About Us

Founding Story

With the release of the Oculus and the promise of mass consumer-adoption of VR, High Fidelity set out to build the metaverse infrastructure that would support the next generation of user-generated virtual worlds and experiences. The company blazed trails for the digital worlds of tomorrow — including how these worlds will sound.

The Next Chapter

High Fidelity is more than our company name — it’s our credo. We have witnessed and experienced the transformational power of delivering high fidelity sound. We believe audio technologies should be designed for how the human brain is wired to process auditory information so people can feel as engaged with a digital experience as they would with a physical one. The portion of our lives that are spent wearing headphones should mirror the sonic richness we experience in the natural world.

Why Us?

If your team is too large, too slow, or more concerned with cutting costs than building cutting-edge technology, we might be exactly what you're looking for. We’re a small, seasoned team that trusts one another to be the expert in their domain and who are relentless about getting the job at hand done. Together, our mission is to connect people with extraordinary digital audio.
