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:

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().
