Live Spatial Audio API Alpha Available

by Philip Rosedale Cofounder + CEO

As a developer, you can now add High Fidelity's Spatial Audio to your project with our API and a few lines of code by starting here. Spatial audio means that people can talk naturally at the same time, because you hear different voices coming from different places.  High Fidelity offers the highest audio quality and minimal delay for longer, warmer conversations and happier people using your app. Music as well as stereo sources are also supported.  A live demo letting you move around and experience High Fidelity is here.  

High Fidelity’s Spatial Audio API is free during alpha, with per-minute pricing once we start billing.  Next up, we will be adding Unity support.  A roadmap of our development plan is available here.

"High Fidelity is far better than anything else on the market. Their audio technology powers the amazing 3D spaces in SpatialWeb.net, allowing us to create a true feeling of remote togetherness."

— Eric Pulier, CEO, SpatialWeb 

"What we have seen and been able to test so far is just awesome! This is exactly the type of solution our team has been looking for."

— Ara Kevonian, CEO, Soundstage

What Makes High Fidelity’s Spatial Audio API Different

To start, we have made it fast and simple to implement. Our sample apps and guides walk you through each step. For example, you can Build a Simple Web Application that allows two or more people to talk to each other in a virtual 3D environment. Or you can try something more advanced, like Build a Web App with the Spatial Audio API, Express, and EJS.  

High Fidelity mixes the audio streams on the server-side and delivers a single spatialized stereo audio stream back to your application’s client using the well-tested WebRTC protocol. This also means there is minimal CPU load for your customers and enables it to work on most devices, including mobile.  Your app only manages one server connection per audio input source, no matter how many people are using your application together at the same time.   

Lastly, the sound experience feels so natural and immersive because the delay is imperceptible. (Learn more about the Six Second Rule in our blog post, How To Treat Zoom Fatigue.) If you know about our company history, then you know that our audio tech was initially built for our VR platform. Making audio sound this good isn’t easy, and we have been obsessive about audio quality from day one. Some companies spend their resources pushing the envelope of visual quality, rendering more beautiful polygons per second or improving texture quality. We spend our resources pushing the envelope of audio quality lowering latency, nailing spatialization, and more. It’s deeply embedded in who we are as a company and our brand. 

Our Roadmap

We'll keep you posted as to what is currently underway, what's planned beyond it, and what stuff we aren't sure about yet.  We have already had tons of interest in iOS and Unity, so we’re kicking off the work to build those SDKs now. Check out our current Roadmap here, and give us some feedback — your requests drive our roadmap.

Questions or Comments

We have an initial FAQ that we will continue to build out. If you think there are things we should add, ask us in the comments below or email us at support@highfidelity.com. Most importantly, we hope you will accept our invitation to join our early alpha program. We can’t wait to see what you build and are eager for your feedback.
