Open Source Acoustic Drone Detection

VolAnti is an open-source acoustic drone detector built by Agam Rossen that uses a four-microphone array feeding a 2048-point FFT on an ESP32-S3 to identify the telltale sounds of spinning propellers, including quiet fiber-optic drones that don't emit RF. It runs multiple detection algorithms in parallel, including one without an adaptive noise floor so hovering, non-moving drones aren't filtered out as background noise. The project files are available on GitHub.
