Release Notes 2019.2

The following sections list and describe the changes to Wwise between version 2019.1.7 and version 2019.2. For earlier versions, please refer to Previous Release Notes.

Platform SDK Changes

  • (PS4, Windows, UWP) These platforms now support SDK builds for Visual Studio 2019.
  • Authoring requires Windows 7 SP1 and up. Changed the Wwise Authoring tool, including all plug-ins, to be compiled using Visual Studio 2019, with Windows SDK target version 10.0.17763.0.

New Features

  • WG-26680 Added the Resource Monitor, which lets you monitor resources used by the sound engine from within a game running Wwise. No Authoring needed.
  • WG-32589 (WAAPI) New WAAPI command to capture an image from the Wwise user interface.
  • WG-39654 Users can now create, edit and reload custom command files, using their default JSON editor directly from Wwise, in the User Preferences.
  • WG-40348 Custom properties and Command Add-ons are now logged once loaded.
  • WG-40381 (WAAPI) Added the ak.soundengine.setState function.
  • WG-41088 New presets for Spatial Audio Auxilirary busses in Wwise Authoring: Room Reverb and Reflect.
  • WG-41090 Stochastic ray-tracing is now used to compute Reflections and Diffraction, in Spatial Audio.
  • WG-41111 New Spatial Audio and Wwise Reflect factory presets.
  • WG-41112 Presets now support multiple work units.
  • WG-41223 A new sub menu is now available to create a new child or a new parent from a preset.
  • WG-41481 Custom commands can now use common directory variables in program, args and cwd fields, in order to avoid machine-specific absolute paths.
  • WG-41530 WwiseConsole is the new WwiseCLI. WwiseConsole supports new syntax, built-in help display and strict validation of arguments. WwiseCLI is now deprecated but remains available.
  • WG-41727 Fixed: (WAAPI) Platform names can now be used as the platform argument in WAAPI instead of a GUID.
  • WG-41953 Custom commands can now use the new redirectOutputs field, in order to redirect the standard output streams of the program (stdout + stderr) to Wwise on termination.
  • WG-42470 Added support for 4th and 5th order ambisonics.
  • WG-42755 (WAAPI) WAAPI Subscription Publish messages are now displayed in the WAAPI tab of the Wwise Log.
  • WG-42812 A new Profiler view, the Voice Explorer, has been added. It enables you to list playing voices, sorted by playing events and game objects.
  • WG-42814 A new Filter bar has been added to most Profiler views, enabling you to search specifically for game objects, sounds, buses, events and more.
  • WG-42829 The new Voice Explorer profiling view is now available.
  • WG-42963 The Lumin Integration Demo is now available when performing a normal installation, using the Audiokinetic Launcher.

  • WG-43465 It is now possible to create/edit/remove command Add-ons directly from the Keyboard Shortcuts and Commands dialog.
  • WG-43498 Parameteric EQ effect properties, Band Gain and Output Gain, now support multiple RTPCs and/or States.
  • WG-43544 Users can now create and edit custom command files, using their default JSON editor, by choosing one of the three predefined directories directly from Wwise, in the User Preferences.
  • WG-43580 The Game Simulator now supports Magic Leap.
  • WG-43809 You can now search for and execute Wwise Commands directly from the main Search Bar by inputting ">" (without quotes).
  • WG-43889 (WAAPI) New WAAPI commands to support granular SoundBanks:
    • Added more information to the info file
    • Each Event lists their associated media.
    • Each SoundBank lists their associated AuxBuses, Game Parameters (RTPC), Switches, States and Triggers.
    • Each event lists a tree of Switch value to Media ID, allowing to only load media when the Switch value is referenced in a given level.
    • Added a new WAAPI command: ak.wwise.core.soundbank.generate. By default, it generates SoundBanks using an in-memory SoundBank generation model. You can also direct it to write the SoundBanks to disk in the default SoundBanks Generated folder. In the command, you can specify a list of SoundBanks and customize their inclusions. You can use the WAAPI callback: ak.wwise.core.soundbank.generated to get the SoundBank data encoded as base64 and the JSON info file embedded within the WAAPI callback.
    • Added the WAAPI callback: ak.wwise.core.soundbank.generationdone, when the SoundBank generation is done.
    • Added the –skip-languages WwiseConsole command line switch to skip generation of localized SoundBanks.
    • Added the –use-stable-guid WwiseConsoloe command line switch for projects that don't save SoundBanks in their Wwise project and want a stable GUID in their info file.
  • WG-44057 Added versioning to Command Add-on definition files.
  • WG-44358 The Game Sync Monitor has been redesigned to remove dependency on watches and benefit from Voice Inspector data.
  • WG-44511 It is now possible to create Work Units and Folders in the Master-Mixer Hierarchy.
  • WG-44633 Added AK::IAkIOHookDeferredBatch, a new interface for handling deferred I/O operations. It enables performance improvements to I/O threading CPU utilization and allows for greater flexibility in ordering and dispatching concurrent I/O requests, when many concurrent I/O requests are submitted.
  • WG-44974 (WAAPI) Added new settings to control the maximum number of concurrent clients that can be connected to Wwise through WAAPI. These settings can be modified in the User Preferences or through the command line.
  • WG-45522 The search field is now displayed by default in the Keyboard Shortcut Dialog.
  • WG-45682 (WAAPI) Added ak.wwise.core.profiler.getRTPCs to retrieve active RTPCs for profiling cursor time.
  • WG-45746 The Game Object 3D view is now available on macOS, without the 3D area.
  • WG-45797 Added a splitter in the Reflect Effect Editor between the curves graph and the list.
  • WG-46067 Double clicking a game object in the list view automatically locates the object in the Game Object 3D View.

API Changes

  • WG-35130 Wwise now uses civetweb v1.11.
  • WG-39381 Memory Manager interface: see New Memory Manager.
  • WG-39563 Added a new error code: AK_PlayingIDNotFound, for calls to SetRTPCValueByPlayingID.
  • WG-40342 A new AkGlobalCallbackLocation has been added: AkGlobalCallbackLocation_Init, which lets users register for a callback right after the sound engine initialization.
  • WG-40738 Several additional Wwise UI operations are now bound to Wwise commands.
  • WG-41513 The GetRegistryPath method has been removed from AK::Wwise::ISourceControlUtilities.
  • WG-43542 (WAAPI) The WAAPI C++ client, in AkAutobahn, now supports timeout on Connect. This allows for timing out during the WAMP handshake, in order to avoid a potential infinite lock, if Wwise stops responding at the wrong time (if it is closed, for example). The API change is backward compatible and should not require code changes, unless you want to specify the timeout value.
  • WG-43648 AK/Wwise plug-ins API stability enhancements, by using the Wide version of parameters when applicable
  • WG-44516 Seek is now supported in DynamicSequence.  The seek operation can only be performed on the first item.
  • WG-44635 Added a new setting to sound engine initialization, AkInitSettings::uBankReadBufferSize, to allow for the customization of read granularity, when loading SoundBanks from a file.
  • WG-44661 Added AK::IAkStdStream::WaitForPendingOperation() to allow the blocking of IO Streams that issue an asynchronous task.
  • WG-44710 Added IAkGlobalPluginContext::ApplyGain and IAkGlobalPluginContext::ApplyGainAndInterleave so that sink plug-ins can use the sound engine's existing capabilities to perform final rearrangement of audio data for certain hardware, for example, as part of the device sink plug-in processing.
  • WG-44835 (Stadia) Removed SDK/include/AK/Tools/GGP/AkPlatformFuncs.h, in favor of Linux/AkPlatformFuncs.h, which should be used moving forward.
  • WG-45352 Soft deprecatation of AkGetSinkPluginDevices to be replaced by AK::SoundEngine::GetDeviceList implementation by plug-in registration of static functions.
  • WG-45977 Updated SetReflectionsOrder function in SpatialAudio to update reflection and diffraction paths (or not), based on a boolean argument.
  • WG-46117 Added new setting to sound engine initialization on Windows, AkPlatformInitSettings::bEnableAvxSupport, to disable any utilization of AVX and AVX2 in the sound engine and plug-ins.

Behavior Changes

  • WG-40568 Seeks are now performed without a seek table in Vorbis by default. If a seek table is not provided, Wwise decodes from the start of the file to the seek point. For anything but small files, it is highly recommend to still include a seek table. A warning is displayed when performing a seek operation within larger Vorbis files without a seek table.
  • WG-41425 The plug-in development tools now require the -x flag when building for Wwise Authoring, since plug-ins can now target either vc_140, vc_150 (vc_141) or vc_160 (vc_142). They were previously restricted to vc_140. The development tools now detect Visual Studio installations with compatibility build tools as potential candidates to build plug-ins.
  • WG-42182 (WAAPI) Calling WAAPI functions with invalid arguments or options now provides more details in the error message, including inline documentation, and better formatting of error messages.
  • WG-42469 Changed several things regarding media asset ID assignments: Added undo-redo operations to ensure assignments remain consistent. Moved MediaIDs to their own space; value space is no longer shared with other types of assets. Changed the algorithm used for assigning MediaID values. Changed Work Unit tags for MediaID values from <ConvertedFileIDList> to <MediaIDList>.
  • WG-42853 Fixed: Previous default shortcut for View Settings did not work on "undocked" views. The default shortcut: Ctrl+Alt+V, has been changed for: Ctrl+Alt+H.
  • WG-43056 Fixed: Containers with trigger-rate transitions could play out-of-sync when placed inside containers with sample-accurate transitions.
  • WG-43643 The ID of a State Group's None State is no longer 0.  The None State's ID is now specified in Wwise_IDs.h.
  • WG-43897 Profiler Settings: Increased maximum memory usage limit from 4000 MB to 32000 MB.
  • WG-44440 HDR is now disabled on a voice's sends if its dry signal does not pass through an HDR bus.
  • WG-44680 (WAAPI) "Object ID is unknown" error message now have more information about the ID or the path you where trying to find.
  • WG-44707 Added dB level to the image sources list, in the Wwise Reflect UI.
  • WG-47232 Native ambisonics decoding to stereo is now completely symmetrical regardless of whether sounds come from the front or the back. Previously, sounds coming exclusively from the back were silenced.

Performance Changes

  • WG-40847 Improvements to the conversion from linear to dB volumes at runtime.
  • WG-41951 (WAAPI) WAAPI now uses undo groups, which results in better performance by reducing the number of updates to the user interface.
  • WG-42619 Vorbis codec optimization, providing between 5% and 20% of additional gain.
  • WG-43026 Optimized SoundBank generation, by removing costly dynamic_cast.
  • WG-43631 Performance improvements to Wwise Authoring, when selecting objects in the Project Explorer.
  • WG-44449 A new cache system has been implemented for working buffers, greatly reducing the number of buffer allocations required at runtime.
  • WG-44634 Loading SoundBanks from a file now issues asynchronous reads when possible, slightly reducing the the total latency of SoundBank loads.
  • WG-45592 Improved 3D Meter performance.
  • WG-46588 Improved performance while loading projects in the Loading Layouts phase.

Miscellaneous Changes

  • WG-32483 (XBox One) Removed unnecessary dependency on dxguid.lib on Windows and Xbox One.
  • WG-32511 SoundBank generation and audio file conversion can now write files with paths that exceed MAX_PATH (260 characters) on Windows 10, given that long paths are enabled on the machine. Click here for more details.
