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: 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 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().
