Sound Signal Spectrum

Demonstration of the time course of a sound signal recorded by a microphone and its corresponding frequency spectrum.

An online tool used can be found here: https://www.compadre.org/osp/pwa/soundanalyzer/.

On one screen, we simultaneously see the time domain (the course of the sound signal over time) and the frequency domain (the course of the frequency spectrum function generated by the Fourier transform).
