Sine Tone Generator

Introducing the Sine Wave (Pure Tone)

Sine Waveform
The most fundamental sound is the sine wave, characterized by a single frequency without any harmonics. Sine waves can be easily recognized by ear, as they sound clear and pure.

In 1822, French mathematician Joseph Fourier discovered that any waveform could be broken up as a combination of sine waves with different amplitude and frequencies. The discipline of reducing a complex waveform to a combination of sine waves is called Fourier analysis, and is fundamental to sound processing.

As sine waves are made up by a single frequency, they are best suited to test audio systems at a particular frequency.

Sine Square Sawtooth Triangle
Listen to how the sine wave sounds in comparison to other classic waveforms such as the square, sawtooth and triangle. Try to isolate the sine tone in the other waveforms, by tuning your ear to the fundamental frequency. Our default values are used here (1000 Hz, 3 s, -3 dBFS).
