LFE Mixdown
“LFE” is short for “Low-Frequency Effects”. It is a
separate channel on a multi-channel disc, dedicated
for sound effects such as explosions in movies. In a
surround-sound system this channel is typically
directed to a dedicated sub-woofer.
When playing a multi-channel disc the two-channel
Analog Audio Outputs contains a downmix of all
channels except for the LFE channel. This is because
the LFE channel uses a different reference level and
cannot be readily mixed in with the other channels.
Normally this doesn’t pose a problem, as the only
thing missing is an occasional sound effect.
Unfortunately a handful of discs have been authored
incorrectly, and all low-frequency information from
all of the channels has been routed to the LFE
channel. Since the LFE channel is not part of the
downmix, the sound will be “thin” or “lean”.
