The Platform
Cloud orchestration, mobile applications, and projection control architecture.
Distributed Synchronisation Architecture
Isolde platform combines cloud-based timing orchestration, mobile audience applications, and professional projection control to deliver perfectly synchronised audio-visual experiences across hundreds of devices simultaneously. The architecture is designed for reliability, scalability, and sub-50ms timing precision.
Core Platform Components

- •Session management and device registration
- •Analytics aggregation and export
Mobile Audience Application
Progressive web app delivering synchronised audio, video, text, and interactions to audience personal devices.
- •Cross-platform (iOS, Android, desktop browsers)
- •Adaptive streaming (HLS) with quality selection
- •Offline content pre-caching
- •Real-time interaction UI (polls, reactions, open text)
- •Accessibility features (captions, audio description)
Projection Control System
Professional display management for supertitles, subtitles, visual content, and environmental projection.
- •Multi-output video routing
- •Resolution and aspect ratio adaptation
- •Colour calibration and brightness control
- •Fallback and redundancy mechanisms
- •Operator interface for live control
Real-Time Interaction Engine
Bi-directional communication capturing audience feedback and enabling live participation.
- •Configurable interaction types (polls, emoji, free text)
- •Real-time aggregation and visualisation
- •Moderation and filtering controls
- •Export to CSV/JSON for post-event analysis

Why This Architecture
Scalability
Cloud-based orchestration scales from intimate performances (50 devices) to festival environments (2,000+ devices) without infrastructure changes.
Reliability
Redundant timing servers, CDN-distributed media, and automatic failover ensure uninterrupted experiences even during network variability.
Accessibility
Progressive web app runs on audience personal devices without app store downloads, enabling instant participation and multilingual experiences.
