What Is Spatial Audio And Why Is It Better?

For starters, conventional VOIP audio is like using walkie-talkies. Only one person can talk at a time, and it sounds like everything is coming from a single source because it's mono.

Spatial audio recreates the way we hear sound in real life. Spatial audio delivers sounds so each source comes from a defined location in space. This makes each sound clearer and easier for the listener to understand.

Speakers are more intelligible
Participants feel more present and engaged
Powers more natural conversations
Many conversations can take place together
No ducking or clipping speakers

Hear the difference.
Go ahead. Everybody talk at once.

Listen with headphones for the best experience

What if the audio in your app sounded like this?

Put on a pair of wired headphones for the best experience and imagine how great your application can be with immersive, real-time voice chat. Launch this sample application and move around a 2D space with dozens of people having conversations.

Your support has been swift, and I regret spending as long as I did trying to get [another solution] to behave itself and not switching sooner. I have, in the past few years, worked with over 9 different VoIP systems besides yours, from Flash based RTMP applications, to deeply integrated "run it over your own messaging stack" SDKs. I have never had as few issues with a voice service, as I have had with High Fidelity.
Adam Frisby
CPO at Sine Wave Entertainment Ltd
I have implemented a lot of software in my life and High Fidelity has been a piece of cake.... Our users are just blown away by the audio experience.
Ara Kevonian
CEO at Soundstage
High Fidelity is far better than anything else on the market.
Eric Pulier
CEO at SpatialWeb
We needed to specify our users' locations without sacrificing the quality of the audio. High Fidelity does that perfectly. I'm so happy.
Soo Ling Lim
CEO at Hubbub
Using High Fidelity means much better audio quality, more accurate 3D sound, lower latency, more cross-browser compatibility, many more simultaneous audio streams per room, and a much better experience for everyone.
