Sawtooth Tone Generator

Introducing the Sawtooth Wave

As its name suggests, the shape of the sawtooth waveform resembles the teeth of a saw blade. It consists of a sine wave of the same frequency (e.g. 100Hz) and all the harmonics to infinity (300Hz, 500Hz, 700Hz, ...) at decreasing levels.

Since no real-world system has infinite bandwidth, it follows that perfect sawtooth waves are impossible to generate. In the time domain, this reverts to saying that switching from one level to other always requires some time, making the instantaneous transition found in the sawtooth wave impossible.

Generating a sawtooth waveform in the digital "sampled" world is not as easy as it seems. Even the most complex algorithm will has to tradeof the sharp edge in the time domain with spectral purity. Our algorithm has been designed to deliver the purest tone instead of the best looking waveform.

The sawtooth wave compared to...

Listen to how the sawtooth wave sounds in comparison to other classic waveforms such as the sine, square and triangle. Try to isolate the fundamental frequency by ear (it sounds equivalent to the sine tone) from its harmonics. Our default values are used here (1000Hz, 3s, -3dBFS).
