Low Frequency Oscillator. An lfo is an oscillator producing these waveforms at a very low frequency or pitch. In the context of lfos low frequency refers to not very many cycles per second.
This is typically 10hz. What are lfos low frequency oscillators. This pulse or sweep is used to modulate musical equipment such as synthesizers to create audio effects such as vibrato tremolo and phasing.
Frequency is expressed in hertz hz a.
Remember frequency refers to how frequently something happens. This time variant controller outputs frequencies in the subaudio range. This is typically 10hz. A low frequency oscillator often known as an lfo is another time variant controller that like the envelope generator can induce change in an oscillator filter or amplifier depending on which module is the destination of an lfo control signal.
