cineSync Play supports separate audio tracks, and there are several ways how you can also add the audio track together with your media file.
You can add them from the lower-left corner of the player interface.
Or from the ‘Playlist’ menu, choosing the ‘Add Media +Audio…’.
Plus, you can also use the keyboard shortcut keys.
Once selected, this will take you to a new window where you can add your Media and Audio files.
If you need to synchronize your audio, you can do it using the ‘Audio Synchronize’ feature from the ‘Tools’ menu or using the keyboard shortcut key.
Once enabled, you can modify the ‘Audio Offset’ either in Seconds or Frames, and you can choose to apply the setting to all files.
