Sigma Sound Studios was an American independent recording studio in Philadelphia, Pennsylvania, founded in 1968 by recording engineer Joseph Tarsia. Located at 212 North 12th Street in Philadelphia, Sigma Sound is closely associated with Philadelphia soul, and was the location of numerous recordings of Gamble and Huff's Philadelphia International Records, the group of session musicians known as MFSB, and producer Thom Bell.

Sigma Sound is credited with well over 200 gold and platinum awards with an extensive client list that includes Harold Melvin & the Blue Notes, The O'Jays, The Spinners, MFSB, David Bowie, Teddy Pendergrass, Patti LaBelle, The Roots and others.^[1]

From 1977 through 1988, the studios also operated a New York City location in the Ed Sullivan Theater building, which hosted recording projects by artists including Talking Heads, Madonna, the Ramones, Aretha Franklin, and the B-52s.
