In the context of electronic music, an LFO (Low-Frequency Oscillator) and a VCO (Voltage-Controlled Oscillator) are both used for modulation but serve different purposes.
- LFO (Low-Frequency Oscillator): An LFO generates waveforms at very low frequencies, typically below the audible range. It is primarily used for modulation effects that alter the characteristics of sound over time. LFOs are commonly used for frequency modulation (FM)
