This reminds me of the recent research where the texture of food was changed by playing sounds in headphones while the subject chews the food. (e.g. playing a crunching sound would make vegetables seem fresher)<p>Since the film editor isn&#x27;t a brain scientist, I presume he&#x27;s using the term synesthesia quite broadly to describe these sort of sensory interplays that are apparent to him but have barely been explored by researchers.
