The following sections list and describe the changes to Wwise between version 2021.1.1 and version 2021.1.2.
Platform-specific information can be found here:
For earlier versions, please refer to Previous Release Notes.
New Features
-
WG-52085 Added
AK::SoundEngine::TryUnsetMedia API as a safer alternative to AK::SoundEngine::UnsetMedia.
-
WG-53816 New 2021.1 Spatial Audio features are now implemented in the Wwise Audio Lab, such as radial emitters, multi-positioning of spatial audio emitters, and the use of room tones instead of some ambiance trigger volumes.
API Changes
Behavior Changes
-
WG-54465 The Error Reporting tool now requires the user to fill in the field for additional information.
-
WG-54605 Various SDK functions, such as
AK::SoundEngine::SetRTPCValue and AK::SoundEngine::SetGameObjectAuxSendValues, now return AK_InvalidFloatValue and skip execution if values such as NaN or Inf are passed as parameters on Debug, Profile, and Release binary configurations of the Sound Engine. Previously, this was the case for Debug and Profile binary configurations, but not Release.
Performance Changes
-
WG-54125 Spatial Audio - Optimized path computation between portals and game objects so that the shortest possible path is computed.
-
WG-54472 Improved performance of Effects that use biquad filters, such as low-pass filters, Parametric EQ, and Reflect. The results are as follows:
- Throughput performance of mono processing improved by up to 2.5x.
- Throughput performance of stereo processing improved by up to 1.3x.
- Throughput performance of 7.1 and ambisonic processing improved by up to 2.2x.
-
WG-54505 Improved SoundEngine performance when
AkInitSettings::bDebugOutOfRangeCheckEnabled is enabled. Enabling this feature now increases CPU usage by a factor of 1.05-1.10x, instead of increasing CPU usage by a factor of 1.50x-3.00x, allowing it to be enabled in more scenarios.
