Description
The app calculates the fundamental frequency of a sound with very high precision. The error in the frequency is less than 0.04%
The app plots the fundamental frequency versus time.
The application can be used to tune musicals instruments.
The app can be used to measure sound Doppler Effect: J.A Gómez-Tejedor, J.C Castro-Palacio y J. A. Monsoriu. "The acoustic Doppler effect applied to the study of linear motions", European Journal of Physics, 35 (2), 025006 (9pp), 2014. doi: 10.1088/0143-0807/35/2/025006
