Less than 100 years ago, movies were silent. We’ve come a very long way since The Jazz Singer (1927, Warner Bros.), and great audio now plays a huge role in video production. Vizrt live production systems provide an extensive set of professional quality audio tools, which we’ll explore in this chapter.

External audio connections and basic configuration were touched on in Input Connections and Output Connections. A tabbed pane labeled Audio Mixer, found just below the main Switcher presents more precise control over individual audio sources and outputs.

Compact sub-panels in this pane provide configuration and control for individual audio sources and also audio outputs as follows, from left to right:

• External audio sources: Audio INPUTS 1-16.

• Internal sources: Media Players, and Effects (sound embedded in Animation Store transitions).

• Stream: Controls streaming output to the web.

• Aux 1 to 3: Controls for Aux audio busses.

• Phones: Volume control for the system’s headphone output.

• Master: Controls the primary audio bus.

Audio level control for individual recorders are provided elsewhere.
