The Complete Guide to SLATE

Audio Track

The Audio Track obviously works very closely with Audio Clips, and is possible to process audio clips without the need for you to have an Audio Source on the target Actor. The Audio Track has few, but important settings which can be set in its inspector panel to control how audio clips in this track are played.


  • Name is simply the display name within the editor for personal organization.
  • Output Mixer. All Audio Clips played within the track, will be sent to the selected Audio Mixer, which gives you control over your audio using the new Unity’s powerful audio system. This is of course optional.
  • Master Volume. All audio Clips in this track will be modulated based on the track’s Master Volume setting. A value of 0 to 1.
  • Spatial Blend. This setting controls whether or not the audio clips played by this track will be 2D or 3D and how much. A value of zero means full 2D while a value of one means full 3D. Please note that an AudioTrack within the DirectorGroup always plays 2D audio.
  • Stereo Pan. The stereo side at which audio clips of this track will play. A value of -1 to 1 for left to right respectively.


Audio Clips set to be played in the Audio Track, are able to be trimmed or be looped simply by setting the clip to the desired length. Furthermore, as with most ActionClips in SLATE, the blend in/out properties in this case control the fade in/out that the audio will have.



The Audio Action Clips are also able to have subtitles text that will be shown on screen to go along with them, which makes more sense in the context of an Audio Clip played within an Actor Group, although it’s quite possible in the Director Group as well.



Audio pitch is also modulated by the current time of the game. As such if you alter the time for a slow-motion or fast motion effect, the audio will automatically follow along.


Finally, remember that splitting the clip will retain its offset correctly, thus it’s possible to split a big dialogue audio or maybe music, into small partial clips.
