- WG-20963 Wii U: Can specify the number of audio buffers with AkPlatformInitSettings.uNumRefillsInVoice for more resilience against voice starvation.
- WG-21300 Support for Background mode (Home Button) on the Wii U. Use AK::SoundEngine::Wii::SetProcessMode to switch between the two modes. The IntegrationDemo demonstrates the home button support (look in Main.cpp).
API Changes
Environmental functions are replaced by auxiliary sends functions. The following functions are removed or replaced:
- AK::SoundEngine::SetGameObjectEnvironmentsValues()
- AK::SoundEngine::SetGameObjectDryLevelValue()
- AK::SoundEngine::SetEnvironmentVolume()
- AK::SoundEngine::SetEnvironmentVolumes()
- AK::SoundEngine::Query::GetEnvironmentVolumes()
- AK::SoundEngine::BypassEnvironment()
Refer to Environmental system is replaced by the Auxiliary Sends for more information.
- WG-20357 API change: SetEffect() were replaced by SetBusEffect and SetActorMixerEffect(), user must call the correct one.
- WG-20874 SoundFrame: GetGUID is now a method on ISFObject base interface.
Behavior and Performance Changes
- WG-20928 Wii U: Optimized the PeakLimiter 4.4x. It takes 0.2% of CPU (0.06ms) for a mono sound. Between 1.1 and 2.8x for all other platforms.
- WG-20929 Wii U: Delay effect optimized 2.3x. It takes 0.07% of CPU (0.02ms) for a mono sound.
