A low-pass filter that you can apply to a FlexBus or Main that’s in a surround sound format, to feed low- frequency sound to an LFE channel as part of a surround sound mix. The filter will exclude any sounds above your chosen frequency setting to the audio that is sent to a sub-woofer in the LFE channel. It helps keep unwanted and unnecessary audio from being sent to the sub-woofer and increases playback clarity.
A Frequency control lets you choose which low frequency range you want to include, and a Trim control lets you set the level of the resulting LFE channel. If it is multi-channel but has no LFE channel available, such as a 5.0 format, then this plugin does nothing.

Limiter
A true peak limiter that is capable of looking 64 samples ahead of the input, in order to limit the audio in a very smooth fashion. An Input control lets you adjust the level of the incoming signal, while Threshold and Release controls let you adjust the limiting that’s being done. A graph shows you an analysis of the audio as it’s processed, with a visual indication of what parts of the signal are being affected by this plugin.

It is used to detect and reduce the peaks of an audio signal so that the overall level can then be boosted without clipping, thus reducing the dynamic range of a given signal, similar to compression.
