The process
In this story there are two sound spaces: the real one and the aquatic one. The protagonist is linked through this strange world through the orifices of her house until she becomes trapped in it. The idea of this design is to find a way to give the sound the quality of an enclosure, a hole, a tube. This is how the idea arose, following the premises of sound designer Walter Murch, the worldizing.
What is worldizing?: It is an analog technique for spatializing sound. It is achieved by recording a sound in a studio, then reproducing that signal in another particular environment, recording it again in that second environment, resulting in the original signal plus the acoustic reflections of a particular place.
So what we did was record sounds and then play them back inside tubes to record them again with their new acoustic quality. The tube served as an analog filter, managing to link the idea of sound design with the audiovisual narrative: The element that we use as a design tool ends up being the protagonist of the audiovisual narrative.
