Personalization - VisiSonics

Fully optimized sound for every user

VisiSonics personalizes sound with our unique, customized HRTF modeling and audiogram measurements.

We combine our spatial audio rendering engine and personalization technology to create a fully optimized sound customized to each individual’s ear shape. VisiSonics has developed a method to extract HRTFs from visual information, aided by machine learning and our proprietary database of traditionally acquired HRTFs, the largest database of HRTF available. With VisiSonics technology, it is possible to generate an accurate HRTF from a few pictures taken on a smart phone. Our algorithms incorporate data from both ears and the distance between the ears – all of which vary by each individual.

In addition, VisiSonics is taking personalization to the next level with audiogram technology that enables customization based upon individual listening capabilities.

HRTF Overview

In spatial audio models, the Head Related Transfer Function (HRTF) is an equation that defines the way sound scatters off a person’s head, shoulders and ears, and ultimately enters the ear canals. Together with room modelling, it is one of the defining elements in an effective virtual spatial audio environment.

Everyone has a differently shaped head, body proportions and ear shape. Small differences in any of these measurements or relationships can have a dramatic effect on sound accuracy and realism.

Mobile App Makes Personalization Simple

Rather than a user needing to be in a special audio lab to map their HRTF, VisiSonics has developed a method to extract HRTFs from visual information, aided by machine learning and our large databases of traditionally acquired HRTFs. We have exclusive access to the important data that is able to accurately resolve HRTFs from visual information.

Integrating Personalization

VisiSonics currently makes personalized HRTFs available to integrate with all of our RealSpace applications. This includes our embedded, DSP solutions, software solutions and our plugins for gaming developers using Wwise, Unity and Unreal.
