Sawtooth Tone Generator

Introducing the Sawtooth Wave

As its name suggests, the shape of the sawtooth waveform resembles the teeth of a saw blade. Perfect sawtooth waves can only be imagined, since no real-world system has the infinite bandwidth required to produce instantaneous transitions. Frequency-wise, the sawtooth wave consists of a sine wave of the same frequency (e.g. 100Hz) and all the harmonics to infinity (300Hz, 500Hz, 700Hz, ...) at decreasing levels.

Generating a sawtooth waveform in the digital "sampled" world is not as easy as it seems. Complex algorithms are needed to trade off sharp edges 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).
