The following sections list and describe the changes to Wwise between version 2019.2.5 and version 2019.2.6.
Platform-specific information can be found here:

For earlier versions, please refer to Previous Release Notes.

New Features

  • WG-48759 Added two new global callbacks: AkGlobalCallbackLocation_Suspend and AkGlobalCallbackLocation_WakeupFromSuspend.
  • WG-50146 Added a new audio session category to the iOS PlatformInitSettings, AkAudioSessionCategoryPlayback.
  • WG-50604 A profiling filter bar was added to the RTPC tab in Property Editor and various other editors.

Behavior Changes

  • WG-50461 SetGameObjectAuxSendValues, SetGameObjectOutputBusVolume, SetMultipleObstructionAndOcclusion now clamp input values between 0 and 1.
  • Exceptionally for 2019.2.6, it is not possible to connect Wwise Authoring to a previous minor version of the sound engine.

Performance Changes

  • WG-47937 Significantly improved performance of Wwise Convolution when processing silent input audio, including reverb tails. A new setting for Wwise Convolution sharesets, "Input Thresh", has also been added, to allow for discarding high-frequency input audio below the specified volume, which can reduce convolution processing even further.
  • WG-49532 Improved performance and memory usage of Game Profiler when capturing.
  • WG-50517 Improved performance and lowered memory usage when profiling in the Game Sync Monitor with Voice Inspector Data enabled.

Bug Fixes

  • WG-46457 Fixed: The camera list in the Game Object 3D Viewer contains duplicate entries.
  • WG-47032 Fixed: Running multiple instances of WwiseConsole simultaneously could result in file conversion failure.
  • WG-47776 Fixed: Busses with States on BusVolume may incorrectly apply volume changes to child busses. In such cases, the volume change is applied to the child bus's BusVolume, as opposed to its OutputBusVolume.
  • WG-48729 Fixed: Occasional crash in Voice Inspector when moving the profiler cursor.
  • WG-49826 Fixed: Copying a transition within a Music Switch Container doesn't copy its source and destination.
  • WG-49993 Fixed: Transitions are not properly reported by the Voice Inspector when a game object is destroyed during a transition.
  • WG-50097 Fixed: Wwise Pitch Shifter plug-in input not displayed correctly.
  • WG-50164 Fixed: Spatial Audio Room reverb tails and early reflection tails are truncated when a single short sound is played on an emitter game object behind a portal, after the listener moves.
  • WG-50229 Fixed: The "On return to physical voice" check box was erroneously grayed out in the virtual voices options when the "Virtual voice behavior" was set to "kill if finite else virtual".
  • WG-50260 Fixed: Spatial Audio diffraction angles close to 180 degrees result in 0% diffraction.
  • WG-50378 Fixed: Spatial Audio: Low memory crash when allocating internal data structures.
  • WG-50399 Fixed: Slow leak when running Profile or Debug versions of the sound engine when using Spatial Audio features without authoring connected to the game.
  • WG-50415 Fixed: Filtering in Game Sync Monitor is not working as expected.
  • WG-50506 Fixed stuttering when MS Spatial driver failed.
  • WG-50508 Fixed: The PluginName field in the work unit's XML is lost when using the navigator buttons in the Effects list.
  • WG-50510 Fixed: RTPC on Game Aux Send Value and User Aux Send Value are not clamped, resulting in out-of-range audio samples.
  • WG-50511 Fixed: Crash when attempting to write in a folder for which the user does not have permissions.
  • WG-50514 Fixed: Crash when dragging objects from the Voices tab of the Advanced Profiler.

  • WG-50672 Fixed: ActionSetState and ActionSetSwitch in the SoundBanksInfo.xsd Schema are inverted.
  • WG-50691 Fixed: Actuator Configuration in Motion Source plug-in does not properly respect platform linkages.
  • WG-50732 Fixed: Freeze when generating banks into a directory where the user does not have write access.
  • WG-50758 Fixed: RTPC tab of Actor-Mixer hierarchy objects shows unrelated game object values during capture.
