Frequency analyser: A new Android application for high precision frequency measurement
We present Frequency Analyser, an AndroidTM application for measuring the fundamental frequency of a sound wave with very high precision in a frequency range between 100?Hz and 11?kHz. The application allows exporting the data of frequency as a function of time to an ASCII file. Several examples of application to Physics and Engineering teaching experiments are presented.  2015 Wiley Periodicals, Inc.
