This mathlet generates tones from two sine waves. The frequencies of each sine wave can be set. If the frequencies are close together the combined sound exhibits the feature of "beats". The waveforms can also be displayed to show the corresponding visual feature of beats.
The mathlet can display either or both sine waves and the mixed waveform which is the average of the two.
