Amon Adonai Santos de Araújo Tobin (born February 7, 1972), better known as Amon Tobin, is a Brazilian electronic musician, and DJ. He is best known for his use of sampling. Tobin is also credited with helping to create the emerging "trip hop" genre in the late 1990s. He has released seven major studio albums since 1996 under the London-based Ninja Tune record label where he is considered one of their most successful artists.

In 2005, he created the musical score to Ubisoft's critically acclaimed and successful video game Tom Clancy's Splinter Cell: Chaos Theory. He is also noted for his entirely field-recorded album Foley Room, released in 2007. His music has been used in numerous major motion pictures including The Italian Job and 21. Tobin has created songs for several independent films, including the 2008 Hungarian horror film Taxidermia.

Born in Rio de Janeiro, Brazil, he began his career in Brighton, England with his debut album Adventures in Foam. As of 2008 he continues to produce music and collaborate with other artists.

In 2002, Tobin relocated to Montreal, Canada where he had spent time previously at Ninja Tune's North American Headquarters. As of 2008, Tobin lives in the industrial area of Old Montreal to avoid noise complaints from neighbors after dark. There he produced his fifth album Out From Out Where released that same year. This was his first album created primarily in a professional studio. He later released a single, Verbal, taken from Out From Out Where. Otis Hart of Dusted Magazine said that Tobin's style of producing had come into its own. He acclaimed Tobin's "refined sense of tempo" compared to his previous albums.

In January 2004, Tobin was contracted by video game company Ubisoft Montreal to compose the soundtrack for the third installment of their critically successful Splinter Cell series, Tom Clancy's Splinter Cell: Chaos Theory. To facilitate using the music in a video game, where the level of action or plot can change in real-time, each track was broken down by Tobin into four distinct but similar parts based on their level of intensity. The game's developers could then use each section to provide music based on the actions of the player. The album continued the trend Tobin started with Out From Out Where, as he used more original samples during production. In addition to being included with the game, Ninja Tune released the score as an individual album in 2005, titled Chaos Theory - Splinter Cell 3 Soundtrack, several months before the game's release. It was received well, benefiting from a wider audience of reviewers in both the music and gaming industries. Ben Hogwood of MusicOMH.com applauded Tobin's use of melody and texture, adding that he controlled the sounds with the "clarity of a classical orchestrator." He later recorded a Dolby Digital 5.1 surround sound version of the album with audio engineer Bobby Azinsky in a dedicated Solid State Logic studio in Los Angeles.

Tobin's sixth studio album, Foley Room, was released in 2007. The title alludes to the "foley rooms" used by recording engineers and foley artists to record sound effects in the movie industry. On this album, Tobin concluded his transition away from prerecorded source material that started with Out From Out Where. All of the samples used for production were recorded by himself using an omnidirectional microphone. Recorded primarily in Montreal, San Francisco, and Seattle, the samples came from a wide range of sources including motorbikes, tigers, insects, and water falling from a tap. Also contributing to the album were the string quartet Kronos Quartet, drummer Stefan Schneider, and harpist Sarah Pagé. Foley Room's use of field-recordings was used to help promote the album, including two official pre-release trailers posted to YouTube. Nate Dorr of PopMatters.com called it a "smooth, natural progression" from his work on Supermodified. The first single, "Bloodstone", was released to the iTunes Music Store months before the rest of the album. Ninja Tune also published a DVD titled Foley Room: Found Footage which documented the recording process.

In 2008, Tobin announced he was working on a new video game soundtrack for an "undisclosed PS3 title".

Not having any previous experience as a nightclub disc jockey (DJ), Tobin began performing live shows in clubs with other Ninja Tune artists after releasing his second album, Bricolage. His shows generally contain music that he has produced during his career, mixed with modified songs from drum and bass, hip-hop, or other genres. Although his music is primarily produced in a studio with samplers and other equipment, Tobin is not considered a Live PA performer who creates music live on-stage with those instruments. He is known for building Dolby Digital 7.1 surround sound speaker systems during his performances.

Tobin has performed individual shows in many countries including tours in Europe, Australia, Japan, and the United States. His 2003 live performance in Melbourne, Australia was used for the fourth album in Ninja Tune's Solid Steel series because Tobin was not available to record a studio mix at the time. Many songs from the original recording were omitted because of copyright issues with the original artists, including the R&B group Destiny's Child.

A second Solid Steel album was recorded in Brussels at the Ancienne Belgique in 2007 and was released for free in November 2008. According to Tobin's official website, "After months of back and forth and despite everyone’s best efforts the mix was in danger of being edited into the ground to accommodate big labels and publishers. Rather than release a compromised version commercially, the decision was made to give it away for free instead."
