Band-pass filter - free VST audio effect plug-in download for music production, broadcasting and general audio editing.
For more details, read through the online manual below.
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.
In GVST terms, this plug-in is identical to having a GLow and GHi running one after the other.
Each knob is laid out the same way for consistent and easy reference. Above each one, its function is labelled. Below each one is a numerical readout of the value assigned. One additional mini-window at the bottom of the GUI shows the peak level of the incoming signal, in decibels.
Gain: This knob adjusts the input (rather than output) level. On GBand, at least, the end result is identical either way. Surely a gain knob needs no further explanation!
Lo Cut: Only frequencies above this level will be allowed to pass through. Anything below is cut.
Hi Cut: Any remaining frequencies below this value (after the Lo Cut has already subtracted some) are passed through. Any frequencies higher than this knob's setting are cut.
Res: This knob sets the "resonance", for both filters. Resonance is created by boosting a small band of frequencies at the two filters' cut off points.
Peak Display: In addition to your usual methods of metering, this small window gives you a quick look (peek?) at how "hot" the output audio is. This is useful as resonance can create considerable peaks in the output.
