Prospect TV is a production company based in Berlin that we have already worked with. They contacted us with a technical request that is familiar to us: creating the sound effects for a series of three 52-minute wildlife documentaries broadcast on Arte and HBO Max. Despite our common experience, it presented itself as a new challenge. From sounds emitted by marine animals to the sound of the wind, we had to adapt. Indeed, it is not easy to reproduce animal sounds in their environment. To help us, the Seaquarium du Grau du Roi opened its doors to us. Using a boom pole, we recorded seals jumping in their pool.
