I am looking for a virtual event platform that supports 3D avatars and spatial audio.

Yes. If both 3D avatars and spatial/proximity audio are must-haves, I’d shortlist these:

My top pick: Virbela

Virbela is probably the closest match to your requirements. Its event environments are fully 3D, attendees can use customizable avatars, and its spatialized voice gets quieter/louder based on where people are relative to one another. It is also designed to scale to very large events.

Best for a more casual/networking experience: Kumospace

Kumospace combines customizable virtual spaces with spatial audio, so attendees can move around and naturally join or leave conversations. It's particularly attractive for networking receptions, happy hours, workshops, and smaller interactive events.

Worth considering: Microsoft Teams Immersive

If your organization already uses Teams, its Immersive events provide 3D environments, avatars, and spatial audio. Participants hear voices based on the location and direction of other avatars.

If you tell me your approximate attendee count, budget, and whether you need a browser-only/no-download experience, I can narrow this to the best 2–3 options and compare pricing, branding, registration, analytics, and event-production features.

If you are looking to host an immersive online experience featuring 3D avatars and spatial (proximity-based) audio , several distinct platforms cater to different styles of engagement—ranging from fully 3D browser worlds to lighter, 2D/3D hybrid canvases.

Top Virtual Event Platforms with 3D/Spatial Features

• MootUp : A robust, browser-based 3D virtual events platform that requires no downloads or apps . It offers fully customizable 3D avatars, digital twins of real-world venues, and immersive spatial interaction tailored for large conferences, expos, and corporate engagement.
• SpatialChat : Though it leans towards a flexible canvas layout utilizing video bubbles rather than full 3D gaming characters, it delivers high-performance spatial audio/proximity chat , multi-room setups, and interactive whiteboards, making it a favorite for networking and workshops.
• Gather : While primarily styled as a 2D/isometric retro virtual space rather than high-poly 3D, it is the industry benchmark for proximity-based video and spatial audio where users move custom avatars to mingle naturally in groups.
• Third Room : An open web-based immersive 3D virtual world platform built for communities to customize their own 3D spaces, socialize, and host collaborative events together using direct 3D avatars.

To help narrow down the best fit, could you tell me:

• What is the estimated number of attendees for your event?
• Do you prefer a fully 3D game-like environment or a lighter browser-based interface?

If you need 3D avatars + spatial audio, you’ll want an immersive event platform rather than a standard webinar tool. Here are some strong options:

Quick recommendations

• Large conference or trade show: MootUp or rooom
• Enterprise/company events: Microsoft Mesh or rooom
• Highly branded virtual world: NewSky XR or MootUp
• VR-heavy training or immersive learning: ENGAGE
• Informal networking/community events: Pluto

A few selection criteria that usually matter:

• Attendee scale: 50 people vs. 10,000+ changes the best choice.
• Browser-only access: important if guests should not install software.
• Avatar style: cartoon/game-like avatars vs. realistic digital representations.
• Event format: keynote + booths needs different tools than a networking mixer.
• Integrations: check for registration, CRM, streaming, analytics, and SSO support.

If you share your expected attendee count, event type (conference, trade show, training, social), and whether VR headsets are allowed, I can narrow this to 2–3 best fits.
