Figure 1.54 Ardour, free digital audio processing software for the Linux or OS X operating systems
Ardour works in conjunction with Jack, an audio connection kit, and the GUI for Jack,
qjackctl. A screenshot of the Jack interface is in Figure 1.55. On the Linux platform, Jack can
talk to the sound card through ALSA, which stands for Advanced Linux Sound Architecture.

ALSA and OSS, both illustrated in Chapter 2 examples.
