LFE, or Low Frequency Effects, refers to the deep, rumbling bass sounds that add depth and impact to audio recordings. These low frequencies are typically felt more than heard, creating a visceral experience for the listener. LFE is commonly used in music, movies, and video games to enhance the overall sound quality and immerse the audience in the audio. It is often produced by specialized subwoofers and can range from subtle vibrations to powerful, earth-shaking tones. LFE is an essential element in creating a truly immersive and dynamic audio experience.
