    Low Frequency Oscillator. An oscillator that is designed primarily to operate below the threshold of human hearing (though not exclusively) and to provide modulation function. Often found in synthesizers and effect devices. For instance, vibrato, a cyclic variation of pitch is generated by modulating the audible portion of the signal with an LFO which, depending on its pitch of the LFO, will create a slower or faster vibrato.
