per second (or 440 Hz), you will hear an A note, independently of the
shape of the electric signal (the waveform ).
There were di erent kinds of waveforms an oscillator could produce,
and all had di erent mbres, which could be used to approximate dif-
ferent instruments, or to create various kinds of sounds.
sine wave triangle wave
sawtooth wave square wave
For instance, a sine wave oscillator produces a pure but dull tone, while
a square wave sounds much harsher and has a very rich harmonic con-
tent.
Nowadays, oscillators can be much more sophis cated, and in addi on
to the tradi onal single-waveform oscillators, you will encounter many
other ones that all sound di erent and are based on di erent synthesis
techniques. Here are a few examples:
− Virtual analog techniques strive to reproduce the warm and imper-
fect sound of the oscillators in analog synthesizers.
− FM (frequency modula on) is the use of a simpler oscillator to
modulate the frequency of another oscillator, resul ng in a widely
di erent mbre from the original.
− Physical modelling techniques aim at simula ng the physical struc-
tures of acous c instruments (winds, strings, etc.) so that the re-
sul ng sounds behave like the instruments they’re modelled a er.
