SoundTeG Multichannel Output

SoundTeG Multichannel Output is an output plug-in for Wwise that routes audio to a multichannel audio device. It currently supports Windows and macOS only and provides the same plug-in functionality on both platforms.

Setup guide

Currently supported Wwise version: 2025.1.11.9262. The setup workflow is the same on Windows and macOS. These screenshots were captured on Windows; the ASIO and WASAPI notes below apply to Windows. Click any screenshot to open a larger view.

1. Install the plug-in

In the Wwise Launcher, install SoundTeG Multichannel Output for the Wwise version used by your project.

Install SoundTeG Multichannel Output for the Wwise version used by your project.

2. Create a project

Create a new Wwise project for this walkthrough, or use a project in which you want to configure multichannel output.

Create a Wwise project for the output setup.

3. Create the Audio Device

Under Devices → Default Work Unit, choose New Child → SoundTeG Multichannel Output.

Create a SoundTeG Multichannel Output Audio Device.

Open the Audio Device to view the Auto-detect setting. Its description is also available in the Contextual Help panel.

Open the plug-in interface and read the Auto-detect description in Contextual Help.

4. Assign the device to Main Audio Bus

Select Main Audio Bus and set its Audio Device to the SoundTeG Multichannel Output device created in the previous step.

Before generating SoundBanks for other platforms

SoundTeG Multichannel Output supports Windows and macOS only. When generating SoundBanks for an unsupported target platform, such as Android, make sure that Main Audio Bus is not assigned to the SoundTeG Multichannel Output Audio Device. Select an Audio Device supported by the target platform before generating its SoundBanks.

Assign the SoundTeG Multichannel Output Audio Device to Main Audio Bus.

5. Create and configure a test bus

Create a child Audio Bus under Main Audio Bus.

Create a child Audio Bus for the playback test.

Choose the Bus Configuration for your signal path. The screenshot uses an ambisonic bus. For an ambisonic-to-loudspeaker decoding setup, follow the SoundTeG Ambisonic Decoder guide.

Choose the bus configuration for your test. The screenshot uses an ambisonic bus.

6. Create and position a test sound

Create a Sine source under a Contents Work Unit.

Create a Sine source for a playback test.

For listener-relative positioning in a game, open Positioning, enable Listener Relative Routing, and set 3D Spatialization to Position + Orientation.

Enable Listener Relative Routing and set 3D Spatialization to Position + Orientation.

7. Route the test sound

On the sound’s Routing tab, set Output Bus to the test bus.

Route the test sound to the bus created earlier.

8. Check the hardware output

Play the test sound. Check the selected physical audio device and its available output channels, then inspect the Main Audio Bus meters. With Auto-detect enabled, the output configuration is chosen from the detected device’s output channel count.

Inspect the physical audio device and its available output channels. ASIO is also supported.

With Auto-detect unchecked, the output uses an Anonymous configuration. In the example below, the meter reports eight Anonymous channels.

Auto-detect unchecked: the Meter view shows an Anonymous output configuration.

Plug-in properties

Auto-detect

Auto-detect chooses the output configuration based on the detected audio device’s output channel count.

Setting	Output configuration
Enabled	Uses a standard speaker layout for 1–8 channels and Anonymous for 9 or more channels.
Disabled	Always uses Anonymous, with no assigned speaker roles.

Standard layouts with Auto-detect enabled

Device output channels	Layout
1	Mono
2	Stereo
3	2.1
4	Quad
5	5.0
6	5.1
7	7.0
8	7.1
9 or more	Anonymous

When enabled, Auto-detect configures the output in a similar way to Wwise’s built-in System output.

Authoring Audio Preferences and ASIO

In Wwise Authoring, Authoring Audio Preferences can override the device assigned to Main Audio Bus. Select the SoundTeG Multichannel Output entry paired with the hardware you want to use. The example selects ASIO4ALL v2.

Select the plug-in and ASIO hardware in Authoring Audio Preferences.

Windows: SoundTeG Multichannel Output falls back to WASAPI when no ASIO device is installed. An ASIO device may not appear in the Windows taskbar’s playback-device list; select it through Wwise’s Authoring Audio Preferences. Always verify both the physical audio device and the SoundTeG Multichannel Output Audio Device plug-in selected in Wwise. Authoring Audio Preferences apply while authoring and not connected to a game.

Troubleshooting

Playback uses the wrong device or is silent

Confirm that Main Audio Bus is assigned to your SoundTeG Multichannel Output Audio Device.
Check Authoring Audio Preferences for a hardware override.
Confirm that the test sound routes through the intended bus.
Check the physical device’s output channels and the Auto-detect setting, then verify the speaker outputs with a test signal.

An ASIO device is absent from the Windows playback list

Use Authoring Audio Preferences in Wwise to select the plug-in and ASIO hardware.

For further help, contact Support with your Wwise version, plug-in version, operating system, audio device, speaker layout, and a description of the result.
