Wwise SDK 2021.1.8
Audio Output on Platforms

This section explains how Wwise sets up its audio pipeline for each platform.

Note: In all platforms, Wwise always outputs a PCM signal.

Windows

By default on Windows, Wwise takes the system default device's configuration. You can override the default configuration by setting the AkPlatformInitSettings::uChannelMask when calling AK::SoundEngine::Init().

By default, Wwise outputs at a sample rate of 48 kHz. You can override this sample rate by setting AkPlatformInitSettings::uSampleRate when calling AK::SoundEngine::Init().

When Allow 3D Audio is enabled on the System Audio Device, Wwise can also output 7.1.4 signals, a stereo passthrough mix as well as discrete Audio Objects. For more information on 3D Audio on Windows, see Enabling 3D Audio.

Tip: To change the default device configuration on Windows Vista and Windows 7:
  • Right-click the Speaker icon in the system tray
  • Select 'Playback Devices'
  • In the 'Sound' panel, select the device you want to use (use 'Set Default' to change the default.)
  • Click 'Configure' to change the configuration for the selected device
Tip: When using the Wwise Authoring tool, you can force a specific configuration by using the 'Audio' menu. Please refer to the user documentation for more information.

Mac

By default on Mac, Wwise takes the system default device's configuration. You can override the default configuration by setting the AkPlatformInitSettings::uChannelMask when calling AK::SoundEngine::Init().

By default, Wwise outputs at a sample rate of 48 kHz. You can override this sample rate by setting AkPlatformInitSettings::uSampleRate when calling AK::SoundEngine::Init().

Tip: To change the default device configuration in Mac OS, go to Applications/Utilities/Audio MIDI Setup.

iOS/tvOS

On iOS, Wwise always outputs a stereo signal.

By default, Wwise outputs at a sample rate of 48 kHz. You can override this sample rate by setting AkPlatformInitSettings::uSampleRate when calling AK::SoundEngine::Init().

Android

On Android, Wwise always outputs a stereo signal.

By default, Wwise outputs at a sample rate of 48 kHz. You can override this sample rate by setting AkPlatformInitSettings::uSampleRate when calling AK::SoundEngine::Init().

Linux

On Linux, Wwise outputs a stereo or 5.1 signal.

By default, Wwise outputs at a sample rate of 48 kHz. You can override this sample rate by setting AkPlatformInitSettings::uSampleRate when calling AK::SoundEngine::Init().
