GHi Manual

Welcome to GHi

GHi is a resonant high-pass filter. It has three simple controls and one useful purpose. It filters out frequencies below a user-defined cut-off frequency, and adds variable amounts of resonance at that point.

Installation

  1. All GVST plug-ins come compressed in a ZIP file, so the first step is to extract the files from the ZIP file.
  2. Once extracted, you should have one or more DLL files, these are the plug-in files.
  3. You need to copy the plug-in files to the appropriate folder for your host program.
  4. In most cases, you will need either to restart the host program or re-scan the plug-in folder in order for newly-installed plug-ins to appear.

Hints

  • Automating the "Cut Off" and "Res" (resonance) knobs can add drama to an individual track, a sub-mix, or entire segments of a song at mix-down.
  • With a 0% resonance setting, GHi can be used to restrict the frequency range an instrument or track occupies, without colouring the sound.
  • Because resonance can add substantial peaks to an audio signal, keep an eye on the "Peak" window to help control the changes being made.

Interface

GHi user interface

The three knobs are presented the same way for consistent and easy identification. Above the knob, its function is labelled. Below the knob, a numerical readout reflects the user adjustments or allows the user to manually specify values. One additional mini-window at the bottom of the GUI shows the peak level of the outgoing signal, in decibels.

Gain: This knob adjusts the level of the incoming signal, pre- processing.

Cut Off: Only frequencies above this point will be allowed to pass through.

Res: This knob sets the "resonance", for the filter. Resonance is created by boosting a small band of frequencies at the filter's cut off point.

Peak Display: As a supplement to your existing metering methods, GHi will display the peak level it has passed. Click this mini-window to reset the readout.
