Infrasound Recorder for Android

Infrasound Recorder is an educational app designed for Android devices, enabling users to capture and analyze low-frequency sounds generated by natural and man-made events. This application targets a range of phenomena including volcanic eruptions, sonic booms, and earthquakes, providing a unique tool for researchers and enthusiasts alike. It operates on Android OS 7 Nougat and above, ensuring compatibility with modern devices.

The app functions by recording audio through the device's microphone, filtering out frequencies above 80 Hz to focus on infrasound. The processed data is then sent to a secure server where it is analyzed, and a sound pressure plot is generated. Users can run the app in the background, allowing for multitasking while recordings are made. Data is stored locally on the device, with privacy measures in place to ensure anonymity during transmission.
