The tonwelt supraCMS is at the heart of our modern end-to-end solution. Here you can create multilingual, interactive tours for all target groups – with digital storytelling, automatic triggering, synchronized audio and video content, AR integration, indoor navigation and external web content. Tools such as live notifications, maps, routing, multitrack player, quiz, surveys and various design elements enables a completely new visitor experience. 

Regardless of the device used – whether audio guide, media guide, native app or PWA – you can manage your content centrally and update it across platforms. supraCMS is the most powerful and sophisticated solution for innovative visitor tours.

Audio guides are essential tools for communicating exhibition content effectively because they provide structured storytelling and allow visitors to explore exhibitions at their own pace. Moreover audio guides are meanwhile the key of non-personalized interpretation in museums and enables also visitors in other languages or special needs to learn more about your exhibition.

They support multilingual access, improve accessibility, and offer interactive features that increase visitor engagement and satisfaction, resulting in a more comprehensive and enriching museum experience.

For some museums, the hire of audio guides is a key financial consideration, whilst others use audio guides as a primary information tool or integrate them seamlessly into the exhibition experience to offer a modern, interactive visitor experience.

The reasons for choosing an audio guide in a museum are therefore very varied. However, the added informational value and the opportunity to provide visitors with a curated and verified information tool are now of great importance.

No, the tonwelt audio and media guide devices work without an internet or streaming connection. No internet connection is required during the service. However, an internet connection to the CMS is required for content upload and deployment, as well as for the collection of statistics.

tonwelt devices are designed to be durable, lightweight and easy to maintain. Additional technical support and service packages are available to ensure long-term reliability. Regular maintenance can significantly increase the products' lifespan.

Yes, Tonwelt offers mobile apps that allow visitors to access digital audio tours directly on their smartphones. The multi-platform content management system, supraCMS, supports browser-based applications (PWAs) and native applications for iOS or Android.

Triggering (automatic activation of content or commands) on the supraGuide ECO and supraGuide SPHERIC requires additional hardware in the form of triggerPoints, which are reliable solutions that have been successfully tested worldwide for point-and-play, tagging, and automatic playback. They can also be used with the supraGuide DIVA. For the supraGuide DIVA, we also provide a software-based virtual triggering solution that does not require any additional hardware. However, triggerPoints are mandatory as soon as AV-Synch is required.

Yes, we provide outdoor, GPS-based triggering for iOS and Android applications. However, the GPS-based automatic triggering for PWAs is technically highly limited. We do not recommend this solution.
