+=== Playback Limits
+
+Wwise has a limit on the amount of audio that can be played at once. 
+Trying to play more than this limit will result in lower priority sounds like footsteps, music or animal sounds will not play.
+
+To resolve this you will need to setup playback limits for each of your audio files. This can be done in the audios advanced settings tab.
+
+image:Satisfactory/Wwise/Wwise_PlaybackLimit.png[Wwise_PlaybackLimit, 700]
+
+You will need to set the `Limit sound instance to` amount, this is amount of instances that can play this audio on the AK Component in Unreal.
+Also set the dropdown next to this limit to `Per Game Object` this means per `AK Component` in unreal.
+
+Next you will need to change the `When limit is reached` to `Kill voice` and also set the drop down under that to `Discard oldest instances`.
+This means when the limit is reached for this audio it will kill any oldest instances and discard them.
+
+Finally you will need to setup playback priority. The playback priority requires that you have setup Attenuation.
+
+Set the priority of your audio to something like `10`, then set the `Offset priority by` setting to `-10`.
+
+This setting will set the audio priority to 10, then when you are outside the attenuation distance will set the priority to 0 allowing for more important audio like the game sounds to be played.
+
+Even with Attenuation and playback limits setup the audio will still play and count towards the Wwise Playback Limit.
+
+* Attenuation will only lower the volume of the audio and not stop the audio.
+* Playback limits are only limiting the number of audio instances playing on a game object.
+
+So to prevent audio from playing when you are outside of the attenuation range you will need to make use of the Significance Manager.
+
+For playing background buildings sounds use the `Gained Significance` and `Lost Significance` events:

+
+For fire and forget ak events use the `Get Is Significant` function before posting the event:
