The Sound Analyzer JavaScript model records the sound from the computer's microphone and displays its frequency spectrum.  It is designed for classroom demonstration and student experimentation.   For example, measure sound from pipes with different boundary conditions and estimated the length of the pipe.

The Sound Analyzer JS Model was developed using the Easy JavaScript Simulations (EjS) version 6.  It is distributed as a ready-to-run html page and requires only a browser with JavaScript support.  This model runs on all platforms, including mobile devices.
