ACID Loops is a technology used with the music making software originally from Sonic Foundry called ACID. Created in 1998, it refers to the repetition, and transposition of sound clips, to form a song. The ACID Pro program is now owned and distributed by Sony, and is on version 7. Sony also now sells a line of Acidized loop sample cds to be used with ACID, as do many third party companies.
Similar technology was added to Cakewalk's Sonar (calling it "Groove Clips") and Cubase (calling it Audio Warp). Although the phrase "acid loops" technically is only associated with Sonic Foundry, some people use the term to refer to the technique even when used with other software packages.
Acidized loops contain tempo and key information, so that ACID can properly time stretch them when pitch shifted.
A website for budding musicians using ACID technology was set up, named ACID Planet.

Famous quotes containing the word loops:
“An accurate charting of the American woman’s progress through history might look more like a corkscrew tilted slightly to one side, its loops inching closer to the line of freedom with the passage of time—but like a mathematical curve approaching infinity, never touching its goal. . . . Each time, the spiral turns her back just short of the finish line.”
—Susan Faludi (20th century)
