Hi, I'm Luth Oliveira from Salvador, Bahia, Brazil and this
presentation is for week 5 of "Introduction to Music Production"
at coursera. Today I will compare and contrast a algorithmic
and convolution reverb.

Reverb
Reverberation, in psychoacoustics and acoustics, is the persistence of sound after a
sound is produced. A reverberation, orreverb, is created when a sound or signal is
reflected causing a large number of reflections to build up and then decay as the
sound is absorbed by the surfaces of objects in the space – which could include
furniture and people, and air. (WIKIPEDIA.COM)
Importance
The reverb in a mix will give a sensation of space, pretending a real room, or
distance from the sound source. If you don't want to use the reverberation of the
room where the sound was recorded, it is important the usage of reverb plugins, wich
are divided in two categories: Algorithmic and Convolution.
Convolution Reverb
Convolution reverb uses an Impulse Response (IR) to create reverb. An impulse
response is a representation of how a signal changes when going through a system
(in this case the ‘system’ is an acoustic environment). An impulse response of both
real-life acoustic environments and electronic hardware reverb units can be created
and used. The advantage of convolution reverb is that it can accurately simulate
reverb and can sound very natural. The disadvantage of convolution reverb is that is
it computationally complex which can take up a lot of a computer’s processing.

Open Air, a example of Convolution Reverb
Algorithmic Reverb
Software reverb that does not use convolution creates echoes using mathematical
algorithms to simulate the delays that occur in reverb. The synthesis of echoes can
be performed much for efficiently on a computer using less processing. The trade-off
is that these algorithms rarely sound as natural as convolution reverb.

Room Reverb, a type of Algorithmic Reverb
Sound Comparison
I used a conga loop through different reverb types and configurations that you can
listen on soundcloud. The convolution reverb that I chose was the "Open Air" and the
algorithmic was the "Room Reverb", both Studio One plugins. The first audio file is
the loop with no plugins, the audio 2 and 3 where in the "Open Air" with, respectively
Impulse Responses: "Nice Drum Room" and "Parking Garage" . And the audios 4
and 5 were in the in the "Room Reverb", one with the "Drum Booth" preset and the
other with the

It's being a fantastic experience in learning and sharing knolegments with you. I hope
i was clear in the explanations. Have a nice course you all. Bye
