I will be teaching about “Compare and contrast an algorithmic and convolution reverb. Demonstrate the difference and the important features in both types of reverb.”
Reverberation, what is it?
Reverberation is the persistence of sound in a particular space after the original sound is produced.
Reverberation, what is it?
Reverberation is the persistence of sound in a particular space after the original sound is produced.
A reverberation is created when a sound is produced in an enclosed space causing a large number of echoes to build up and then slowly decay as the sound is absorbed by the walls and air.
Why do we need it?
Reverb is an important effect because it brings a space-feeling to our mix.
Depending on the kind of feeling/impression we’re looking, we’ll choose a specific type of reverb.
Types of reverb
If you don’t want to record your song in a natural reverberated place, you will need to choose in your DAW what kind of reverb is better for your work

You will have the choice between two main types : algorithmic and convolution reverb.
Algorithmic vs Convolution reverb
There is one mathematical algorithm for each reverb: room, hall, etc…

This reverb is recreating a reverb effect of a non-existent place

Convolution reverb is going to recreate the reverb of a real existing place, for example, Royal Albert Hall in London

This reverb is recreating a reverb effect of a non-existent place
To create this mathematical calculation, first of all, sound engineers have to study the reverb behavior of the place

Convolution reverbs use real sound samples, recorded from real rooms (or modified but based on real recordings in some cases) known as “Impulse Responses”
How to choose?
Algorithmic: You adjust a lot of
parameters Needs much less
CPU power
Convolution reverb:

Algorithmic: You adjust a lot of
parameters Needs much less
CPU power But if its misused
the result will be disappointing

Convolution reverb: Recreates the
reverb of a real place

Convolution reverb: Recreates the
reverb of a real place
Sounds more natural

Sounds more natural
But needs a lot of CPU power & you onli can choose from a limited number of pre-studied places

I think both concepts are very complicated. I tried to explain them in a very basic and simple way

A choose to do a short lesson because I want the reader to remember the main principles when the lesson is over
