GateVerb

GateVerb Gated Reverb Plugin (AUv3)
GateVerb is an audio effect plugin that can run standalone, or in any AU compatible host application such as Logic Pro or GarageBand.
Overview
GateVerb is a super-simple and CPU-friendly stereo reverb with a retro vibe. Pre and post-effect filters provide additional tone-shaping, and the switchable gate processing stage allows the recreation of the gated reverb sound made famous on many an 80's hit, as well as an emulation of a "reverse reverb" effect in realtime. And of course, you can simply switch off the gate, for those times when you just need a straightforward no-frills reverb.
Controls
Active - Toggles the effect On or Off. You can use this control to A/B your settings with the original signal and this will fade gradually between the two with no distracting pops or clicks!
Reverb Controls
Size - Varies the size of the emulated reverb from a small room to very large hall.
Damping - Varies the amount of high frequency damping applied to the reverb tail. As damping is increased, the reverb effect becomes "softer".
Width - Sets the stereo spread of the generated reverb from mono, to wide stereo.
Wet - Sets the level of the generated reverb, including the filter processing.
Dry - Sets the level of the dry / incoming audio signal.
Filter Controls
HPF - Sets the cutoff frequency of a high-pass filter, which is applied to the signal sent into the reverb processing.
LPF - Sets the cutoff frequency of a low-pass filter, which is applied to the output of the reverb processing.
Gate Controls
Gate - Turns the gate processing stage On or Off. Like the Active control, this is a "soft" switch so you can A/B the effect. The gate processing is applied to the wet / reverb signal only.
Smoothing - Sets how fast the gate processing responds to changes in the input signal. Lower settings correspond to a fast response time, whereas higher settings introduce a lag or damping effect to the responsiveness of the gate. Note that the smoothing time also affects the Attack and Release times, so if you need a really slow attack, try increasing the Smoothing too.
Threshold - Sets the signal level required to "open" the gate. Note - If set too high, you might not hear any reverb at all, and if set too low, no gating effect will occur as the signal will be loud enough to keep the gate open all the time.
Attack - Sets how quickly the gate opens once triggered. At the zero setting, the gate will open immediately, otherwise it opens up gradually, which can be used to create a swell / pseudo-reverse reverb effect. Sometimes, just having a little bit of a swell prevents the reverb from masking the attack of the dry signal which helps retain clarity. Alternatively, ramp-up the attack for spooky vocal effects!
Release - Sets how quickly the gate closes after the attack stage. At zero, it will close very quickly, depending on the Response settings. Longer release times can be quite subtle and allows for some fine-tuning of the reverb tail. Somewhere in the middle is the classic 80's drum type gated reverb effect.
