Audio Output on Platforms

This section explains how Wwise will setup its audio pipeline for each platform.

Note: In all of the 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 48kHz. You can output at 24kHz by setting AkPlatformInitSettings::eAudioQuality to AkSoundQuality_Low when calling AK::SoundEngine::Init().

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.

Xbox 360™

On Xbox 360™, Wwise always outputs a PCM signal in the 5.1 configuration. From this signal, the console can provide the following signals:

  • Stereo (analog or LPCM)
  • Dolby Digital 5.1
  • Dolby Digital with WMA

Wwise always outputs at a sample rate of 48kHz.

Xbox One™

On Xbox One™, Wwise always outputs a PCM signal in stereo or 7.1. From this signal, the console can provide the following signals:

  • Stereo (Analog or LPCM)
  • 5.1 LPCM
  • 7.1 LPCM
  • Dolby Digital 5.1
  • DTS 5.1

Wwise always outputs at a sample rate of 48kHz.

PS3™

On PS3™, Wwise always outputs a PCM signal, in stereo or 5.1 depending on what is returned by cellAudioOutGetState. From this signal, the console can provide the following signals:

  • Stereo (Analog or LPCM)
  • 5.1 LPCM
  • 7.1 LPCM (not supported)
  • Dolby Digital 5.1
  • DTS 5.1
  • AAC
  • Dolby TrueHD (slim models only)
  • DTS-HD Master Audio (slim models only)

Wwise always outputs at a sample rate of 48kHz.

Make sure your PARAM.SFO file contains the encoders you wish to enable.

If you need more info check this in the PS3 SDK documentation: System Configuration > Audio configuration Utility Overview > 3 Audio Output Overview > Basic Procedure for the Application (Obtaining the Audio Format at Boot)

PS4™

On PS4™, Wwise always outputs a PCM signal in stereo or 7.1. From this signal, the console can provide the following signals:

  • Stereo (Analog or LPCM)
  • 5.1 LPCM
  • 7.1 LPCM
  • Dolby Digital 5.1
  • DTS 5.1

Wwise always outputs at a sample rate of 48 kHz.

Wii™

On Wii™, Wwise always outputs a PCM signal, in 4.0 (Front Left, Front Right, Rear Left, Rear Right). From this signal, the console can provide the following signals:

  • Stereo
  • Dolby Pro Logic II

Wwise always outputs at a sample rate of 32 kHz.

WiiU™

On WiiU™, Wwise always outputs a PCM signal, in Stereo or 5.1, depending on the initialization settings. From this signal, depending on the console settings, the console will provide

  • 48 kHz 2-channel LPCM
  • 48 kHz 6-channel LPCM

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 48kHz. You can override this sample rate by setting AkPlatformInitSettings::uSampleRate when calling AK::SoundEngine::Init().

Tip: To change the default device configuration in MacOS, 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 48kHz. You can override this sample rate by setting AkPlatformInitSettings::uSampleRate when calling AK::SoundEngine::Init().

Nintendo 3DS

On 3DS, Wwise always outputs a stereo signal at a sample rate of 32kHz.

PlayStation®Vita

On Vita, Wwise always outputs a stereo signal at a sample rate of 48kHz.

Android

On Android, Wwise always outputs a stereo signal.

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