Which of the following is NOT typically considered part of a soundtrack?

A soundtrack in video production includes various audio elements that contribute to the overall auditory experience of the project. The main components of a soundtrack typically involve voice (dialogue), sound effects (SFX), natural sounds (NAT), and music. Each of these elements plays a vital role in creating mood, establishing setting, and conveying the story.

Audience participation, however, does not fit within the traditional definition of a soundtrack. It refers to the reactions or interactions of viewers during a performance or event, which are not recorded or added as part of the audio design of a video. This dynamic is more about the context of the viewing experience rather than a composed or designed audio layer that is intentionally crafted as part of the production's sound.

Understanding the distinction between these elements is important in video production, as it helps with audio planning and design, ensuring that all necessary components for a polished final product are correctly identified and utilized.
