor-triggered word prompts. A magnetic, thermal, acoustic or touch event picks a random word from the list, shows it and speaks it. Every session is saved with time, source and magnitude. • Spectrum — the magnetic field as sound: a continuous noise bed that brightens and swells as the field changes, so you can hear it without looking. Tap the octave bands of its analyser to cut them from the noise and clean the sound. • Frequencies — a live 20 Hz–20 kHz spectrum of what the microphone hears, with the voice band marked, an adjustable event threshold and…
