Channel EQ overview in Logic Pro for Mac
Channel EQ is a versatile multiband EQ. It provides eight color-coded frequency bands, including lowpass and highpass filters, low and high shelving filters, and four flexible parametric bands. It also features a Fast Fourier Transform (FFT) Analyzer that shows real-time changes to the frequency curve, allowing you to see which parts of the frequency spectrum may need adjustment. See Channel EQ parameters.
You can use Channel EQ to shape the sound of individual tracks or audio files or for tone-shaping on an overall project mix. The Analyzer and graphic controls make it easy to view and change the audio signal in real time.
Tip: The parameters of Channel EQ and Linear Phase EQ are identical, enabling you to freely copy settings between them. If you replace a Channel EQ with a Linear Phase EQ (or vice versa) in the same effect slot, the current settings are automatically transferred to the new EQ.
To add Channel EQ to your project, do one of the following:
Click the EQ overview on a channel strip.
Choose Equalizers > Channel EQ in a channel strip Audio Effect plug-in menu. See Add, remove, move, and copy plug-ins in Logic Pro for Mac.
Use the Channel EQ graphic display
The graphic display shows the current curve of each EQ band. The scale is shown in decibels. The color of each band matches the corresponding button above the display. Each band (and corresponding Frequency, Gain, and Q field) is highlighted as you move the pointer across it.
Click a curve line segment, the (center frequency) control point, or anywhere in the space between the zero line and EQ curve to adjust the band.
Click the control point to select a band for editing. Once a band is selected, no other band control point that falls within the active area of the selected band can be selected.
Click the graphic display background (outside a band) to deselect the selected band.
Hold down Command while performing any of the following operations to limit dragging to vertical or horizontal movement.
Drag anywhere in the band to adjust gain and the center frequency.
Drag the vertical lines that encompass the selected band to adjust the Q (bandwidth) only. Two arrow icons are shown.
Use a two-finger vertical swipe with the trackpad, or a single-finger vertical swipe with the Magic Mouse, to adjust the Q value of the selected band.
Drag the horizontal line in the selected band to adjust the gain only. If Q-Coupling is enabled, both the gain and bandwidth are adjusted. Two arrow icons are shown.
Drag the intersection of vertical and horizontal lines in the selected band to adjust the gain and Q simultaneously. Four arrow icons are shown.
Drag the control point to adjust the center frequency only.
Note: Horizontally dragging the control point in band 1 and band 8 adjusts both the frequency and Q.
Hold down Option-Command to adjust the Q and center frequency simultaneously. A “Q” icon is shown at the pointer position.
