WithStrings Software

Software for Android Devices And Sundry
(free apps with no ads, nothing sneaky)

Audio Analyzer. Simple app will read audio input from your device much like an oscilloscope: the sensitivity and time window can be adjusted (shown on the upper graph). The data captured provides an input to an FFT function that generates a frequency spectrum display in the lower graph. The spectrum is displayed with variable vertical sensitivity and log or linear scales. Cursors can find the datum or peak for both the time and frequency displays. Time and frequency data can be written to a spreadsheet compatible file.

The leftward screen shot shows a 440Hz tuning fork captured in a 0.05 second time window. The rightward screen shot shows the same 440Hz tuning fork captured over an one second interval.
