Challenge 2: Ducking in Audacity vs. Fairlight — Same Idea, Different Situation — Solution Walkthrough

The answer:

The core idea is identical in both places: automatically (or manually)
lowering a music track's volume specifically during moments when
speech is present, then letting it rise back up during pauses or once
the speech ends. Video Editing Fundamentals' own Chapter 7 described
this exact concept inside Fairlight.

What's different is the situation it's applied in:

In Fairlight, ducking happens on tracks synced to a moving video
picture, often as part of a larger multitrack production with fader
automation built for that video-synced context. In Audacity, per this
chapter, ducking (or an equivalent manually-drawn volume envelope)
applies to a small, standalone pair of tracks — narration and music —
with no video timeline involved at all.

Why this isn't two different concepts:

Both are the same underlying technique — automatically prioritizing
speech over background music — just applied at two different scales
and in two different contexts: one video-synced and multitrack, one
standalone and simple.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise checks that ducking is correctly recognized as the same
underlying concept in both courses, with the actual difference located
in scale and context (video-synced multitrack vs. standalone simple
mix), not in the technique itself.
