For earlier versions, please refer to Previous Release Notes.
New Features
- WG-59168 The Audio file destination in the Audio File Importer is now persisted when closing and reopening the view.
- WG-69312 Added new parameters and controls to the Parametric EQ Effect, allowing it to act as a dynamic EQ. The Effect now supports metering of individual bands of audio when using a Low Shelf, High Shelf, or Peaking filter, which then drives a complementary offset to the gain of each of the filters being applied. The metering can be driven by either the in-line audio signal being processed by the EQ, or a separate Sidechain Mix.
- WG-75446 Added more visualization to the Parametric EQ's filter graph when profiling the sound engine. It now shows the frequency response of the filter driving the Parametric EQ based on the user-defined parameters, evaluated runtime RTPCs, and any dynamics processing.
- WG-75640 Added commands to the Command Buffer API to control stream caching, muting background music, sending custom data to plugins, and controlling the Suspended state of the sound engine.
- WG-76070 New experimental Recorder (ADM) plug-in allows recording a rich object-based mix to an ADM file.
- WG-77697 It's now possible to reorder the columns in the Media Pool Results pane.
- WG-77953 Right-clicking a Sound SFX object now provides options to search for similar sounds in the Media Pool.
- WG-77955 Added Show in Media Pool to the shortcut menu of Sound and Audio Source objects.
- WG-78560 You can now load a Profiler Session through the Profiler menu, from the Capture Log, and as a command in the Keyboard Shortcuts and Commands.
- WG-78690 Added shortcut menu options to the Media Pool Results pane that let you import detected regions of selected audio files.
- WG-78693 Added support for GameInput Advanced Haptics in the Motion plug-in.
- WG-78772 Added Copy Filename to Clipboard option in the shortcut menu of the Media Pool Results pane.
- WG-78807 Right-clicking a Media Pool database now provides options to add folders and rescan the database.
- WG-78893 Added new WAAPI functions to query the Media Pool.
- WG-79079 Added new Bands property to the Parametric EQ Effect, which lets you define the maximum number of bands the Effect will process. Even if bands above this number are disabled, lowering this value can slightly reduce the CPU and memory cost of the Effect.
- WG-79081 Added Channel Link Percentage property to Compressor and Expander Effects. This allows channel-unlinked processing to use a blend of a fully-downmixed signal and an unmixed signal when processing the gain reduction for the Effect.
- WG-79102 (Acoustics) When an emitter or listener moves around an obstacle, diffraction coefficients are now computed more accurately and with reduced reliance on updating the nodes within the path itself. This allows you to use a higher movement threshold, a higher load balancing spread, or larger clustering distances while minimizing loss of quality.
- WG-79331 Added a new API for plug-ins to query detailed information about the output device they are routed to.
- WG-79564 Added a Listen property to the Parametric EQ to solo parts of the audio being affected by a specific band of the EQ process. Also added a Dynamics Listen property to solo a specific band of the input signal being used to drive any dynamics measurements.
- WG-79841 Added the new boolean attribute "Temporary" to properties defined in a plug-in's XML description. When set, this prevents plug-in properties from being saved and persisted in the Wwise Project. This is useful for properties that are only meant to be used when Wwise is connected to the sound engine.
API Changes
- WG-69594 New API
AK::SoundEngine::ResetGlobalValues() can be used to reset States, RTPCs in the global scope, all changes made by Set Volume, Pitch, LPF, HPF Event actions, Effect Bypass flags, and Effects changed through AK::SoundEngine::SetEffect.
- WG-75457 Added the new
AK::SoundEngine::SetSidechainMixConfig API to provide custom channel configurations for Sidechain Mixes at runtime.
Behavior Changes
- WG-77002 Updated the Similar Sound Search SFXClap embedding model. Similarity scores are now more consistent and are more widely distributed between 0 and 1.
- WG-77583 You can now sort the list of files in the Media Pool Results pane by clicking column headers.
- WG-78137 Audio Source File paths in generated SoundBank content TXT files are now relative instead of absolute.
- WG-79323 The Motion Bus and Device are now in their own Work Units when importing Factory Motion.
- WG-79365 Moved Sidechain Mixes to their own category in the ShareSets tab of the Project Explorer instead of grouping them with Effects. Note that any Sidechain Mix ShareSets created in earlier Wwise 2025.1 Betas will be deleted, and you must recreate them. If you are migrating a project saved in an earlier Wwise 2025.1 Beta, project warnings will be generated for each Sidechain Mix ShareSet.
- WG-79488 SoundBank generation now reports an error for continuous containers used as a MIDI Target.
- WG-79659 Fixed: Distance Probe is not used for distance computation in Clustering.
- WG-79766 Fixed: Emitters that have different reflection properties or different diffraction properties are clustered together.
- WG-47170 Improved throughput performance of Metering functions when use of AVX2 instructions is active.
- WG-77254 Optimized network data usage for API Calls profiling.
- WG-78551 (Acoustics) Moved the calculation of indirect paths and reverb sends to a task. This code can now run in parallel and be load-balanced, if desired, which significantly reduces the cost of updating a game object position when using Acoustics.
- WG-79924 Greatly improved throughput performance when drawing most graphs in Wwise Authoring.
Miscellaneous Changes
- WG-78486 Added a spectrogram view to the Wwise Wave Viewer.
