Hi my name is Miguel Pea, Im from Venezuela and I going to teach in this assignment all about of

the reverb, I hope to help you understand a little more how the reverb differences can be useful in

own songs.

Lets talk about what the reverb is:

Reverb, short for reverberation, is an effect that is comprised of many different delayed signals

which creates a background effect that is similar to sound in a room, bouncing around. When you

are in a room and make a noise, the sound waves reflect off of various flat surface and this creates

an echoes type of noise called reverb. Because all of these reflections happen at different times

depending on how long it takes for the sound to reach the surface and back, reverb is basically an

incredibly large number of varying echoes. The direct sound hits the listeners ears before the

reflections. The difference between the two is referred to as pre-delay. All reverbs will have a

dry/wet mix control which will control output signals as a mix between the dry inputted signal and

the wet reverberated signal.

Theres two different types of reverb plugins: Algorithmic Reverb and Convolution Reverb.

Algorithmic Reverb:

Use algorithms to reproduce natural echoes and simulate the effect of reverberation. The

definition of an algorithm is a simple step-by-step procedure that is used in computer

programming to logically outline the steps the computer will take to solve something.

Algorithmic reverbs use multiple feedback delay circuits which creates a diminishing series of

sounds. The early reflections are controlled by variables such as room size, room shape and stereo

controls. The reverb time is generally less than 2ms. The computer produces a reverb sound based

on the settings on these controls which controls the variables in the algorithm.

The important features are the customization abilities with the room size and shape controls.

Another important feature is stereo capability which allows the reverb use up some space in the

width of the mix.

Convolution Reverb:

Is the digital simulation of reverb using a pre-recorded sample (called an impulse response)

of the modeled space. The computer generates output based on the convolution of the samples

of input audio and the samples of the reverb file.

Convolution is an advanced mathematical equation similar to cross-correlation that produces a

third modified version which leaves an overlap that can be utilized to create this reverb effect.

These can be real spaces, such as an auditorium or exotic places such as a famous concert hall.

An important feature of convolution reverb is its ability to mimic a variety of different room by

importing lossless audio files.

Sounds Different

Reverb algorithms from different manufacturers sound different for a number of reasons, most of

which can be traced back to the available processing power and the designer's approach to

algorithm design. Most reverb algorithms incorporate a complex network of delay-based

resonators to increase the complexity of the reverb tail, but unless these are set up very carefully,

different frequencies decay at radically different rates, giving rise to a metallic ringing effect. This

is fine if you're after the coloration of a plate reverb, but less welcome in a natural room

simulation. More processing power allows designers to use more building blocks, but the fine

tuning 'art' side of the process is still critically important.

The convolution reverb shines in all its glory, if your music requires large spaces such as orchestral

music. Here is unbeatable, thanks to the samples.

The good and the bad

Algorithmic reverb

Good:

Many adjustable and synchronized parameters.

You can create totally new sounds.

Lots of variety of algorithms and results.

Bad:

They are not necessarily natural.

The quality is very varied.

Convolution reverb

Good:

Faithfully reproduce the characteristics of the space that captures the moment.

There are many free libraries available including popular pulses units TC, Lexicon Bricasti,

etc.

Bad:

CPU consumption may be higher than a good algorithmic reverb.

The result may be less alive.

There are very few adjustable parameters.

The reverb quality depends directly on the quality of the library, and not all are equally

good.

Reflection

I hope I have been able to clear some doubts about the types of reverb there. The reverb is a great

tool for our musical productions, which has unlimited uses that can take advantage of huge way.

While taking into account the musical context.
