QuikQuak has announced Copula, which is described as "a time stretching and pitch shifting engine like no other". They continue: "It completely separates the notion of time and pitch and allows you to move freely and smoothly between the two, in glitch free real-time. Notable for its transient accuracy, and bass stability, Copula has a larger pitch range, and more natural time stretching than the best algorithms available today. The demo is a small stand-alone PC executable, that lets you load Wave files and control their time and pitch independently. It comes with a selection of test audio files. Copula makes it seem easy, but it took a long time to create."
Copula will be available for licensing soon - all enquiries are welcome.
