There are many aspects to making a film – the actors, the script, the director, the music – but there is another aspect many people forget about: the sound mix. The process of combining an actor’s dialogue and the music with the ambient noises and sound effects is an art in its own right, but when doing so for a film filled with murders and hauntings, this process becomes all the more compelling and off-putting. The Berberian Sound Studio is located in Italy, and English sound engineer Gilderoy (Toby Jones) makes the trip to help create the mix for a pulp film from the eccentric director, Santini (Antonio Mancino). On the surface, a man coming to a new country may seem like a story about learning from different cultures and their various creative personalities, but the narrative takes a decidedly sinister turn when the sounds Gilderoy is creating for the film seem to follow him from his recording sessions into his actual life.
