Vibrometer

Vibrometer is a precision vibration measurement, spectral frequency analysis, and background seismic monitoring utility for Android. Utilizing your device's built-in tri-axis accelerometer, gyroscope, and sensor fusion algorithms, Vibrometer turns your smartphone into a portable seismometer, vibration analyzer, and seismic activity detector.

Whether measuring mechanical motor vibrations, evaluating structural stability, diagnosing appliance noise, or experimenting with seismic waveform detection, Vibrometer provides responsive real-time visualization and precision data export.

KEY FEATURES

• Live Tri-Axis & Combined Waveforms: Track instantaneous acceleration along the X, Y, and Z axes alongside vector magnitude and intensity in real time.
• Real-Time Seismograph Charting: Smooth, high-refresh line graphs with peak amplitude indicator, elapsed time tracking, and customizable visible points.
• Flexible Sensor Modes: Capture data via Accelerometer, Gyroscope, or balanced Sensor Fusion with adjustable sensor weights.
• Advanced Signal Processing Methods:
- RAW: Unprocessed real-time sensor motion signals.
- STABILIZED: Baseline drift and gravity-compensated stabilization.
- RMS (Root Mean Square): Effective vibration energy and intensity over time.
- FFT (Fast Fourier Transform): Frequency domain spectral decomposition (RAW FFT, RMS FFT, STABILIZED FFT).
• Background Earthquake Monitoring: Intelligent background seismic detection with tailored sensitivity profiles (Stationary, Portable, Vehicle, Sensitive), smart scheduling, and instant alert notifications.
• Local File Export: Save and export full vibration sessions to CSV / Text format in your chosen device directory for scientific plotting and analysis.
• Granular Measurement Controls: Fine-tune sampling intervals (from 1 ms up to 5,000 ms), rolling window size, sensitivity thresholds, axis legends, and peak metrics.
• 100% Privacy-First: All calculations, sensor processing, and recordings happen completely on your device. No sensor data is ever uploaded or transmitted externally.

PRACTICAL USE CASES

• Industrial & Home Appliances: Diagnose unbalanced fans, motors, washing machines, and 3D printer vibrations.
• Structural & Acoustic Monitoring: Detect structural tremors, resonance, and ambient floor vibrations.
• Seismic Research & Education: Hands-on exploration of seismic waves, P/S wave concepts, and earthquake vibration physics.
• Automotive & Transit Diagnostics: Track vehicle suspension smoothness and cabin vibrations.

IMPORTANT NOTICE

Vibrometer is designed for general informational, educational, and hobbyist analysis using consumer mobile sensors. Smartphone hardware sensors are not certified industrial or seismological monitoring instruments and must not be used as critical emergency alarms or life-safety warning systems.
