Creating or Separating Stereo Pairs

Although stereo pairs are meant to be used for intrinsically stereo audio like music or stereo sound effects, any two clips of audio in the Timeline can be made into a stereo pair or separated into two mono clips. This operation can only be performed in the Timeline.

Note: Stereo pair linking is not the same as clip item linking. It is not necessary to break the link between clip items prior to disabling stereo pairing.

To create a stereo pair
  1. Select a pair of mono audio clip items in the Timeline. (Use the Command key to select the second item, if necessary.) If you click one item of a linked pair, the other item is also selected.

  2. Choose Modify > Stereo Pair (or press Option-L).

    The stereo pair indicators appear on the selected clip items in the Timeline.

    If the clip items you want to make into a stereo pair have different durations, the clip items are trimmed to the region where they both overlap. The levels, pan settings, and filters that were applied to the top clip are applied to both, and the clip attributes from the bottom clip are ignored.

To separate a stereo pair
  1. Select a stereo clip item.

  2. Choose Modify > Stereo Pair, so that there’s no checkmark next to the menu item (or press Option-L).
