Graham Yeadon Ghi

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. HintsAutomating 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 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.
