An Alesis Micro Gate noise gate. A noise gate or simply gate is an electronic device or software that is used to control the volume of an audio signal.Comparable to a limiter, which attenuates signals above a threshold, such as loud attacks from the start of musical notes, noise gates attenuate signals that register below the threshold.

The sound can be achieved in acoustically "live" or "dead" rooms, since all reverberation will be done inside the effects unit processor. The close mic sound is fed to the reverberation unit, then optionally to a compressor, and then to the noise gate's signal input. [16] The same sound from the close mic is fed to the noise gate's key input.
Ducking here works through the use of a "side chain" gate. In other words, one track is made quieter (the ducked track) whenever another (the ducking track) gets louder. This may be done with a gate with its ducking function engaged or by a dedicated ducker. A typical application is to achieve an impression similar to the "pumping" effect. The ...
This version adds Loudness, Noise Gate and Spectral Delete effects and adds Side-by-side view of waveforms and spectrograms. 2.3 September 29, 2018 This version adds Punch-and-Roll recording and upgrades to Macros, Play-at-Speed, Toolbars. From 2.3.2 on, a mod-script-pipe for driving Audacity from Python (can be enabled in Preferences). [27] 2.2
For example, in live sound reinforcement, a noise gate is often employed to mute or attenuate the microphone signal when the sound level falls below a certain threshold. This helps minimize the pickup of ambient noise and unwanted signals. 3. Radar systems: Signal gating plays a crucial role in radar systems, particularly in pulse-Doppler radar ...
Up to EAX 2.0, the technology was based around the effects engine aboard the E-mu 10K1 on Creative Technology's and the Maestro2 on ESS1968 chipset driven sound cards. The hardware accelerated effects engine is an E-mu FX8010 DSP integrated into the Creative Technology's audio chip and was historically used to enhance MIDI output by adding ...
Inserted devices can be connected in series to create a string of inserted devices. For instance, one could connect a gate, a compressor and an equalizer in series through the same channel's insert. Some digital mixers allow multiple internal effects to be inserted virtually, still others allow one or more third-party plugins to be inserted.
A noise squelch circuit is noise-operated and can be used in AM or FM receivers, and relies on the receiver quieting in the presence of an AM or FM carrier. To minimize the effects of voice audio on squelch operation, the audio from the receiver's detector is passed through a high-pass filter , typically passing 4,000 Hz (4kHz) and above ...
