GHi is a resonant high-pass filter.It has three simple controls and one useful purpose. It filters out frequencies above a user-defined cut-off frequency, and adds variable amounts of resonance at that point. Gain. Cut Off. Res. Peak Display.
GGrain is a granular resynthesizer. It breaks down the incoming signal into grains and then reassembles it. A grain is just a very short section of the sound, shaped to avoid clicks. You can specify the number and size of the grains taken from the incoming signal. The level and pitch of each grain can then be altered before the sound is reconstructed, giving a variety of interesting effects.
GGate is a noise gate which silences the incoming signal once it drops below a user-defined threshold. This kind of effect is useful when source material contains background noise during "silent" passages, such as the hum of an amplifier or artefacts from an effect chain. The main portion of the source audio is usually significantly louder than this background noise, so when GGate receives an appropriate boost in amplitude, it knows that it's time to let the signal pass through.
GDuckDly is a digital delay. It allows the wet signal to be compressed by the dry signal. The GUI features seven knobs and a switch that control all of GDuckDly's parameters. There is also a gain reduction meter. Delay. Feedback. Feedback Post-Compressor. Attack, Release and Amount. Dry and Effect.
It takes an incoming audio stream, splits it in two, detunes one stream by a user-defined amount, which also oscillates between being in and out of tune, and then blends the two back together again. The effect can be thought of as adding a second performance of the material. The detuning of the second performance mimics the slight discrepancies in pitch and timing that would be present if two people were to perform the same piece.
GBand is a resonant band-pass filter. A typical band-pass filter is configured by selecting a central frequency "node" and adjusting the Q (width) of the band surrounding the node. GBand operates in a much more intuitive way. It is actually composed of a low-cut and a high-cut filter operating in series. В In GVST terms, this plug-in is identical to having a GLow and GHi running one after the other.
