Chapter 9 Mixing Surround Sound 309
Placing Dialogue and Voiceover in a Surround Mix
In a surround mix, dialogue usually goes directly into the center channel. This is
particularly true for voiceover narration, which is best left out of the left and right
channels. (This is called stereo plus center.) Soundtrack Pro allows you to place sounds
exclusively in a specific channel or just outside that channel, which would allow some
of the sound to leak into the other speakers. As you get more comfortable with
surround mixing, you may want to experiment with alternative placements to further
reinforce the voices that you place within your mix.
To place dialogue and narration in the center channel:
1 If you haven’t already done so, Control-click the stereo pan slider in the track header of
the dialogue track (or bus), then choose Use Surround Panner from the shortcut menu.
2 Double-click the surround panner.
The Surround Panner HUD appears.
3 Drag the puck to the center speaker icon.
Depending on the current Collapse slider setting, the arc at the center speaker icon either
turns white to indicate exclusive output or is elongated to indicate the increased gain.
Note: You can hold down the Option key as you drag the puck to constrain its
movement to a straight line.
