WebFree, Simple and Easy to Use. Simply enter your desired frequency and press play. You will hear a pure tone sine wave sampled at a rate of 44.1kHz. The tone will continue until the stop button is pushed. The tone generator can play four different waveforms: Sine, Square, Sawtooth and Triangle. WebI pulled out one of my math-books and figured out how to write the sine-function: Since sin (x) has a period of 2*pi, sin (2*pi*x) has a period of 1/Frequency of 1Hz. Thus, sin (440*2*pi*x) has a Frequency of 440Hz. The last thing that was unclear to me was how to get the array-length and element-count right!
