Migration Notes
Known Issues

  • UI-270 Fixed: It is now possible to build in non-Unity mode.

Unreal Engine 4.9 - Wwise v2015.1.2

  • UI-249 Fixed: Avoid crashing when no Audio Playback device is available on Windows.

  • Added support for the Mac Editor.
  • Added support for the Mac platform.
  • Added support for the iOS platform.
  • Added support for the Linux platform.

Unreal Engine 4.8 - Wwise v2015.1

  • Migrated the UE4.8 integration to Wwise 2015.1
  • Fixed a crash on Xbox One if the app manifest did not contain a definition for Wwise communication ports.

Unreal Engine 4.8 - Wwise v2014.1.5

  • UI-206 Fixed: Sounds with an attenuation can now be heard when an animation window is opened.
  • UI-212 Fixed: Added a "Load Init Bank" Blueprint node.
  • UI-213 Fixed: Added null checks in Blueprint nodes, preventing crashes.

  • UI-223 Fixed: The gathering of the max attenuations for AkEvent does not halt when the parsing of one SoundBank fails.
  • UI-226 Fixed: SoundBank generation is now performed by the 32-bit WwiseCLI.exe when the 64-bit WwiseCLI.exe is missing.
  • UI-230 Fixed: Now using OnComponentDestroyed instead of FinishDestroy to unregister Wwise Game Objects, which had caused some Game Objects to be registered for too long.
  • UI-233 Fixed: Added validity checks on actors in the GetGameObjectID function.
  • UI-234 Fixed: Multiple viewports in the SetListener function are properly handled. This fixes a crash in AkAudioDevice.cpp.

  • UI-195 Fixed: Added blueprint_actor_posteventbyname, features_blueprintcsoundbanks_loadbyname, and Unload Bank Blueprint nodes.
  • UI-196 Fixed: Added a configuration parameter for the maximum number of concurrent Reverb Volumes applied on a sound.
  • UI-201 Fixed: Added an UAkAudioEvent to AkComponent, to bring it in sync with Unreal's AudioComponent. An AkComponent can by added in a Blueprint via drag & drop of a UAkAudioEvent. An actor with an attached AkComponent will also show its attenuation radius in the Editor.
  • UI-204 Fixed: Added code to unload auto-loaded SoundBanks.
  • UI-205 Fixed: Don't post events in a world that does not allow audio playback.

July 2014 - Wwise v2013.2.9

  • Added a SwitchDemo map to the UnrealWwiseDemo sample game, demonstrating the use of switches.

  • UI-152 Fixed: Add SoundBanks and streamed files to the packaging process.

April 2014 - Wwise v2013.2.7

  • UI-149 Fixed: Set proper default values for AkReverbVolumes.

March 2014 - Wwise v2013.2.6

  • Visual Studio 2013 is now used by default. Please refer to the Requirements page for more details.
  • UI-146 Fixed: Fixed non-unity build compilation errors.
  • UI-147 Fixed:
    • Verify the SoundEngine is initialized in the AkComponent tick function;
    • Properly set the collision channel name for AkReverbVolumes;
    • Avoid loading banks in a commandlet;
    • Removed the automatic bank creation mechanism.
  • UI-148 Fixed: Use "Get Player Controller" in the RTPCDemo Blueprint to ensure sound keeps playing when transitioning between "Simulate" and "Possess" modes in Editor.

January 2014 - Wwise v2013.2.5

  • Added an example of AkAnimNotify in ShooterGame. It is located in the FPP_RifleReload animation.
  • UI-131 Fixed: Spatialized sounds are now audible in the Animation Editor: Added a second listener for the Animation Editor window, and routed game objects created in this window to the new listener. WARNING: This fix changes the AnimNotify_AkEvent Blueprint. If you have made modifications to it, be sure to keep a backup before merging this integration.
  • UI-134 Fixed: Removed the input flag StopWhenOwnerDestroyed to GetAkComponent. It was unused and could create confusion. Added a SetStopWhenOwnerDestroyed method to the AkComponent.

  • UI-139 Fixed: Removed FMath::Abs on Z projection when setting listener position in SoundEngine (Unreal code has been left untouched). This allows upside down listeners.
