LFO
An LFO is a low-frequency oscillator used to modulate another sound parameter.
Also called: Low-frequency oscillator
Level relevance: introduced at Nat 5; tagged for every later level where the same concept remains useful.
Explanation
An LFO can create repeated movement such as vibrato, tremolo, filter sweeps, or pulsing effects. It usually controls another setting rather than being heard directly as a pitched sound.
