Platform SDK Changes

  • Opus: Updated to version 1.3 of encoder and decoder library.
  • Switch SDK: Updated SDK to 7.3.0.
  • PS4 SDK: Updated SDK to 6.008.031.

New Features

  • WG-17193 Added the ability to trigger Events from Music Segments.
  • WG-34558 Added new Music Transition Destination options for Music Playlist Containers. Last Played Segment and Next Segment offer the possibility to resume a music playlist's playback between different Switch states of an ancestor Music Switch Container.
  • WG-35746 Improved the Project Explorer to allow copy and paste of an object onto itself in order to quickly duplicate it, instead of having to select the parent.
  • WG-36703 Created new shortcuts, Alt + , and Alt + ., to move to previous and next frames within Profiler views.
  • WG-36796 Added collapsible splitter to some views.
  • WG-37100 Added associated keyboard shortcut keys to button tooltips.
  • WG-37229 Refined double-click on property RTPC indicators to highlight the correct entry in the RTPC list.
  • WG-37690 Added setting for optimizing Spatial Audio calculations with respect to listener: AkSpatialAudioInitSettings.fMovementThreshold.
  • WG-37947 Added a new panel to the RTPC tab, which allows you to view and modify the selected RTPC's settings without opening its editor. The panel also has an icon which displays the number of references to the selected RTPC and which can be clicked to open the Reference View listing all the references.
  • WG-38148 (WAAPI) Added ak.wwise.core.object.setRandomizer function.
  • WG-38779 Set Wwise to save the last used layout and to automatically restore it after the project loads.
  • WG-38915 Changed Spatial Audio to permit issuing individual reflection and diffraction processing tasks to the game engine's job scheduler, allowing tasks to be executed in parallel across CPU cores and improving overall system efficiency by better utilizing available CPU resources.
  • WG-39165 Added shortcuts (Ctrl+Number and Ctrl+Alt+Number) to change tab selection in the Property Editor's alternate split.
  • WG-39203 Expanded keyboard navigation to have the Tab and Tab + Shift option work in the Project Explorer when editing an object name.

  • WG-39557 Created the new Logs view, which incorporates start-up, project load, SoundBank generation, conversion, and WAAPI messages. It replaces the Project Load Log and SoundBank Generation Log views.
  • WG-39825 (WAAPI) Added topic, which publishes the result of an import operation.
  • WG-39889 Added new "Enable Attenuation" RTPC-able property, which lets you control whether or not to apply the Attenuation ShareSet.
  • WG-40018 (WAAPI) Added ak.wwise.core.profiler.getVoices to allow retrieval of voice structures from the profiler in the authoring application.
  • WG-40019 Added distinct commands to start and stop the capture.
  • WG-40021 Replaced Hue by Color in the User Preferences and changed it from adjusting the skin hue to affecting only neutral grays, allowing to change the color of the user interface without affecting the skin color scheme.
  • WG-40054 Supplemented context menu for RTPC-able elements with Add RTPC option for direct RTPC creation.
  • WG-40218 Added new experimental Light theme for users who prefer a light skin over the dark one but want better contrast than the Classic theme. Because it's currently experimental, there may be items without the correct colors.
  • WG-40262 Created default keyboard shortcuts for Mute (Alt+M) and Solo (Alt+S).
  • WG-40274 Reorganized Source Editor view layout to maximize WAV file editing.
  • WG-40384 Enhanced Performance Monitor with an average curve. Set CPU and Plug-in timers to high-frequency resolution, with a default average curve roughly corresponding to the 200 ms sampling interval in prior releases.
  • WG-40422 Added drag & drop support for WAV files in SoundSeed Grain.
  • WG-40438 Added a "none" option to the SoundSeed Grain modulator list button to remove a modulator association from a given parameter.
  • WG-40546 Added Vorbis as a SoundSeed Grain Conversion Setting.

  • WG-37672 Stopping, pausing, and resuming a Play Action from within Wwise authoring now does so by playing ID. This has a direct effect on the behavior within the context of the Soundcaster. When playing a sound via multiple Soundcaster modules, a Pause, Resume, or Stop Action on an individual module will only affect the sound instances associated with that module.
  • WG-38218 Event Actions created through Tab Delimited Import will not be added to an existing Event if an identical one is already assigned.
  • WG-38720 When using ADPCM to encode a file during conversion, we now use the Platinum Games codec.
  • WG-39067 Command line messages are prefixed with the channel in which they were logged (when applicable).
  • WG-39435 The title bar has indicators to show the application is in automation mode or, if it is a debug build, has asserts disabled. If the automation mode is enabled, the skin colors will also be offset.
  • WG-39692 Improved the accuracy of sample accurate transitions when reacting to "break" actions.
  • WG-39787 The Randomizer Min Offset and Max Offset property display range is now based on the display range of the randomized property.
  • WG-39842 The dark skin is now used by default, replacing the classic skin.
  • WG-39899 (WAAPI) Functions and now return the list of log entries, which can be retrieved as an array through the log property of the details object, when there's an error. Additionally, now returns the list of imported objects on success.
  • WG-40053 The first row of an RTPC list is now only automatically selected if there is at least one RTPC set.
  • WG-40069 Copy-pasting items in the Project Explorer now automatically selects the pasted items.
  • WG-40073 (Android) Wwise will dynamically increase its internal buffer size to limit cases of voice starvation.
  • WG-40213 Wwise authoring blocks Windows from closing if your project is not properly saved or reverted.
  • WG-40240 Ctrl+Mouse Wheel now zooms vertically, while Ctrl+Shift+Mouse Wheel zooms horizontally.
  • WG-40572 When there are multiple SoundSeed Grain instances, Wwise filters modulation bypass and file conversion notifications.
  • WG-40614 Events referenced by Music Event Cues will be included in the SoundBanks only if the Structures inclusion option is selected for the appropriate project elements in the Add tab of the SoundBank Editor.
  • WG-40628 Rows in the parameter-modulator property list can be sorted according to their column values. There is an undo/redo event for sorting.
  • WG-40694 State transitions can now be edited while connected.
  • WG-40845 Automatically pinning objects to the Transport with Alt+Click is no longer possible. However, added new shortcuts to Toggle Pin (Ctrl+P) and Pin Selected Object (Ctrl+Alt+P).
  • WG-41643 The default communication monitoring queue memory pool size is now 256 KB (up from 64 KB), enabling bigger projects to have valid profiling information even when having a very large number of concurrently playing voices.

  • WG-36918 Moved Open Containing Folder contextual menu entries to a submenu.

  • WG-37797 Improved readability and reduced visual clutter of object icons.
  • WG-37799 Improved consistency and readability of placeholder text colors across views and skins.
  • WG-39230 Changed SoundBank Log items to have a string identifier instead of an integer identifier. This impacts the command line output during SoundBank generation and the WAAPI log functions and topics.
  • WG-39242 (WAAPI) Added Python samples using the waapi-client library and, to prevent clashes with the waapi-client library, renamed the include file to
  • WG-39254 Changed plug-in CPU statistics reporting to every audio frame instead of an average over ~200 ms.
  • WG-39289 Migrated Cube to Visual Studio 2015.

  • WG-40114 Updated layout of SoundSeed Grain UI.
  • WG-40395 Decreased the default envelope attack time for new SoundSeed Grain and SynthOne sources, to avoid low volume output at the beginning of their playback,
  • WG-40842 Changed the User Preferences' User Interface options to display a preview on the whole Wwise user interface, not just the User Preferences dialog.
  • WG-40889 (macOS) Changed location of saved configurations files to ~/Library/Application Support/Audiokinetic.
  • WG-40975 Renamed Destination Jump Position Preset property to Destination Sync To.
  • WG-41240 (WAAPI) Separated the State object type into two distinct types: CustomState type for users of States, and State type for the children of State Groups.
  • WG-41250 Stopped sending objects clicked in the Voice Monitor to the Transport, which would interrupt playback while profiling.
