# Managing the Synchronization of Stereo Channels

If you are doing work that affects the media of a stereo track, you can disable the stereo sync from the left and right channels and modify only one channel. For example, there may be instances when you need to adjust the gain of one channel. You can remove the stereo sync to do the following to one channel of a stereo track:

- Applying and deleting soft effects
- Slipping a channel
- Replacing a segment’s source

If you applied the same soft effects to unsynced channels but the soft effect settings are different, you can resynchronize the settings.

To remove the stereo sync between the channels of a stereo track:

1. Click the Stereo Sync icon.

   The icon turns black indicating that the stereo sync for the channels has been disabled. You can now edit the media of one stereo channel without affecting the other channel.

   (a) Stereo sync disabled

   If you add a soft effect to an unsynced channel, a red bar appears indicating that the channels are not in stereo sync, and the indicator on the soft effect button turns red.

   (a) Gain soft effect applied to only one channel of a stereo track (b) Stereo channels are not in sync

To resynchronize a soft effect between stereo channels:

1. Select the stereo channels or elements containing the soft effects that you want to synchronize.
2. If there is more than one soft effect on your timeline selection but you only want to resynchronize one type, select the applicable soft effect icon on the timeline.
3. Select Resync FX from the Commit Effect box.
   NoteThis option is only available with stereo tracks.
4. From the message that appears, select whether you want to modify the soft effects on the left channel or the right channel.

   The same soft effect settings are applied to each channel based on your selection and the red bar is removed from the channel.

   NoteResynchronizing soft effects does not re-enable the stereo sync icon.

To re-enable the stereo sync icon between the channels of a stereo track:

1. Click the black Stereo Sync icon.

   The icon turns white indicating that the stereo sync between the channels has been re-enabled. If you had applied a soft effect to one of the stereo channels when the stereo sync was removed, the red bar remains on the channel and the indicator on the soft effect button remains red.
