Ambience Warfare Collection Guide
Strata Help
Ambience Warfare provides multichannel ambience bed tracks for battles of various eras: modern, medieval, historical, and sci-fi. The tracks feature weapons, other ordnances, and vehicles of each era.The ambient bed subprojects are mixed using higher order ambisonics with assets recorded in 1st order AmbiX. They are set up to render in a variety of common multichannel formats to suit your requirements ...
They have items with mono or stereo source files, which are not mixed using ambisonics.All Basic Layer tracks use yellow custom colors, alternating between light and dark shades.Details Layer 2Depending on the ambience, there might be a Details Layer with dynamic elements of battles, like explosions or swords. The item source files for these are AmbiX recordings. Depending on the type of ambience ...
Submersion Collection Guide
Strata Help
The Submersion collection is arranged in subprojects that cover an expensive range of highly flexible sounds in a broad range of environments. The objects making those sounds are easily customized using multiple control tracks. The Underwater Ambience subproject is mixed using higher-order ambisonics. This subproject is set up to render in a variety of common multichannel formats, ranging from binaural ...
About the Wwise Sample Project
Sample Project
Dialogue—A demonstration of how to create dialogue that changes dynamically according to actions in game. Ambisonics —A demonstration of the surround sound of ambisonics through the binauralization of an Audio Bus using the Auro Headphone Effect. Music—These examples demonstrate different techniques for arranging and implementing interactive game music using pre-rendered audio ...
3D positioning illustrated
Wwise Help
Spread and relative emitter-listener rotation is identical, regardless of the configuration types.You can pan sources with standard configuration into ambisonic busses ("encode to ambisonics"), and vice-versa ("decode from ambisonics").ExamplesThe examples in the following pages illustrate various facets of the algorithm presented above: Effect of Spread Effect of orientation ...
Focus
Wwise Help
Focus, input channels always contribute to at least 2 output channels unless they are perfectly aligned.This issue does not apply with ambisonics panning, which, by design, already leaks across output channels, albeit uniformly. Therefore, Focus is ignored when the channel configuration of the source is ambisonics. Effective Panning of an Emitter Located 45 Degrees from the Listener's ...
Effect of Height Spread
Wwise Help
This is because ambisonics is a speaker-agnostic format, and the headphone or speaker setup on which it will be later decoded is unknown at the time of panning. If that setup turned out to be a planar speaker configuration, it would not benefit from Height Spread. However, ambisonics is a representation that is intrinsically smooth, and this smoothness should suffice to mitigate the artifacts that ...
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 ...

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.
For ambiences, which have bed tracks that are not usually highly positional by design, listening experience and quality testing have shown 3rd-order ambisonics to be optimal in terms of CPU usage, channel count, memory footprint, and common speaker monitoring systems. This applies to most current generations of video game hardware.The following image shows the routing ...
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.

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 ...
