Types of reverb
I know this subject its all over the internet but if by some chance you don't know this already it's very important that you do, so let's get start it.
First, you need to know there are 5 types of reverbs and they depend on the size and shape of the room that the sound echoes in, these reverbs are: Room, Hall, Plate, Spring, and Chamber.
This 5 types of reverbs are divided by 2 kinds, the early reflections which are the sounds that arrive at the listener after being reflected maybe once or twice from parts of listening space, such as walls, ceilings and floor and the late reflections which are essentially every other sound we hear after the primary reflection.
The most basic type of reverb is the room, both the room reverb and the hall reverb are designed to simulate the natural sound of acoustic spaces, but the difference between them is the decay time, typically the room reverb is around .2 to 1 second.
Similar to the room reverb because both simulate the natural sound of acoustic spaces, but as I mentioned before their decay time its whats sets them apart, the decay time of the hall reverb is from 1 to 5 seconds, which give your sound a huge feel.
Plate reverbs were one of the first types of artificial reverbs used in recording, the plate reverb is the broadband resonance generated by vibrating a large metal sheet, the vibrations generated through this process are what creates the reverb.
Just as the Plate reverb this one is also man-made, the spring reverb is the broadband resonance generated by vibrating one or more metal coils held under tension, what this means basically is that it has a bouncy quality to it, due to the timing between echoes.
This reverb uses a loudspeaker that plays the sound in a room with a very reflective surface and then a microphone would pick it up again, including the effects of reverb.
