- Low Frequency Effects, a term used in surround sound mixing Low-frequency effects are mixed to a separate so-called LFE channel in modern movie sound production The LFE channel carries non-essential effects enhancement - such as the low-frequency component of an explosion - often at higher levels than the other channels The idea behind a separate LFE channel is to provide the extra low-frequency headroom needed to put low-frequency signal components on equal psychoacoustic footing with midrange signal components which require less energy for the same perceived loudness
- Low Frequency Effects channel This is a special channel of 5 to 120 Hz of information primarily intended for special effects such as explosions in movies The LFE has an additional 10dB of headroom in order to accommodate the required level
