Spitfire Audio works with composers, producers, engineers and studios to create realistic recordings of instruments and libraries of music samples. The digital sounds can be downloaded to a computer and enable people to compose and perform music. The North London company was co-founded by award-winning composers Christian Henson and Paul Thomson in 2007 and the pair have collaborated with the likes of Hans Zimmer and the London Contemporary Orchestra. Spitfire Audio sounds have appeared in major Hollywood film scores as well as in recordings by Radiohead and U2.
