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 Linear Phase 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. This is shown as a peak decay in Peak mode or an averaged decay in RMS mode.
Logic Pro Linear Phase EQ use tips
Linear Phase EQ is typically used as a mastering tool that is inserted into master or
output channel strips. The way you use Linear Phase EQ depends on the audio material
and your intended outcome. A useful workflow for many situations is as follows: Set
Linear Phase EQ to a flat response (no frequencies boosted or cut), turn on the Analyzer,
then 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.
You can reduce or eliminate unwanted frequencies and you can raise quieter frequencies to
make them more pronounced. You can adjust the center frequencies of bands 2 through 7
to affect a specific frequency—either one you want to emphasize, such as the root note of
the music, or one you want to eliminate, such as hum or other noise. Use the Q parameter
or parameters so that only a narrow range of frequencies is affected.
You can adjust the decibel scale of the graphic display by vertically dragging either the left
or right edge of the dB scale when the Analyzer is not active. When the Analyzer is active,
dragging the left edge adjusts the Analyzer dB scale, and dragging the right edge adjusts
the linear dB scale.
To increase the resolution of the EQ curve display in the area around the zero line, drag the
left side of the dB scale upward. Drag downward to decrease the resolution.
