Facts about reverb

Reverberation is present when any sound occurs in space. Reverb is created when a sound sends waves that flow in all directions. When these waves reflect on surfaces, the amplitude decays. Suddenly, the reflections die off. When there is no soundproofing, spaces will generate closely spaced reflections that will catch the listeners ear just before the sound dies. The human ear perceives these reflections as single continuous sounds. The music production industry is the perfect scenario for reverb since there is a wide variety of acoustical and mechanical techniques for creating reverb. Reverb can be found in almost every modern music production. 

Digital reverb can be classified as algorithmic and convolution. Algorithmic reverb mimics the effect through a series of calculations that imitate the sound of real spaces or create new sounds environments. Convolution reverb creates the effect by processing an impulse response which contains all frequencies. When using convolution reverb, sounds are perceived as more realistic. Digital reverbs are can be modified through several controls, including damping, pre-delay, diffusion, decay, and dry/wet balance. Reverb can be created through different techniques, such as room reverb, chamber reverb, hall reverb, spring reverb, and plate reverb.

The most popular types of reverb effects are the gated reverb and the reverse reverb. The gate reverb effect is non-linear and it produces a short explosive sound. The reverse reverb effect is reverb in reverse. This last effect produces a smooth transition into the dry sound as it introduces its sound before it is played. 

The reverb effect involves adding new signals to a mix. The new reverb signal should be equalized in order to attenuate low frequencies. It’s worth mentioning that when the reverb has too much energy in the low frequencies, the sounds can appear to have less clarity, whereas when the reverb has too much energy in the high frequencies, instruments and vocals will be unable cut through the mix.
