Integra Live is an application that makes it easy to use interactive audio processing to create new music. With Integra Live you don’t have to write code or patch objects to
create interesting live processing. Neither do you have to deal with the
complexities of finding, loading and learning external plugins. The
software provides a library of built-in audio processing modules that
offer everything you need to get started with interactive audio.
