VR Audio Engine

3D Sound Labs Hybrid 3D Audio Engine

Because we believe HOA paradigm is key to the future of 3D audio, we have developed a novel way to render HOA based content over headphones that provides less sound coloration and use much less CPU than traditional virtual speaker based implementations.
3D Sound Labs VR Audio Engine combines both object and HOA 3D audio engines, providing a high performance multiplatform 3D audio engine capable of rendering complex audio scenes in real time.

VR Audio Kit Features

HRTF Based Binaural Rendering

The VRAudioKit engine uses Head Related Transfer Functions (HRTF) to acurately transform sound sources and make them sound as tough they originate from a specific desired direction.
The listener can therefore acurately localize sound sources both in azimut and elevation.

Environmental Modeling

An HRTF provides strong directional cues, but without room effects, the sound is often dry and lifeless. Some environmental cues (e.g. early reflections and late reverberation) are also important in providing strong cues about the distance to a sound source.
The VRAudioKit engine supports early reflections and late reverberation by providing a simple room model consisting of a virtual room with four parallel walls, a floor and a ceiling at varying distances with adjustable reflection coefficients.


The VRAudioKit engine processes sounds in the spherical harmonics domain called High Order Ambisonic (HOA) which makes the engine fully scalable in terms of sound source number and platforms.


3D Audio Formats compatibility

The VRAudioKit engine supports monophonic point sources as well as surround multichannel or ambisonic (HOA) audio “beds”.
It supports all ambisonic audio formats (FUMA, ACN-SN3D, SCN-N3D, SID-SN3D, SID-N3D, …) which makes it fully compatible with new 3D audio formats such as Dolby Atmos, MPEG-H 3D Audio or Youtube 360.
