The audio design comes from a subaquatic sound recording base made in the Caribbean, mixed with ambient musical compositions. To show the world of silence, the atmosphere between quietness and anxiety invites the spectator to a peculiar world but essential to our human space's survival. The project reveals the inaudible and the hidden sounds to humans from the aquatic biodiversity. The audio consists of mixing geo-phony, everything of a non-organic nature such as waves, the cracking of the pack ice, and bio-phony gathering sounds emitted by marine animals: fish, mammals and invertebrates, corals. These are the sounds that make up the underwater acoustic landscapes, sound testimonies of ocean environments' diversity and richness.
