Panning on a 3D configuration
Wwise Help
Note For context, reference the first example. When panning on a 3D channel configuration, meaning a configuration (such as 7.1.4 or ambisonics) that can represent sound coming from above and/or below, the virtual sources are disposed in the shape of spherical caps. The following figures show stereo and 4.0 sources with various Spread and Focus.Recall that 3D positioning only takes up to 7 input ...
Environments
Wwise Help
Many of the same considerations discussed in Cinematic VR apply to Auxiliary Busses used for environmental Effects. The RoomVerb and AK Convolution Reverb Effects support ambisonics natively, however Matrix Reverb does not. You can use them on a stereo, 4.0, or greater bus, whether you want to use the front-back delays or not, and route them to ambisonic busses. Their output will be encoded to ambisonics ...
Soundseed Grain tips
Wwise Help
Although it is also very relevant to output, say, first order ambisonics, and mix it into a third order ambisonics bus.Set the Positioning mode to 3D Spatialization.Use random modulation with Azimuth and/or Elevation.You may use Spread to your liking (to fill the space for example). Make sure Spread is greater than 0 if your material is multichannel, otherwise each grain is treated as a point source ...

My setup:I have a 3D Wwise event (game-defined position) It's playing from an AkAmbient actor in UE4It's routed in Wwise to an ambisonics 3-3 buswhich goes to a binaural bus that uses sce_Audio3d (this bus is also set to Ambi 3-3)and then to the master bus as stereo (Wwise audio output set to Stereo Speakers)What's wrong:When the listener turns away from the emitter, ...

Oriented Reverb
Wwise Audio Lab
Description: Late reverb playing from a 3D bus keeps its orientation with regard to the Room, which makes for a convincing sense of presence. This example showcases the AK Convolution Reverb plug-in using a first order ambisonics IR that purposely steers the energy in one direction. Note: The IR has been exaggerated to make the oriented reverberation effect more obvious.
Ambience Fantasy Collection Guide
Strata Help
Ambience Fantasy offers a range of environments that articulate the fantasy world. The various Area, Interior, and Drone subprojects represent common aspects of magical fantasy lore. The drone subprojects are especially useful for establishing an air of fantasy in any natural or urban ambience.The subprojects are mixed using higher order ambisonics with assets recorded in ORTF-3D. They are set up ...
Ambience Medieval Collection Guide

Ambience Medieval offers a wide variety of sounds that articulate the Medieval world. The Area and Interior subprojects represent aspects of medieval life, the city, day and night, tavern, church, harbor, back alley and market place. These subprojects are mixed using High Order Ambisonics with assets recorded in ORTF-3D, and are set up to render in a variety of common multichannel ...

For example, ambisonics will be decoded or encoded if needed. Note: The function will fail if the input or output configuration is object-based, as the speaker volume matrix would be undefined. All panning or spatialization types are honored. 3D Spatialization is performed relative to the default listener position (0,0,0) and orientation, where the front vector is (0,0,1) and the top vector is (0 ...

Authoring Audio Objects
Wwise Help
Mix is an intermediate representation of sounds and their positions rendered in a channel-based format (for example, 5.1, 7.1, 7.1.4, or ambisonics). This produces a mix suitable for virtualization (that is, virtual positioning according to ideal speaker positions) and binauralization.In the Audio tab of the Project Explorer, right-click the Master Audio Bus and select New Child > Audio Bus.
