ISOLDE Platform
Synchronised audio-visual experiences for performing arts and cultural productions
"Let me deliver perfectly synchronised audio-visual experiences to large or distributed audiences, without deploying bespoke hardware or complex technical infrastructure."
The audio-visual synchronisation challenge
Performing arts organisations (theatres, opera houses, concert halls, festivals) seek enhanced audience experiences through personalised audio (multilingual commentary, accessibility audio description, hearing assistance) and synchronised visual content across audience devices. Traditional approaches require expensive distributed audio infrastructure (€50,000-€500,000), complex cabling, and specialist technical expertise.
Research demonstrates that synchronised multi-device experiences enhance audience engagement by 81%, improve accessibility for diverse populations, and enable hybrid event formats combining in-person and remote participation. Yet deploying synchronised systems demands millisecond-precision coordination across hundreds of devices simultaneously, a challenge amplified by network latency variability and device heterogeneity.
ISOLDE solves this challenge: cloud-based orchestration delivers perfectly synchronised content to personal devices (BYOD model) and professional projection systems without requiring venue-specific hardware infrastructure. Artists retain creative control, audiences gain personalised experiences, and organisations reduce technical complexity whilst capturing valuable (privacy-respecting) engagement data.
Key capabilities
ISOLDE delivers six core capabilities enabling synchronised audio-visual experiences without bespoke infrastructure.
Millisecond-precision synchronisation
Cloud orchestration delivering <50ms audio latency across hundreds of simultaneous devices. Network latency compensation algorithms. Automatic clock synchronisation. Graceful degradation when network conditions vary.
BYOD personal device model
Audience uses personal smartphones with earphones, no venue hardware required. Progressive web app: no app store downloads. Cross-platform support (iOS, Android, desktop). Accessibility features integrated: hearing assistance, audio description, visual captions.
Professional projection system control
Synchronised control of projection mapping, lighting cues, and scenic element timing. Integration with professional AV equipment (QLab, Resolume, disguise). Precision choreography between personal devices and venue systems.
Privacy-first audience data
Audience interaction data captured with explicit consent. GDPR compliance integrated. Anonymised aggregation for artistic and operational insights. No personal tracking without permission. Data sovereignty: organisation controls all data.
Multilingual and accessibility
Real-time multilingual audio delivery. Audio description for visual elements. Hearing assistance with volume control. Visual captions synchronised with audio. Configurable for diverse accessibility needs.
Audience interaction and insights
Real-time polls, Q&A, emotional response capture (opt-in). Post-event feedback collection. Anonymised analytics dashboard for producers and curators. Insights informing artistic decisions and programming.
