DSP descriptions?

Is there a repository for explanations of the various DSP effects available? I've used kX drivers for some time now and have a decent grasp of the basics, and the flow and layout of the DSP, but some of the more advanced functions escape me.

ProFX seems easy enough to understand, as is the majority of the Basic items. This leaves a considerable amount of effects as a mystery to me, with effects such as the Dynamics Processor and all of APS just to name a few.

A push in the right direction would be much appreciated!

Maddogg6 will become famous soon enough

Most of the 'effects' are common - use google (Dynamics processor for instance - is a type of 'Compressor/Limiter' - and can boost low volumes, while suppressing peak levels in an audio stream, among other functions, like 'Ducking' - where a second audio stream, upon its presence, will automatically lower the volume of the first audio stream - commonly used in TV/Radio, where background music is a little lower when a speaker/host/talker speaks.)
But - it can be adjusted to do other things as well - The D.P. plugin alone is almost like a screwdriver... 'What can I make with a screwdriver?' - the answers are almost unlimited.
edit: if you think about the word 'dynamics' and apply that idea to audio - you would see that 'compressing' dynaimcs does just that - boost low volumes, while lowering or even just limiting the higher volume /edit.

Thus, IMHO, 'The guide' would be too big for a single person, or even a small group to manage - as well as, for instance, some effects (like some from from Max. M.'s UFX) are more unique - and playing with/ listening while adjusting are just simpler to get an idea of what they do...

Not to mention - 'what does a bird sound like?' - some things, words just can't describe as easy as just hearing it.

So, if google turns up nothing (example google 'audio effect dynamics processor') and the plugins 'presets' as labeled, doesn't clue you in, then
1) look at the plugin source (right click on it in DSP - choose 'Edit' or 'Edit Source' - and *maybe* some comments could indicate what the plugin does)
2) same as 1 but, learn what the DSP code does and learn to understand what is happening (sorta like reverse engineering, only not in reverse )
3) If you dont hear the effect of a plugin - ask here about that specific plugin here. Someone will describe what it does or how to use it properly, but you will likely need to have some basic understanding of audio to understand the replies.

hope thats helpful...

As Maddogg6 indicated, even though you may not consider these plugins as basic, they are fairly standard plugins, and should work in a similar manner to any standard web descriptions that you find for the type of effect.

BTW: Some plugins need to be used in conjunction with x4/div4 plugins to work correctly (x4 -> plugin -> div4).

i.e.
APS Compressor/Expander plugins
Noise Gate 2T plugins (IIRC).

In addition to what Maddogg6 said, you should search the forum for more info on how a plugin should be used (there is often such info in the thread where the plugin was initially released, etc.). Note that you may have to read the entire thread for a full description of the plugin (i.e. changes that may have been made since it was first released, etc.). In most cases the first post of the thread will be updated with any new info (but not always), but it still does not hurt to read the full thread, as it may contain more details, and it may have the answers to any question(s) you might have about the plugin (i.e. someone else may have already asked the same question(s) that you have).
