CaleSon’s facilities include five 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 and Cinema are 5.1 studios : it enabled for the realisation of Evian’s Spiderman advert, the edit of the movie Papicha, Perrier’s hot-air balloons’, Sidaction’s 2017 campaign, Sephora’s campaign..
