I've searched and not found much on them, can anyone give me a brief outline/point me in the direction of a brief outline? I have no clue what they do.

cheers

I'll try.
My lack of technical terminology might confuse you.

Let's say you have a volume envelop on your lead. What happens is, you can automate when the volume increases or decreases. So over the first say 16 bars, you've got the voulme down to -20 or whatever. By the end of the first 16 you've got it up to -10.

You can draw an envelope for "everything" really. Panning, FX sends, EQs, etc.

Extremely basic answer. One of these guys will be more detailed I assume.

Attack is the parameter that sets the speed at which an envelope or dynamics processor starts.

Decay is the time it takes for the enveloped setting to reach a sustained level after the Attack envelope.

Sustain - In a traditional envelope, the level at which an enveloped setting remains after the Attack and Decay stages until the key is released.

Release - With an envelope, Release sets the speed at which the envelope returns to its zero setting. In a dynamics processor, it sets the speed at which the processor stops working.

Just to be cheeky can I add a question to this? (Bandshell sorry to hijack your thread bro but its kinda along the same lines...)

Can someone also explain how to use envelopes to minimalize pops and cracks at the start/finish of audio samples?

Cheers

Use a fade in at the start, a fade out at the end.

Each spline of the envelope could be curved.
You can also have a fade control, although I have no idea what that does i've never used it.

Would that work with very small audio samples, like individual drum hits?

The fade in/out would have to be pretty steep wouldnt it?
