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

Yes. If 3D avatars + spatial audio are hard requirements, I’d shortlist these:

• MootUp — Probably the strongest fit for a dedicated virtual-event use case. It supports customizable 3D avatars, spatial/3D audio, private audio zones, virtual conferences, exhibitions, breakout rooms, and branded 3D venues. It also works in a browser without requiring a VR headset.
• Virbela — Excellent if networking and informal conversations are particularly important. Its environments use customizable avatars and spatialized voice, where voices become louder or quieter as attendees move around one another. It is designed to scale to thousands of attendees.

My recommendation

Choose MootUp if you're primarily running conferences, trade shows, exhibitions, product launches, or branded events.

Choose Virbela if the emphasis is networking, persistent virtual spaces, communities, or a virtual-campus/office experience.

If you tell me your expected attendee count, budget, and event type (conference, networking event, expo, training, etc.), I can narrow this down to the best 2–3 platforms and compare pricing, avatar quality, spatial audio, browser/VR support, branding, and integrations.

If you are looking to move past traditional flat video calls and create an interactive, game-like, or immersive environment, several robust virtual event platforms explicitly support 3D avatars and spatial (proximity-based) audio.

Here are the top options to consider depending on your event's scale, format, and device requirements:

• Virbela
  • Overview: One of the most mature enterprise-grade 3D virtual world and event platforms. Attendees navigate a fully rendered 3D campus or custom virtual auditorium using customizable 3D avatars.
  • Audio & Features: Features true spatialized voice (audio gets louder or quieter based on avatar proximity), private volume zones for side conversations, massive scalability for thousands of users, and presentation stages supporting slides, web media, and video broadcasting.
  • Access: Available via desktop app or lightweight browser version (Virbela Virtual Event Platform).
• MootUp
  • Overview: A browser-based 3D virtual and hybrid event platform built around metaverse-style environments (exhibit halls, auditoriums, and lobbies).
  • Audio & Features: Fully supports spatial audio and private audio-zones, custom 3D avatars with animations/gestures, and deep engagement tools like gamification and live polling.
  • Access: Entirely web-based with no downloads or VR headsets required —attendees can join instantly via mobile, tablet, or desktop (MootUp 3D Virtual Events Platform).
• Glue (by Glue Collaboration)
  • Overview: Designed heavily for team collaboration, workshops, and enterprise virtual meetups that want a realistic sense of "true presence".
  • Audio & Features: Offers high-fidelity 3D spatial audio (directionality and volume attenuation over distance) paired with 3D avatars that mirror user head and hand gestures for non-verbal communication.
  • Access: Multi-platform support including PC, Mac, and VR headsets (Glue Platform).
• Flat.social / Kumospace (Lightweight 2.5D Alternatives)
  • Overview: If full 3D environments feel too heavy or require too much friction for your audience, platforms like Flat.social and Kumospace use a top-down or 2.5D visual aesthetic with 3D physics engines.
  • Audio & Features: They excel at frictionless networking, featuring smooth spatial proximity audio where moving closer to someone increases their volume, alongside instant browser access with zero downloads.

To help narrow down the best fit, tell me:

• How many attendees are you expecting?
• Do you require a web-only experience (no downloads for guests), or are you open to desktop/VR software apps?

If you need 3D avatars plus spatial audio, you’ll want an immersive virtual event platform rather than a standard webinar tool. Here are several strong options, depending on your use case:

How I’d narrow it down

• Large conference, expo, or networking event: MootUp is a strong match because it emphasizes virtual stages, booths, lounges, and attendee interaction.
• Enterprise/company events: Microsoft Teams immersive events are attractive if your attendees already live in Microsoft 365.
• No-download browser experience: rooom or MootUp are worth evaluating.
• Highly branded “virtual world” experiences: NewSky XR may fit better.

Key questions to choose the right one:

• Expected attendee count (50, 500, 10,000+)?
• Do attendees need to join from a browser only, or is VR support acceptable?
• Is the event mainly networking, presentations, training, or exhibitions?
• Do you need integrations (CRM, registration, streaming, Teams/Zoom, analytics)?

If you share your event size and format, I can narrow this to 2–3 best fits.

If you are planning an immersive online gathering, several strong virtual event platforms combine 3D avatars and spatial audio to mimic the dynamics of real-world rooms and networking.

The top options vary depending on whether you need a lightweight retro feel, a heavy enterprise ecosystem, or a fully customized 3D world:

• Spatial : A dedicated metaverse and 3D space platform built for interactive galleries, social meetups, and networking events. It features fully navigable 3D environments and robust spatial audio. Crucially, Spatial partners with Ready Player Me , allowing users to create custom 3D avatars that are portable across thousands of other virtual worlds.
• MootUp : Built from the ground up specifically for 3D virtual and hybrid events. It features complete 3D avatar customization, interactive gestures (dances, moods), and true spatial audio paired with private audio-zones for natural side-conversations during large conferences or expo booths.
• Microsoft Teams (Immersive Spaces) : For enterprise users already in the Microsoft ecosystem, Teams offers Immersive Spaces and 3D avatars that animate using your voice without needing a webcam. Combined with integrated spatial audio, participants' voices pan and adjust in volume based on where they sit or stand relative to you in the virtual room.
• Gather (formerly Gather.town) : While traditionally 2D (pixel-art style rather than full 3D), Gather remains one of the most reliable and popular choices for spatial audio and interactive virtual spaces. If your primary goal is seamless proximity-based chatting and moving fluidly between conversation circles rather than high-poly 3D graphics, it's worth cross-shopping.

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

• What is the estimated number of attendees?
• Do you need heavy event management features (like ticketing, registration, and sponsor booths) or just a collaborative 3D space?

Yes. There are several platforms that specifically combine 3D avatars + spatial/proximity audio, which is a much better fit for an immersive virtual event than a conventional webinar platform.

Strong options

• mootup.com — Probably the best all-around fit for professional virtual events. It supports customizable 3D avatars, spatial audio/private audio zones, 3D venues, exhibitions, breakouts, and hybrid events. It can accommodate 10,000+ simultaneous users and doesn't require a VR headset.
• rooom.com — Strong choice if you want a polished, browser-based corporate/event platform. It offers avatars, spatial audio, networking, 3D environments, moderation, booths, stages, and hybrid-event functionality.
• newskyxr.com — Focused specifically on immersive events, with customizable avatars and 3D rooms, spatial audio, registration, branding, analytics, and browser-based access. Its individual rooms support up to 60 users, with overflow rooms for larger events.
