In professional audio and telecommunications, '''attack time''' is the time between the instant that a signal at the input of a device or circuit exceeds the activation threshold of the device or circuit and the instant that the device or circuit reacts in a specified manner, or to a specified degree, to the input.<ref>{{cite book|last=Corey|first=Jason|title=Audio production and critical listening : technical ear training|year=2010|publisher=Focal|location=Oxford|isbn=978-0-240-81295-3|pages=99}}</ref> Attack time occurs in devices such as clippers, peak limiters, compressors, and voxes.
