What do Common Electronic Waveforms Sound Like: sine, square, triangle, sawtooth

Details

Description

There are various common basic waveforms used in electronic circuits: sine wave, square wave, triangular wave, and the sawtooth or ramp waveform.

When these are listened to or hear these common waveforms sound very different, but al have their distinctive sounds.

The sine wave sounds very round and musically has little interest. This is because it does not have the richness of any harmonics - it consists simply of the fundamental as shown on the spectrum analyser screen output.

The square wave is rich in harmonics and it sounds quite harsh, but musically more interesting.

The triangular waveform sounds more rounded than the square wave, but has more interest musically than a sine wave.

Both versions of the sawtooth waveform sound very similar, and quite 'electronic' in their sound. They have a high content of harmonics because the sharp rise and fall of one of the edges means that this waveform is rich in harmonics.
