Logic Pro X: Channel EQ extended parameters
Click the disclosure triangle at the lower left to display the extended parameters.
Analyzer Resolution pop-up menu: Choose the sample resolution for the Analyzer. Choose from: Resolution low (2048 points),Resolution medium (4096 points), and Resolution high (8192 points).
Analyzer Mode buttons: Choose Peak or RMS.
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.
Gain-Q Couple Mode pop-up menu: Choose the amount of Gain-Q coupling.
Strong: Preserves most of the perceived bandwidth.
Light or medium: Allows some change as you raise or lower the gain.
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.
Proportional: Scales the bandwidth proportionally as you change the gain. A proportional Q design widens the filter bandwidth at lower boost/cut levels and narrows it at higher settings.
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.
