Description
The app calculates the variations of the frequency of a sound around frequency defined by the user with very high precision. The error in the frequency is less than 0.04%
The app plots the fundamental frequency versus time.
The app records the values of the frequency as a function of time in a text file that can be emailed.
The app can measure sound Doppler Effect: J.A Gmez-Tejedor, J.C Castro-Palacio y J. A. Monsoriu.
