Effect: Presence

Description of effect: 
Tries to mimic the behavior of the "presence" function in different kinds of amplifiers. The effect can be applied to all kinds of sounds though the result may vary.

Main benefit:
This will add a sense of "overdriven" amplification to your sound. Guitars and bassguitars will like this in particular as it in many cases will give a certain "power" or "distorted" look to the result. Note that this effect is not a filter, even though the bass and treble will be greatly enhanced.


Description of parameters: 
Valve vs. Sold state This will switch the behavior of the effect. The general quality of a "valve" amplifier and a "solid state" amplifier has little to do with the relative quality of this effect. The two different settings can be very useful in different situations. You will just have to try...

Strength Slider will adjust the actual quantity of the effect. Not that some sounds will be affected relatively little by this effect, and that is why the slider is very powerful, not to be set too high in most cases.

Preview: Press the 'Preview' button to test the effect to see if it is tuned properly. It is quicker than applying the effect and making an undo...


What could go wrong 
Actually, it very easy to "over-do" the effect. Some sounds are affected very little, and others extremely much. That depends on the actual frequencies of the sound. Most probably, it is very hard to exactly know what the result will be. 

For you that want to know more... 
By saying that this effect "mimics an overworked amplifier" means that the waveform is restricted "not to move too quick". This is called slew rate, and in this effect it is implemented as restricting the "derivative" of the signal. First the deviate is taken and thresholded, and then integrated back (tech-stuff...?).
