Waves LFE360 Manual Do Utilizador

 

 

 

 
The LFE 360° is a very steep Low Pass Filter designed to filter the audio in your 
LFE channel similarly to what the usual encoders will do to it. The Filter has 
about 60dB per octave roll off from the Frequency set.  
 
The LFE360° has a mono component and a 5.1 multichannel component which 
will affect only the .1 channel and pass the others on without any processing.  
 
The Frequency commonly used is 120Hz as suggested by one of the leading 
encoding providers. Sometimes 80Hz can be used. Because the filter is very 
strong it may create some peak growth and clipping if the input is quite hot. 
Sometimes there may be a pop when engaging the filter. If further clipping is 
apparent after the filter is engaged, you have a Gain control and you can use a 
Trim control to reduce the Gain by the overshoot amount or adjust the gain 
manually. It will control only the Gain of the LFE channel even in the Multichannel 
component.  
 
You can use the LFE filter to preview how the encoder’s LFE filter will affect your 
audio, or apply it on to the master. 
 
It is recommended to insert the 5.1 channel component just before the M360 
Manager. This way it will filter the LFE and the Sub signal will only be affected by 
the sub Low Pass filter and not the LFE filter.  
 

 
The LFE is the channel known as .1 (point one). The channel’s name allegedly 
stands for Low Frequency Effects and some say Low Frequency Enhancement.  
In the Film soundtrack industry it was used for sound effects such as dinosaur 
footfalls, explosions, earthquakes and other lovely effects that are supposed to 
make you feel as if the earth really is shaking under your seat and add spice to 
the on-screen drama.  
 
Nowadays the LFE channel is still used the same way in Film soundtracks, but in 
music production it is sometimes mistaken to be the channel that is played back 
by the Subwoofer. While it is usually played back by the Subwoofer, using it to 
provide a Split reproduction for the Low frequency material in the other channels 
is usually something that is done in real time during playback by the playback 
system. Playback systems vary in quality and specs so it is wise to leave the 
Bass Management job to happen in playback.
