The RECOVIB.Feel is connected to an Android device via a USB connection. The supplied android application allows for streaming real-time vibration data on a chart in the time domain and in the frequency domain (FFT-based computations). RMS values are displayed as well. In the velocity and displacement mode, several filters are applied to derive the velocity and displacement curves. The data are then displayed on a chart in the time domain and in the frequency domain with five possible FFT-bas
