CaleSon’s facilities include four studios. Fully dedicated to musical composition, completely analog, if CaleSon was a city, studio A would be its historical centre: laboratory and nerve centre of musical creation, Christophe and Yoan collaborate there, one behind the console, the other at the microphone. Studios B and D are custom built for publicity postproduction, it is here that voice-overs are recorded, sound design and sound effects created, and that the mixing takes place. Lastly, studio C is a 5.1 studio : it enabled for the realisation of Evian’s Spiderman advert, Perrier’s hot-air balloons’, Sidaction’s 2017 campaign, Sephora’s campaign.. A tool bound to develop increasingly.
