• Gain/Slope control: Drag to set the amount of gain for the selected band. For bands 1
and 8, this changes the slope of the filter.
• Q control: Drag to set the Q factor or resonance of the effected range around the center
frequency in the selected band.
Note: The Q parameter of band 1 and band 8 has no effect when the slope is set to
6 decibels per octave. When the Q parameter is set to an extremely high value, such
as 100, these filters affect only a very narrow frequency band and can be used as
notch filters.
• Analyzer Range display: Drag vertically to adjust the scaling of the Analyzer range.
Control-click to open a shortcut menu where you can set the Analyzer Range value.
• Scale display: Drag vertically to adjust the scaling of the overall EQ curve. Control-click
to open a shortcut menu where you can set the EQ dB Scale Mode.
• Master Gain slider and field: Set the overall output level of the signal. Use it after
boosting or cutting individual frequency bands.
• Analyzer button: Turn the Analyzer on or off. Play the audio signal and watch the
graphic display to identify peaks and troughs in the frequency spectrum. Control-click
to open a shortcut menu where you can set Analyzer Mode and Analyzer Resolution.
See Linear Phase EQ shortcut menus, Logic Pro
Linear Phase EQ Analyzer, and
Logic Pro Linear Phase EQ extended parameters.
• Analyzer (Pre/Post) button: Set to display the frequency curve before or after EQ is
applied, when Analyzer mode is active.
• Q-Couple button: Turn on Gain-Q coupling, which automatically adjusts the Q when you
raise or lower the gain on any EQ band. This preserves the perceived bandwidth of the
bell curve. Control-click to open a shortcut menu to set the Gain-Q Couple Strength
value. See Linear Phase EQ shortcut menus.
• Processing pop-up menu: Choose to process both sides of a stereo signal, or the Left
Only, Right Only, Mid Only, or Side Only signal. See Logic Pro
Linear Phase EQ use tips
for information about using Linear Phase EQ with Mid-Side recordings.
