On the occasion of the celebration of the French National Day 2021<\/strong> in Orl\u00e9ans<\/strong> , the traditional pyromusical fire<\/strong> had to be adapted to the health constraints in force.<\/p>\n\n\n\n

The cancellation of this event was not an option, both for the municipality of Orl\u00e9ans and for its spectators, but there was however no question this year for the municipality to propose a gathering of spectators <\/strong>at the ends of europe bridge<\/strong>, from which fire would be drawn.<\/p>\n\n\n\n

The sound diffusion<\/strong> could not be done with a traditional sound system<\/strong>, but thanks to a device <\/strong>which would allow spectators to be autonomous <\/strong>in L'listening to the soundtrack<\/strong> a spectacle.<\/p>\n\n\n\n

It is in this perspective thatElectroson Studio<\/strong> took up the challenge, proposing a completely dematerialized solution <\/strong>guaranteeing a optimal quality of audio transmission<\/strong> and the minimal latency<\/strong> in the communication <\/strong>and the synchronization <\/strong>with the pyrotechnic system for this 20-minute show which usually brings together 20,000 spectators<\/strong>.<\/p>\n\n\n\n

USER EXPERIENCE<\/h2>\n\n\n\n
<\/div>\n\n\n\n\n\n\n\n
<\/div>\n\n\n\n

The soundtrack<\/strong> pyromusical fire was listenable during the event on the website<\/strong> july13pontdeleurope.fr<\/a>, reachable without the need to install an application<\/strong>, on connected devices, such as smartphones <\/strong>Where tablets<\/strong>. This web interface is compatible with the main operating systems (android <\/strong>and iOS<\/strong>). Its use is free <\/strong>for the viewer, and free of rights and access<\/strong>.<\/p>\n\n\n\n

A few days before the event, spectators are invited to visit the website so that the soundtrack of the fire is automatically preloaded in the background <\/strong>(no user action required).<\/p>\n\n\n\n

A simple connection to the website <\/strong>a few minutes before the start of the pyromusical fire allows the automatic trigger <\/strong>soundtrack from the start of the show.<\/p>\n\n\n\n

TECHNICALLY<\/h2>\n\n\n\n
<\/div>\n\n\n\n

HAS the precise moment <\/strong>where the show is started by the fireworker, the fire firing system sends out a pulse (called a time code<\/strong>) to our device which automatically synchronizes<\/strong> and inform via 4G network<\/strong> all viewer connected devices. The soundtrack then begins to play on the viewers' devices.<\/strong>.<\/p>\n\n\n\n
