Resumo de Recurso

Slide 1

    EQ Parameters
    EQ (equalisation) is a very common plugin which affects the levels of different frequencies ranges in an input signal. This is normally presented in a visual formal, with multiple different curves and shelves to produce the resultant curve desired.
    Rubrica: : Logic's graphic equaliser plugin

Slide 2

    Gain
    In an EQ plugin, there is a gain setting for each curve or shelf, and one gain setting for a flat boost or reduction of the entire signal.
    Rubrica: : Two EQ curves on the default Logic Pro Channel EQ plugin, showing a boosted frequency curve and a reduced frequency curve on the left and right respectively

Slide 3

    Frequency
    For each band, the centre point for the curve, or start point for the shelf is determined by the frequency parameter.Basic EQs come only with 'high', 'mid', and 'low' parameters to change the gain of. With parametric or graphic EQs, the centre frequency can be set for each.
    Rubrica: : An EQ graph showing a single curve boost

Slide 4

    Q
    Yes, just 'Q'.This is the parameter which changes the slope of the curve on a boost or shelf, and affects how much the neighbouring frequencies of the centre of the curve are changed by the curve. It is also referred to as the bandwidth, but can be bunched in with the 'slope' setting as one, as it is in Logic Pro's EQ plugin.
    Rubrica: : A single band with a steep slope and thus narrow range of effect

Slide 5

    Types of EQ Curve
    There are multiple different kinds of curve within an EQ plugin that are used to affect the frequency range.These include: Single band Shelf Cutoff Rolloff
    Rubrica: : Rolloff at 138Hz, single band gain at 356Hz, high shelf at 2450Hz
