Abstract: This proposal tries to answer the need to free the movement of the voice of the characters in the surround soundscape, following the action or the creative needs of a movie. — The system makes use of a series of sensors and receivers on location that allows the recording of the real time position of a sound source and its relationship with the camera. During postproduction, this data is applied to the individual tracks to recreate the same spatial relationships in a three- dimensional soundscape. Since the data is recorded separately from the audio, it can be applied to the dubbed versions of the film. — A second problem we face is that all the detailed work the sound engineers do to recreate the acoustics of a given space -the location of a scene- by the means of adding reverb or a particular equalization, is lost in the foreign language versions of the film. — The system is also a method to define a physical space by its acoustic characteristics, information that can be incorporated further down the postproduction process and in the exhibition and streaming phases and taylor it to the unique environment of the final user.
