I have the modded nvmixer but those features like Limiter, LFE settings, Acceleration settings.. What do they actually do?

I need help with:
* Limiter (Limits something but what?)
* LFE Setting (Dunno anything about this.. It's some Low-Frequency thing)
* Acceleration settings (Options are None, Safe and NVIDIA. What do they do?)
* Speaker Fill setting on Audio Firewall (Never heard..)

Google doesn't give straight answers so I decided to ask from here :P
