Editing Sound reinforcement system (section)

====Effects====
[[Reverberation]] and [[Delay (audio effect)|delay]] effects are widely used in sound reinforcement systems to enhance the sound of the mix and create a desired artistic effect. Reverb and delay add a sense of spaciousness to the sound. Reverb can give the effect of singing voice or instrument being present in anything from a small room to a massive hall, or even in a space that does not exist in the physical world. The use of reverb often goes unnoticed by the audience, as it often sounds more natural than if the signal was left "dry" (without effects).<ref>[http://www.harmony-central.com/Effects/Articles/Reverb/ Reverberation]. Harmony-Central. Retrieved on January 23, 2009.</ref>  Many modern mixing boards designed for live sound include on-board reverb effects.

Other effects include modulation effects such as [[Flanger]], [[Phaser (effect)|phaser]], and [[chorus effect|chorus]] and spectral manipulation or harmonic effects such as the [[Exciter (effect)|exciter]] and [[harmonizer]]. The use of effects in the reproduction of 2010-era pop music is often in an attempt to mimic the sound of the studio version of the artist's music in a live concert setting. For example, an audio engineer may use an [[Auto Tune]] effect to produce unusual vocal sound effects that a singer used on their recordings.

The appropriate type, variation, and level of effects is quite subjective and is often collectively determined by a production's audio engineer, artists, [[bandleader]], [[music producer]], or musical director.
