Audio Output on Platforms
This section explains how Wwise will set 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 output at 24 kHz 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 48 kHz.
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
- Bitstream out (for Dolby and DTS Digital formats)
Wwise always outputs at a sample rate of 48 kHz.
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 48 kHz.
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
- Bitstream out (for Dolby and DTS Digital formats)
Wwise always outputs at a sample rate of 48 kHz.
Wii U
On Wii U, 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
Switch
On Switch, 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 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().
PlayStation Vita
On Vita, Wwise always outputs a stereo signal at a sample rate of 48 kHz.
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().
