Proximity Effect

This curve is meant to mimic the physics phenomenon that the

 

 

 

closer your ear (or a microphone) gets to a sound source, the

 

 

 

more the bass is emphasized.

Presence

This curve gives the signal a little more life when you want to get

 

 

 

the listener's attention.

Distance

Sometimes you want the signal to not be so much of an attention

 

 

 

grabber.

Combfilter Combo

This is just whacky. This is what happens when you send a stereo

 

 

 

signal through two different comb filter curves--Channel A using

 

 

 

a resonant base of 125Hz while Channel B uses a resonant base

 

 

 

of 50Hz.
