Applying too much reverb on a sound can make the overall mix muddy. Use of the right amount of reverb and the right decay time is important. Hence it allows the music producers to wait until mixdown before they commit to a particular reverb setting for every instrument. With artificial reverb, the amount of reverb being sent to each individual instrument or voice can be tweaked independently. Reverb can be generated artificially by using either digital technology or analogue reverb units. Since such productions rely heavily on overdubbing, reverb is very useful as it helps in blending different instruments and voices making it feel as if they were all recorded together in the same acoustic space.
In modern era multi-track recordings, musicians and sin gers often record their parts at different times and possibly in different studios around the world. Also, once you record wet, the reverb gets printed along with the main audio signal and it’s hard to get back the dry audio sig nal. It requires a great deal of time and experience to obtain good quality recordings using natural reverberation due to the fact that you need to be precise in selecting the right recording environment, microphones and optimum microphone placement techniques. This gives creative freedom to recreate all kinds of acoustic spaces. The reason that digital reverb is usually preferred over natural reverb is that it is much cheaper, it’s easier to tweak the reverb parameters and it offers more control with a lot of scope for creative freedom. It is used to recreate spaces which were not there during the recording process.
Reverb allows you to create a sense of space to an audio recording.
