===Multi-latch gating===<!--[[Multi-latch gating]] redirects directly here-->
The invention of a technique, called '''multi-latch gating''' by Jay Hodgson, common in classical music recordings for years, is often credited to producer [[Tony Visconti]], whose use on David Bowie's "[["Heroes" (David Bowie song)|Heroes]]" may have been the first in rock.<ref name="Hodgson">Hodgson, Jay (2010). ''Understanding Records'', p.&nbsp;89. {{ISBN|978-1-4411-5607-5}}.</ref> Visconti recorded Bowie's vocals in a large space using three microphones placed 9 inches (23&nbsp;cm), 20 feet (6.1&nbsp;m), and 50 feet (15.2&nbsp;m) away, respectively. A different gate was applied to each microphone so that the farther microphone was triggered only when Bowie reached the appropriate volume, and each microphone was muted as the next one was triggered.

"Bowie's performance thus grows in intensity precisely as ever more ambience infuses his delivery until, by the final verse, he has to shout just to be heard....The more Bowie shouts to be heard, in fact, the further back in the mix Visconti's multi-latch system pushes his vocal tracks [dry audio being perceived as front and ambience pushing audio back in the mix], creating a stark metaphor for the situation of Bowie's doomed lovers shouting their love for one another over the Berlin wall."<ref name="Hodgson"/>
