Modulation Effects
Modulation effects are things that swoosh, pulse and warble—from phase shifters to flangers
to choruses. Why are they called modulation effects? Well, if we consult a dictionary, we
discover that ‘modulate’ in the electronic world means to “alter the amplitude or frequency
of (a wave) by (using) a wave of a lower frequency to carry a signal” (definition courtesy of
The Oxford Encyclopedic English Dictionary, Third Edition, thank you very much). That
modulating wave is what causes all that swooshing, pulsing, and warbling.
