RealSpace 3D Audio

To create a convincing artificial audio environment for a user wearing headphones, sound processing must faithfully reproduce the acoustic spatial cues which would have been received at the ears from a real audio environment. These cues include those created by scattering off the listeners’ body (using a head-related transfer function or HRTF) and cues due to the environment (using customizable room models). RealSpace 3D achieves high resolution by including proprietary adjustments necessary to accommodate the complex interplay between the two cues.
Our efficient proprietary algorithms are already available for gaming engines. A native library, Unity plugin and Wwise integration are all available. Our plugins support complex scripting, and allow the game designer to interactively design the audio experience. Perception of 3D is enhanced when the HRTF of the user is customized. VisiSonics has developed technologies for HRTF personalization resolved by rapid measurement on anthropometry (physical measurements), and machine-learning based customization from a HRTF database.
