  • WG-22147 Removed the -autoclose and -hideprogressui arguments from the Copy Streamed File application. Now the copy streamed file application is always command line.

  • WG-23308 Channel names are now shown in the Source Editor.
  • WG-23413 The Output Bus can be to be linked/unlinked to a Platform.

API Changes

  • WG-23042 Added output channel configuration to AkSpeakerVolumeMatrixCallbackInfo; also renamed input configuration to uInputConfig (formerly uChannelMask).
  • WG-23169 Added the language code (in_szLanguageCode) to the Help function in AK::Wwise::IAudioPlugin.
  • WG-23170 Added virtual GetUndoManager() function to IPluginPropertySet. This enables plug-ins to access the undo system.
  • WG-23240 You can now specify the listener bitmask in RegisterGameObj.
  • WG-23256 Added function OnPluginMediaChanged() to AK::Wwise::IAudioPlugin.
  • WG-23422 Speaker angles can now be specified using SetSpeakerAngles().
  • WG-23503 (Android) expose OpenSL pointer in the SDK (AkPlatformInitSettings)
  • WG-22480 (iOS) Added platform settings to handle audio behaviours for background-foreground switching and inter-app mixing.
  • WG-23561 (iOS) Fixed profiler reconnection failure after the suspend-wakeup UI sequence. Added new API to reinitialize communication module using current settings.

Behavior Changes

  • WG-16917 Follow Capture Time is now automatically enabled when starting a capture.
  • WG-23144 "Default" bus channel configuration property has been replaced by "Parent". The former value used to mean "hardware device configuration", while "Parent" means "parent bus configuration". The resulting configuration of "Parent" buses may therefore be different with this new version.
  • WG-23043 Downmix equations have been made compliant with AC3 standards. This may result in slight changes in your mix when downmixing from different channel configurations.
  • WG-22922 3D objects are panned according to the channel configuration of the bus into which they are mixed. This means that 3D objects panned into a stereo bus sound with the same volume whether they are in the front or in the back, while they previously sounded 3 dB lower due to the standard downmix recipe where surround channels are attenuated by 3 dB.

Performance Changes

  • WG-22992 Performance improvement when updating massive number of RTPC values at every game frame.
  • WG-23404 Reduced memory usage in Default Pool.
  • WG-23423 (Unity) Performance improvement in Unity integration with game object calls.
