Jack Audio Connection Kit: Low Latency Cross-Platform Audio Server

JACK Audio Connection Kit is a cross-platform audio server designed to enable low latency audio connections between applications on Linux, macOS, and Windows systems. It allows audio apps to share audio data in real-time.

What is JACK Audio Connection Kit?

JACK Audio Connection Kit (or JACK) is an audio server designed for low latency audio performance and flexible routing of audio signals between applications and devices. It works by taking over the audio card and providing a common interface that audio applications can connect to in order to share audio data between each other.

Some key features of JACK include:

  • Low latency performance for professional audio applications like recording, effects, synthesis, and live performance.
  • Flexibility in routing audio signals between applications and devices.
  • Synchronous execution of all connected audio applications.
  • Support for a range of OS platforms - Linux, macOS, Windows.
  • JACK runs as a server, which audio applications connect to as clients. This allows them to be executed on different machines across a network if required.
  • Extensibility through support for plugins and session management tools.

JACK is aimed primarily at Linux and macOS platforms for pro audio and MIDI applications. It is commonly used in applications like Ardour, Qtractor, REAPER, Guitarix, etc to enable advanced audio routing options. The low latency performance makes it well suited to live performance software like guitar amp modelers and effect processors.
