5. Gated Reverb
-
Gated reverb or gated ambience in a studio processing technique that combines strong reverb and a noise gate. The effect is often associated with the sound of 1980s popular music. It was developed in 1979 by engineer Hugh Padgham and producer Steve Lillywhite while working with the artists TXC, Peter Gabriel and Phil Collins at Townhouse Studios in London.
The effect is typically applied to recordings of drums (or live sound reinforcement of drums in a PA System) to make hits sound powerful and ‘punchy’ while keeping the overall mix clean and transparent sounding. Unlike many reverberation or delay effects, the gated reverb effect does not try to emulate any kind of reverb that occurs in nature. In addition to drums, the effect has occasionally been applied to vocals.
1. Natural Reverb
2. Chamber Reverb
3. Spring Reverb
This initially introduced as a feature in Hammond Organs in the 1930s and 1940s. As these organs were sold mostly for home use, and as people were accustomed to the reverb of a church space when hearing organs, consumers wanted an effect to replicate this reverb.
Laurens Hammond, developer of the Hammond Organ, created this effect by repurposing a device designed at the pioneering Bell labs. This device used springs and wire to simulate the delay experienced during long distance calls. Hammond used this concept and similar materials to create a delay-based reverb effect called spring reverb.

An echo chamber is a hollow enclosure used to produce reverberation, usually for recording purposes.
A loudspeaker is placed in the room. The audio signal is sent from the mixer to loudspeaker, which plays audio into the room. This triggers the room acoustics to create specific reverb sound. A mic in the room then records the reverberant signal and sends it back to the mixer.
Now recording and mixing engineers had an isolated reverb signal to manipulate. The flexibility to separately process dry and wet signals and set dry/wet balance during the production process was a crucial development in audio production.
Reverb is created when a sound reflects off its surrounding surfaces, then these reflections again reflect off the surfaces, then the process continues creating a 'wash' of overlapping echoes. These echoes remain audible even after the initial sound source has been taken away.
In a natural reverb context, the dry/wet balance is determined by the distance between the mic and the sound sources. By playing close to the mic, dry signal is relatively louder than the room noise, leading to a dryer recording.
Playing further from the mic causes direct sound from the sound source to blend with the room noise. With the room playing a larger role in determining which sound waves reach the mic, a wetter sound is created.
