Michel Chion is a french experimental music composer, recognized for working along Pierre Schaeffer in the development of Musique Concrete, coming up with theories of the relationship between sound and film. He wrote one of the most important books in film audio theory called Audio-Vision (1994), in this text Chion presents concepts such as Acousmétre and Added value, techniques that have remained relevant throughout contemporary film. As mentioned before, Chion was deeply influenced by Musique Concrete and his works follow the methodology of french avant-garde music. It’s really interesting to see how early tape manipulation and experimentation formed the building blocks of the audio-visual practice.

I found this lecture from Michel Chion, published by Liquid Architecture (2017), where he explains in depth his works and experiences. I found this video very informative and interesting.
