Use Logic Pro Channel EQ shortcut menus
The Analyzer and Q-Couple buttons provide additional parameters that you can use to
enhance the behavior of Channel EQ.
Control-click the Analyzer or Q-Couple button to open a context menu that contains the
following parameters.
Analyzer
• Analyzer Mode: Choose Peak or RMS.
• Analyzer Resolution: Choose a sample resolution for the Analyzer: Resolution low
(2048 points), Resolution medium (4096 points), or Resolution high (8192 points).
Gain-Q Couple Strength
Choose the amount of Gain-Q coupling.
• Proportional: Scales the bandwidth proportionally as you change the gain. A
proportional Q design widens the filter bandwidth at lower cut/boost levels and
narrows it at higher settings.
• Light or medium: Allows some change as you raise or lower the gain.
• Strong: Preserves most of the perceived bandwidth.
• Asymmetric: These settings feature a stronger coupling for negative gain values than
for positive values, so the perceived bandwidth is more closely preserved when you
cut, rather than boost, gain.
Note:
If you play back automation of the Q parameter with a different Gain-Q Couple
Strength setting, the actual Q values are different than when the automation was
recorded.
Logic Pro Channel EQ extended parameters
Click the disclosure triangle at the lower left to display the extended parameters.
• Analyzer Decay slider and field: Set the decay rate (in dB per second) of the Analyzer
curve. These are shown as a peak decay in Peak mode or an averaged decay in
RMS mode.
Logic Pro Channel EQ use tips
The way you use Channel EQ depends on the audio material and your intended outcome.
A useful workflow for many situations is as follows: Set the Channel EQ to a flat response
(no frequencies boosted or cut), turn on the Analyzer, and play the audio signal. Watch
the graphic display to see which parts of the frequency spectrum have frequent peaks
and which parts of the spectrum stay at a low level. Pay attention to sections where
the signal distorts or clips. Use the graphic display or parameter controls to adjust
the frequency bands.
