The Jack Audio Connection Kit is a Linux program that acts as a middleman between other programs by allowing audio data to be transferred in real time between programs that both utilize Jack. It specializes in low latency. This means there is no perceptible time delay between the audio input from one program and output of the other. Jack is used by musicians recording and editing audio on Linux systems. It can also be used by programs that work with DJ equipment and programs that create sound effects.
