Low Frequency Oscillator; LFO
Technical term used in electronics and computing for a circuit that generates low-frequency signals, often below 20 Hz, used in synthesizers, modems, and control systems.
This synthesizer has a built-in Low Frequency Oscillator.
低周波発振器の周波数を調整してビブラート効果を得る。
Adjust the LFO frequency to get a vibrato effect.
発振器 is a general oscillator, while 低周波発振器 specifically generates low-frequency signals.
高周波発振器 is a high-frequency oscillator, contrasting with the low-frequency range of 低周波発振器.
Compound of 低周波 (low frequency) + 発振器 (oscillator). A straightforward technical term with no historical irregularities.
