The parametric values of filters are displayed in the Inspector window. They deal with their time/frequency coordinates and behaviour. To edit a parameter, double click in a prompt, type a value and press
The Edit Gain dialogue window allows the edition of the gain and contour of a selected filder. The same modifications can be executed via the Inspector window, with additional features.
To change the gain of a filter, enter a positive or negative value between -116 and 116 dB. Values beyond these limits are automatically limited, although it doesn't show in the Inspector.
The contour of the filter can be flat, or faded. To choose and option, click on the
With a fade, the gain peak within the filter is localized in the middle of the temporal segment represented by the filter. This position can be specified very precisely in the Peak Time prompt.
The three temporal parameters of surface filters – Start, End, Duration– can be edited independantly from each other. This means that the duration of a filter can be modified.
The Low and High frequencies of surface filters can also be modified.
Due to the irregularity of their graphic representation, others filters cannot have these parameters modified via the Inspector.
Region filters and both types of pencil stroke filters can have their time and frequency values modified manually from the sonogram window or processing sequencer.
Additionnaly, the frequency parameters of pencil strokes can also be modified undirectly through the
Pencil Stroke Settings menu, and the corresponding Pencil Stroke parameters of the Inspector – see below.
The parameters described in the
The Pen Width, Thickness and Harmonic Compensation Factor will modify the frequency band of each harmonic.
The Number of Harmonics, Parity – Odd or Even – and Base Harmonic parameters will affect the spectral characteristics of a harmonic pencil stroke filter.
Harmonics lists cannot be modified. Just as in with the settings window, harmonics lists prevail on modifications of the spectral contents parity of pencil strokes.
When several pencil strokes have been created, the modifications apply to the last selected item, even if several items have been selected at the same time.
