Hearing a Sine Wave Oscillator

Let's hear what a sine wave sounds like. In this web page, we are using a plugin called JSyn which allows Java Applets to create sound on a web page. The Applet does not start the sine wave immediately. It only starts it when you check the check box.
To Do:

Turn down the volume on your speakers.
Click on the check box below.
Turn up the volume. You should hear a smooth tone coming from you speakers.
If you do not hear any sound, please visit the trouble shooting page.
Click on the box again to turn the sound off. You will hear a small pop sound when it is started and stopped because we are doing it so abruptly. Later we will learn how to start and stop a sound gradually using envelopes.
