Oculus Audio SDK

Oculus Audio SDK is a development kit that was designed to help VR developers integrate audio content within their projects by providing them with various relevant features.

Among the components mentioned above, users can find the OculusHQ sound rendering path and also several other plugins for game engines, audio middleware, as well as VSTs and AAX ones.

This Software Development Kit supports both spatialization and environmental modeling, thus offering users multiple possibilities to enhance the quality of their projects.

Oculus Audio SDK makes use of HRTFs (Head-Related Transfer Functions) and provides audio spatialization for developers through plugins and the C/C++ SDK alike. However, users must make sure that all the sounds processed by the spatializers are monophonic.

The HRTFs offer effective directional cues that might be perceived as simplistic or dry without emulated room effects. In this case, environmental modeling can come in handy, especially if developers want to give the sound a richer feeling.

The SDK helps VR developers create a virtual room around the users' heads, based on a “shoebox” model, providing them with a richer experience, sound-wise. The simulated room consists of four parallel walls, a ceiling and a floor, set at varying distances, so that each can produce a distinct reflection.
