Basic Tremolo Operation
Tremolo, in its most basic form, is a periodic change in volume. A simple example is when the volume
of the output increases steadily for a fixed amount of time, then decreases steadily for a fixed
amount of time, and repeats that process over and over again. This is illustrated by the following
graph:
The blue line in the graph is known as the LFO. It changes the level of the output signal over time.
The frequency (a.k.a. “rate” or “speed”) of the LFO can be increased to get a more rapid change in
the output level, as shown in this graph:
