Challenge 2: Why Step 7 Is Called "a Second Pass" — Solution Walkthrough

The answer:

Per OBS Studio's own Chapter 3, the narration audio in this footage
was already cleaned up live, during the original recording session,
using OBS's own Noise Gate and Noise Suppression filters — Noise Gate
silencing background noise during pauses in speech, and Noise
Suppression reducing steady background hum while actively speaking.
That live cleanup is the first pass.

Why Step 7 in this course is genuinely a second pass, not the first:

This capstone's own Fairlight EQ and compression work happens in
post-production, on the already-recorded file — refining audio that
was already reasonably clean from OBS's own live filters, not starting
from raw, unprocessed audio. The two cleanup stages happen at
genuinely different points in the overall production pipeline: live,
during capture (OBS Studio), and afterward, during editing (this
course).

Why this connection matters:

This directly illustrates the two-course connection established
across this subject — OBS Studio's own live audio work and this
course's own post-production audio work are complementary steps in
one overall pipeline, not two competing or redundant cleanup attempts
on the same untouched audio.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise correctly traces the audio-cleanup lineage back through
both courses, confirming that OBS Studio's own Chapter 3 material is
the actual first pass this capstone's Step 7 builds on top of.
