Martin Stig Andersen (born 1973) is a Danish composer and sound designer, best known for his work on the video games Limbo and Inside, as well as contributions to '.
Andersen studied orchestral composition at the Royal Academy of Music in Aarhus, Denmark. After graduating in 2003, he went on to study electro-acoustic composition at City University in London. Andersen cited spectral composers such as Tristan Murail as inspiration.
In 2010, he served as composer and sound designer for Limbo, joining mid-development after an earlier sound designer left the project. For the game, Andersen focused on using abstract sounds to define the game's atmosphere. Following the release of Limbo, Andersen created and directed the audio for Inside and composed the soundtrack with SÃÂS Gunver Ryberg, taking inspiration from 1980s horror films, often using synthesizers. The music was created by routing sound through a human skull, creating a "bone-conducting sound." As the game had closer integration between gameplay and audio, Andersen was more involved with the developers, with the player character's breathing being tied to the chest movement. Andersen was able to suggest changes to the game's structure, allowing the music to provide a coherent build-up. Anderson served as composer for ' alongside Mick Gordon, which released in 2017. Gordon composed music portraying the resistance, while Andersen was tasked with composing music portraying the Nazis and convey the "oppressive marches of the machines." Andersen focused on using non-conventional structure and instruments, aiming for an industrial sound while collaborating with Nicolas Becker to create various foley sounds for the score.
