Sigma Sound Studios was a recording studio in Philadelphia, Pennsylvania. It was founded in 1968 by recording engineer Joseph Tarsia.[1]

Located at 212 N. 12th Street in Philadelphia, Pennsylvania,[2] it was one of the first studios in the country to offer 24-track recording and the first anywhere to successfully employ console automation. Tarsia, formerly chief engineer at Philadelphia's Cameo-Parkway Studios, also opened Sigma Sound Studios of New York City in 1977, at the Ed Sullivan Theater building.

From its beginning, Sigma Sound was strongly associated with Philadelphia soul and, in the 1970s, the sound of Gamble and Huff's Philadelphia International Records (its driving rhythm a precursor to disco music), as well as the classic, sophisticated productions of Thom Bell. Both featured large productions with strings and horns creating what became known as the "Philadelphia Sound". Their success attracted many artistes and producers from various music genres across the US, as well as Europe and Japan. By the late 1970s, Sigma was operating 10 music rooms on a 24-7 schedule. Sigma's long-time general manager, Harry Chipetz, managed the business operations and worked hand-in-hand with Tarsia in developing a staff that numbered close to 50 at its peak. Sigma is credited with well over 200 gold and platinum awards with an extensive client list that begins with Aretha Franklin and ends with ZZ Top.

David Bowie recorded much of his album Young Americans in August 1974 at Sigma Philadelphia. Madonna used the New York studios to record her 1983 debut album, Madonna. On April 15, 1972, singer-songwriter and pianist Billy Joel played an hour-long concert at Sigma Studios. The recording of "Captain Jack" from this event received extensive radio play in the Philadelphia area, long before Joel became widely known, which helped him establish a national following.

Tarsia sold the New York studios in 1988 and then sold the 212 N 12th Street location in 2003, but they still retained the Sigma Sound Studios name. The 6,000 unclaimed tapes from Sigma's 35-year-old tape library are now part of The Drexel University Audio Archive. Much of Sigma Sound Studios history can be found in the Temple University Library Archives.

It was reported in the April 2015 issue of Pro Sound News, (a NewBay Media publication), that "the building that houses the historic Sigma Sound Studios in Philadelphia has been sold for $1.55 million, with the intention of renovating the space for office, retail or residential use." The studios had closed for business in 2014, according to the website. When checked on April 9, 2015, the Sigma Sound Studios website, was still available for viewing, but shows no current information on the studio's status and seems to have been last updated in 2013.
