Natural Reverb Types

Room – A room is anything from a classroom to conference room. There is generally a short decay time of about 1 second: room.mp3

Hall – A hall is larger than a room, it could be from a small theatre with 1 second of decay up to a large concert hall with a decay time up to 2.5 seconds: hall.mp3

Church – The decay time of a church can vary between 1.5 seconds to 2.5 seconds: church.mp3

And Cathedral decay times can go above 3.5 seconds: cathedral.mp3

Remember, the sound of a room is not just the decay time. The materials it was built with make a huge impact on the character of the sound. Stone, wood, metal and tile all sound drastically different.

There are also a few other types of reverb that are not natural - these are Non Linear, Gated and Reversed.

Non-Linear has a decay that doesn’t obey the laws of physics: non-lin.mp4

Gated was a popular effect in the 1980s, but it’s sounding pretty cheesy these days: gated.mp3

Reversed sounds like this: reverse.mp3

Reverb Parameters

Reverb Type – What kind of reverb emulation it is. There are Halls, Rooms, Chambers, Plates, etc…

Size – What the physical size of the space is. This can range from small through large.

Diffusion – How far apart the reflections are from each other.

Pre-Delay – Sets a time delay between the direct signal and the start of the reverb

Decay Time – Also known as RT60, which is how long it takes for the signal to reduce in amplitude 60 decibels.

Mix (Wet/Dry) – Sets the balance between the dry signal and the effect signal. When you have the reverb effect on an insert you need to adjust the wet and dry ratio, when you are sharing the reverb in a send and return configuration you want the mix to be 100 percent wet.

Early Reflection Level – Controls the level of the first reflection you hear. Early reflections help determine the dimensions of the room.

High Frequency Roll Off – Helps control the decay of high frequencies (as it is found in natural reverb).

Tips For Using Reverb

—Using pre delay can help keep your vocals up front, while still giving them space.

—Try to keep decay times short for faster tempo music.

—Filter out low frequencies before the reverb to keep it from sounding muddy

—Try de-essing the reverb to reduce harsh sibilance.
