A door, valve, or other device, for stopping the passage of water through a dam, lock, pipe, etc.

A device which is used as an electronic "switch." Signals that are lower in level than a user-set point (threshold) do not pass the gate. It opens and passes the signal unaltered when the signal is sufficiently loud. A full function gate has adjustable attack (open) and release (close) times, and often a hold (duration) feature, as well.

A sound device that switches off the signal path when the signal falls below a certain predetermined level (threshold). Gates are typically used to ensure silence between pauses in the signal during vocal passages or to prevent ‘spill' between the close-proximity, multiple mics on a drum kit.

A gate frames its invitation by using precise components: an approach, twin pillars, crossbeam, door, latch, key, king and threshold. The twin pillars guard the opening to new awareness. The crossbeam spans the gulf between the pillars, uniting the space between them. The cross created by the meeting of beam and pillar is said to symbolize the passage into the transcendent, the mysterious boundary between inner and outer worlds. Hindering the passage through the gate are the door and latch, representing the veil and challenge posed by rigid patterns of thinking. The door blocks and opens, intimidates and welcomes. Its lock is the first barrier to overcome. The key symbolizes new insights and techniques for unlocking the mind's abilities. When the catalyst for transformation has done its work, the threshold of the gate is crossed, marking the transfer of a spiritual center of gravity from the known to the unknown. The threshold is perpendicular to the path that crosses it, creating a sort of compass that points to the four corners of the world. (adapted from The Temple in the House)

A transient processing device that turns a channel off or down whenever the program signal falls below a preset level.

a closely related process that essentially "cuts off" the incoming signal when the level drops below a predetermined level

a switch that turns off the audio when it goes below a defined threshold

a filter that turns audio off or down when it falls below a specified threshold.

A gate or noise gate is an audio switch used to mute signals below a set threshold level. It can be used to suppress background noise and hiss from valve (tube) amps, effects pedals, and microphones. See Dynamics Processor.

An electronic device that increases dynamic range by cutting off a signal when its level falls below a specific threshold. Used to control leakage of sound source into adjacent mics (ie drums).

A dynamic processing device that turns a channel off or down when the signal drops below a certain level.

a device that opens or closes a pathway by stopping signals that fall below a user-defined level. Audio gates often are used to salvage noisy tape tracks and silence "dirty" sound systems: The gate stays closed—blocking residual, low-level noise—until the audio signal's level exceeds a user-determined threshold. Then, the gate opens, allowing the sound to be heard. Gates can also be used to create effects such as gated reverb.
