By 2017, no product has been able to accomplish that1.

We want to play music on our phones and headphones, as if it was live, with the artist in front of me, with such realism that we’re unable to distinguish from reality, better than a stereo system.

In-ear headphonesPlanar headphones

High-end headphonesNoise cancelling

Some great technologies, but none able to reach that goal yet.

1 The Smyth-Research Realiser A8 is to our ears the closest to that goal, however is an expensive product, not designed for mainstrem or mobile.

To get there, we would need to overcome technical complexities that the VR industry estimates could take up to 5 years.

“The computational demand of implementations are so high that only certain sort of constrained virtual spaces will be practical for five years.”M. Abrash - Chief Scientist, OculusOculus Connect on 3D Audio, Oct. 16

To get the quality and realism using the computing capabilities of today, we had to approach the problem from a different perspective.

SynthesizingVirtualRoom 3DAcoustics

Measuring & Reconstructing Real World 3D Acoustics

Reduced computing requirementsVastly increased quality(real data instead of modeling and lengthy fine tuning)

Very precise measurement techniques and processing

What are the benefits of this approach

At the cost of

from to

The good news is: It works, like magic.Choose your song, hear as if the band is alive, just in front of you

Bluetooth sensorCapable of tracking the head position, so no matter where you look, the music stays fixed in 3D space

iOS Stage AppFast enough to run on a phone, accurate enough to reconstruct a stage, with absolute detail

HeadphonesCalibrated to eliminate unwanted frequency distortions

Functional prototype

The Stage Selection allows to listen on different concert stages and studios, let’s say...Beyonce on the MET Opera, sure!

Each stage accurately retains the original acoustic signature completely with head tracking for total immersion.

Back orchestraAlmost 20 feet above the orchestra

floor, this seat has an airy soundstage; music reverberates along the entire house creating a

magnificent soundstage

Spatialization is great, but realism means to also hear the stage and its acoustic signature, as a key of the live music experience

Stage selection requires commercial agreements for commercial use.

We strongly believe this technology has the potential to become a big feature for mobile phones.

VR for music is capable of:

All 3 are Ingredients for an important feature

—generate a powerful wow factor, similar to VR—create a huge desire to own it (and show off)—radically improve the listening experience

What’snext?

Example: Apple important iPhone features history:

Key PointsWe have developed a new algorithm, iOS app and sensor capable of recreating live music using VR techniques specially designed for music

The algorithm, implemented as an iOS app runs on modern devices, with reduced CPU-energy consumption.

We believe this technology could create a great impact as it’s easy to produce, it’s desirable and opens the door for additional great VR music content

3Now, why are you reading this? :)

This tech was not developed by a large corporation but by 3 people on a startup from Santiago, Chile (that’s 6.000 miles from Silicon Valley). We want this tech to succeed, and while we’re already starting conversations with industry players, we want you to try it, give us your opinion and somehow be part of what could become a feature that people will be talking in the future.

We are a team from Chile that loves music, engineering and cutting edge technology.
