I am starting to use reverb more now and have been trying to do a little reading on it. I want someone to confirm some of my understanding and also answer a simple question.

I think that pre delay is the time period before the reverb that is audible to humans starts, before this is some diffuse small reverberations that cannot be heard.

I am assuming this is related to the size of the room and damping etc, the reverb time, is the time the reverb is audible? If so what is the decay? I thought this was the time it took to die away.

Also one final question, on the basic 'cubase reverb b' it has a room size setting and a damping and pre delay and reverb time setting.

I dont understand why the room size setting is there, as I thought this would be perceived as combination of pre delay, damping and reverb time?

Thanks to anyone that can help.
