How RaveSpace Uses ODIN Voice to Make Virtual Experiences Feel Human
Imagine a virtual showroom where LED walls pulse to the rhythm of the music, holograms dance and conversations happen naturally, just like in real life. This isn’t a concert or a party; it’s a browser-based 3D virtual world designed to bring digital experiences to life and provide an immersive, human experience. This is the vision of Frank Hahn, founder of RaveSpace, which is now becoming a reality with ODIN Voice.
RaveSpace: From DJ Equipment to Metaverse Pioneer
Frank Hahn has always understood the importance of exceptional sound. Before founding RaveSpace in 2018, he supplied DJs worldwide with top-tier equipment, enabling them to create audio experiences that move audiences. His philosophy is clear: technology should evoke emotion, not just function.
At RaveSpace, Frank and his team developed the RAVE Engine, a 3D engine for browser-based virtual worlds.
This allows RaveSpace to create virtual showrooms, training environments and live-streamed events - all virtual, yet as engaging and interactive as being there in person. Clients include major global brands such as Deloitte, Samsung, Volkswagen, and Deka.
Still, one challenge remained:
When communication feels unnatural, it’s nearly impossible to create real immersion. We needed a voice solution that feels like a genuine conversation.

Partnership at Eye Level: 4Players & RaveSpace
The solution came through collaboration. At the XR Expo in Stuttgart, Frank met Marco Hirt, Head of Sales & Business Partnerships at 4Players. The connection was immediate.
With 4Players, we found a partner who truly understands and shares our goals
Frank Hahn, CEO, Rave.Space
From this shared vision, a strategic partnership was quickly formed. Instead of providing off-the-shelf solutions, 4Players works closely with RaveSpace to customize the audio experience for each virtual project, ensuring that interactions feel natural and human.
We don’t see ourselves as just a supplier; we’re part of the team
Marco Hirt, Key Account Manager, 4Players
This partnership was key to making ODIN Voice the foundation of immersive virtual world.
ODIN Voice: Spatial Audio for Natural Virtual Interaction
ODIN Voice, which was partly developed by former TeamSpeak experts, delivers low-latency spatial audio that brings virtual worlds to life. Unlike traditional voice chat, it allows natural conversations by simulating the way sound behaves in the real world.
Spatial Audio: Voices come from the avatar’s position within the room.
Automatic Voice Zones: Audio is triggered automatically when users enter defined areas.
Proximity Voice: The Volume dynamically adjusts based on real-world distance.
ODIN Video: Seamlessly enables hybrid meetings and virtual events.
Users love it because it feels natural, not like a tool, but like a real place. It’s the moment when the metaverse becomes human.
Frank Hahn, CEO, Rave.Space
ODIN Voice runs directly in the browser, with no need for downloads or plugins,and integrates seamlessly with the RAVE Engine via a cross-platform SDK and open API, making it easy for developers to embed spatial audio in virtual spaces.
Bringing Digital Worlds to Life
RaveSpace currently uses ODIN Voice in its B2B demo space, where users automatically start audio/video calls in defined zones. ODIN Voice enables spaces where participants can talk spontaneously, as if standing side by side, instead of having silent audiences or chaotic voice chats. Just as in real life, conversations don’t begin by joining a channel; they start naturally when people walk up and begin talking. The initial feedback has been excellent: no dropouts or lag, and above all, impressive sound quality.
ODIN Voice brings real-world functionality to virtual spaces:
Corporate Virtual Events: Participants can converse naturally, just as they would in person.
VR Training & Workshops: Side discussions occur without interrupting the main session, enabling real-time collaboration.
Streamworlds Platform: Live streams become interactive shared experiences rather than passive viewing.
With ODIN Voice, viewers can talk to each other during a stream as if they were right there instead of watching passively
Phillip Schuster, CEO, 4Players
This makes ODIN Voice ideal for virtual conferences, team meetings, product demonstrations, and online workshops.
Technical Highlights for Developers and Studios
ODIN Voice is a high-performance, scalable infrastructure, designed for immersive virtual experiences:
< 50 ms latency on standard European connections
48 kHz audio quality (Opus codec)
Stable performance for 100+ users per room
Scalable to thousands of avatars using gaming-proven infrastructure
GDPR-compliant hosting, all data processed on European servers
You can tell immediately that gaming expertise is behind this. Especially for large events, scalability is a huge advantage.

The Future: Living, Breathing Virtual Worlds
What started as an experiment is becoming a standard for RaveSpace projects. By 2026, ODIN Voice will be integrated into every virtual project, creating spaces that feel just as alive as physical worlds.
The partnership between RaveSpace and 4Players demonstrates how a shared vision, advanced technology, and seamless integration can transform corporate virtual events, online training, and 3D live streams into immersive, human-centered experiences.
“For us, it’s not just a feature,” says Frank. “It’s the moment when the metaverse truly feels human.”
