3D Object Panner parameters in Logic Pro for Mac

3D Object Panner window

Although you can position the pan puck using the 3D Object Panner control of the channel strip or track header, you can access more parameters and controls when you open its corresponding 3D Object Panner window.

Click the Link button  to update the window showing the pan control of the currently selected track. You can also open multiple 3D Object Panner windows simultaneously (to show the settings of multiple object tracks) and save them in screensets.

The 3D Object Panner window contains two grids. Change the position of the puck in the upper grid to move the object left, right, front, and back. Change the position of the puck in the lower grid to move the object left, right, up, and down. Mono objects are represented by a single pan puck. Stereo objects are represented by three pan pucks: a puck for the left (L) signal, a puck for the right (R) signal, and a third puck (a dot) that represents the middle of the stereo image and controls both the L and R pucks as a group. Stereo objects also have a Spread parameter that controls the stereo width of the signal.

Although both the Surround Panner and the 3D Object Panner can route an audio signal in the three-dimensional sound field, the 3D Object Panner has some significant differences:

  • Creating a pan position generates metadata that is sent separately from the audio signal to the same corresponding object input of the Dolby Atmos plug-in.

  • The three-dimensional position where you place the signal with the pan puck has no reference to a specific speaker setup and is only referenced to a XYZ coordinate in the three-dimensional space.

  • There is no option to route the signal to the LFE channel.

  • The 3D Object Panner can’t be used on surround tracks, only on mono tracks or stereo tracks.

Open the 3D Object Panner window

In Logic Pro, do one of the following:

  • Double-click the pan control on the channel strip.

  • Double-click the pan control on the track header.

Control the position, size, and width of the 3D object

In the Logic Pro 3D Object Panner window, do any of the following:

  • Change the position by dragging the puck, the green dot representing the position of the audio signal.

    • Drag the puck in the upper grid to move the object left, right, front, and back.

    • Drag the puck in the lower grid to move the object up, down, left, and right.

    • On a stereo track, drag the L puck and R puck to change the spread of a stereo signal.

    • On a stereo track, drag the L puck or R puck across the pan puck to swap the left and right channels of the stereo signal.

  • Change the individual values by dragging them up and down, or double-click on a number and enter a value numerically.

    • Left/Right: Controls the position of the object track on the left–right axis in 3D space.

      Move the puck left or right. A value of 0 indicates the center position, -1 is far left , and +1 is far right.

    • Back/Front: Controls the position of the object track on the front–back axis in 3D space.

      Move the puck to the front or back. A value of +1 indicates the front position, -1 is the back position, and 0 is the position of the listener in the center.

    • Elevation: Controls the position of the object track on the vertical axis in 3D space.

      Move the puck up or down. A value of 0 indicates the ear-level position, and +1 is the ceiling position.

    • Size: Changes how the signal of the object track is perceived with regard to its precise location in 3D space. Increasing the value results in a more diffuse image of the actual sound source.

      The size is visualized by a halo around the puck.

    • Spread: Controls the width of the stereo signal in 3D space. This parameter is available only for stereo tracks.

You can record and edit parameter changes in the 3D Object Panner as automation curves. See Overview of automation.
