Wwise SDK 2021.1.10
Release Notes 2021.1.10

The following sections list and describe the changes to Wwise between version 2021.1.9 and version 2021.1.10.
Platform-specific information can be found here:

For earlier versions, please refer to Previous Release Notes.

Behavior Changes

  • WG-60412 Multi-channel Audio Objects that are sent to the output device as System Audio Objects now have volumes similar to those of equivalent multi-channel sources being panned to a Main Mix or Passthrough Mix. This change reduces the volume of multi-channel System Audio Objects by several decibels depending on their channel count, for example -3db for a stereo source or -7db for a quadraphonic source. In practice, this means that any corrections to the mix that were made specifically for 3D Audio in this regard can be removed.

Performance Changes

  • WG-54292 (Spatial Audio) Reduced the number of redundant paths for room game objects.
