Personalized 3D Audio for Virtual Reality


 

 

Maximum Presence


Maximum Presence


Presence has been described as "the magic of Virtual Reality" -- the combination of a wide viewing angle, low latency graphics and six-degree tracking of head position which essentially hacks your brain into believing that what you are seeing and experiencing is real.

I believe that 3D sound is an essential part of creating a sense of presence...without 3D sound it’s very easy to break the immersion.
— Shuhei Yoshida, President of Worldwide Studios, Sony Computer Entertainment

To obtain the deepest sense of presence and immersion, the audio experience will need to be as realistic as the visual one.  

Unfortunately, all current 3D audio solutions are based on generic hearing profiles -- so any sense of realism is limited by how similar your ears are to those generic ears.

Why listen through generic ears when you can listen through your own?

...if audio is really good...you won’t even know why but the experience will be far, far more real.
— Michael Abrash, Chief Scientist, OculusVR

Audio engineers have long known that the best way to create realistic audio is to replicate the way that we hear things naturally.  

Each person's hearing is individualized, and this is primarily a result of the direction of the sound interacting with the shape and size of the head and ear, as well as the sonic nuances created by the folds of their outer ear. 

Head Related Transfer Functions (HRTFs) are the technical specifications for recreating hearing in a 3D environment based upon these things. Traditionally, capturing HRTFs has been a time-consuming and unwieldy process.  For this reason, every commercial 3D audio solution to date has taken a set of HRTF data, and tried to create an “average” that is intended to work for the general population. 

We have developed a patent-pending process that simplifies the capture of personalized HRTFs, allowing you to listen to sounds “through your own ears”, just as nature intended.

We call these personalized datasets Earmarks.

Capture your Earmark


Capture your Earmark


Our Earmark Capture Kit contains everything you need to capture your own Earmark:

  • Lab-grade omnidirectional ear microphones (+/- 1.5dB, 20-20kHz)

  • High quality USB 2.0 audio DAC with phantom power (16 bit, 48khz, THD+N = 0.01%, SNR 89dB)

  • 3" powered reference speaker

  • Earmark Capture App (Windows, Mac, Linux) for use with VR headsets

The capture process is simple:  Just connect the ear microphones and reference speaker to the USB audio DAC, don your VR headset, and follow the instructions given to you by the application to capture your personalized Earmarks and upload them to our servers.

Once on our servers, your Earmarks are optimized using advanced audio signal processing algorithms and are then made available to application developers in any format or resolution necessary for use in VR applications.  And since we're continually improving our algorithms, your Earmarks will only sound better and better over time!
