- geopsy: a graphical user interface for visualization of waveforms, basic signal processing and advanced signal processing. The later are implemented within plug-ins that can be included or not:
- H/V spectral ratio and spectra
- Ambient vibration arrays
- Multi-channel Analysis of Surface Waves (MASW)
- Signal stacking for noise reduction
- Damping estimation from random decrement
- Plus-minus refraction (not yet available)
- Time-frequency analysis
- Particle motion
Array response
- warangps: monitoring of real-time positions for WARAN, computation of theoretical array responses.
- gpfksimulator: educational tool for simulating the array response of plane wave(s) with arbitrary direction and speed.
Array post-processing
- max2curve: tool for estimating the average and the uncertainties of various processes: FK, HRFK, SPAC, HVTFA or simply curves.
- spac2disp: tool for estimating the reliability of experimental auto-correlation curves.
Utilities
- gpsignal: computes synthetic signals
