Wwise SDK 2022.1.18
Release Notes 2017.2

The following sections list and describe the changes to Wwise between version 2017.1 and version 2017.2. For earlier versions, please refer to Previous Release Notes. If using the online help, you can also choose a different Wwise version from the list on top of the table of contents column.

Note: Plug-in Developers This version of Wwise supports plug-ins built with Wwise 2017.1 to Wwise 2017.2. For plug-ins built with older versions of Wwise, their developers must recompile and repackage them with a compatible version.

Platform SDK Changes

  • Switch SDK: Updated SDK to 3.5.1.
  • Android: Changed Android minimum required SDK level from API 9 to API 14 for 32-bit applications. Also, renamed Android library folders to remove the unnecessary API level in the folder name. Therefore, the library directories for Android have changed as follows:
    • SDK\android-9_armeabi-v7a > SDK\Android_armeabi-v7a
    • SDK\android-9_x86 > SDK\Android_x86
    • SDK\android-21_arm64-v8a > SDK\Android_arm64-v8a
    • SDK\android-21_x86_64 > SDK\Android_x86_64

New Features

  • WG-32391 Added new profiling warning (in the Capture Log) when the number of Resume and/or Play-From-Beginning virtual voices exceeds a per-project limit.
  • WG-32758 Extended State system to most properties that support RTPCs - both Wwise objects and plug-ins.
  • WG-32999 Added tab delimited file import of localized voice assets from WwiseCLI.
  • WG-33396 Added built-in parameter Listener Cone and renamed "Object to Listener Angle" to Emitter Cone.
  • WG-33758 Breaking change! Unified Motion feature set with audio feature set. Motion devices are now considered ordinary Audio Devices and Secondary Outputs. Read more about the impact of this feature change on your game in Breaking changes in motion support.
  • WG-33884 Added support for new spread settings in SCE Audio3d.
  • WG-34123 Set the first curve as the default selection in the Property Editor's RTPC tab.
  • WG-34174 Added Output Bus Volume, Output Bus LPF, and Output Bus HPF controls onto busses, allowing one to filter the output of mixing busses using built-in LPF/HPF.
  • WG-34198 Overhauled Rooms and Portals (introduced in 2017.1) into a complete solution for modeling sound propagation. Refer to Rooms and Portals for more details.
  • WG-34209 Added version of the SDK and the banks "Load bank failed" error message now specifies the version of the SDK and the banks for easier troubleshooting.
  • WG-34473 Added input, output, and gain reduction meters to the Wwise Compressor plug-in.
  • WG-34650 Breaking change! Simplified Secondary Output management. Secondary Outputs are now exposed in the authoring application through the Audio Device property on Master Busses. And iIt is now possible to add as many Master Busses as needed in the Master Mixer Hierarchy. Read more about the impact of this feature on your game here: Breaking changes in audio output management, secondary outputs, and sink plug-ins.
  • WG-35243 Added collapse and expand of Mixing Desk sections.
  • WG-35313 Improved Shift+X (Show Source Editor) shortcut to automatically show the current selection in the Source Editor.

Refer to New Features Overview 2017.2 for more new features and details.

API Changes

  • WG-34172 Normalized most plug-in names. For example, AudioInput is now AkAudioInput, Sine is AkSineTone, and ToneGen is AkToneGen.
  • WG-34172 Added the Source suffix to source plug-in libraries. For example, AkSynthOne is now AkSynthOneSource.
  • WG-34172 The Visual Studio property sheets for Authoring plug-ins have been renamed from PropertySheets\AuthoringRelease.props to PropertySheets\Win32\NDebug_vc120Auth.props, and from PropertySheets\AuthoringDebug.props to PropertySheets\Win32\Debug_vc120Auth.props.
  • WG-34198 Overhauled Spatial Audio:
  • WG-34337 As part of the Motion refactoring, removed the following:
    • The function AK::SoundEngine::SetListenerPipeline
    • The class IAkMotionMixBus
    • And the namespace AK::MotionEngine, which included the functions AddPlayerMotionDevice, RemovePlayerMotionDevice, SetPlayerListener, and SetPlayerVolume.
  • WG-34541 The AkReflectImageSource struct was modified such that its fields were moved into sub-structures AkImageSourceParams, AkImageSourceTexture and AkImageSourceName.
  • WG-34650 As part of the Output Management refactoring, renamed AddSecondaryOutput and RemoveSecondaryOutput to AddOutput and RemoveOutput, with different parameters. GetSpeakerConfiguration, GetPanningRule, SetPanningRule, GetSpeakerAngles, GetSpeakerAngles, and SetSpeakerAngles changed parameters. Removed idAudioDevice from AkPlatformInitSettings and replaced it by AkOutputSettings.idDevice in AkInitSettings. AkAudioOutputType was removed entirely. See Breaking changes in audio output management, secondary outputs, and sink plug-ins for more information.
