First, select your tone or tune and the frequency plot parameters. Then, click Start Animation.
Next, click on one or both of the green buttons to plot either a time or a frequency domain.
Now start the MP3 music player

You can stop the plots at any time (red button) in order to freeze them for better viewing. To start a new plot change the tone and/or parameters and click Start Animation again.

Note the difference between white noise and brown noise: white noise has a flat frequency spectrum whereas brown noise decreases in power by 12dB/octave.
