How ianmaddocks/paramoter-audio-flight-computer works

ParaVario is embedded flight-computer firmware for paramotor pilots. Its main loop samples sensors and handles controls, then updates flight state and guidance; audio, Bluetooth, and the Wi-Fi page expose the resulting cues and information. GPS-dependent features are enabled at runtime, while the microphone supports noise-responsive volume, RPM, and spectrum. The README documents several capabilities whose implementation details were not sampled; those links use README evidence rather than implying source inspection.
