Challenge 2: Handing Off Narration to a Video Project — Why WAV Beats MP3 — Solution Walkthrough

The answer:

This narration isn't heading to a listener yet — it's heading into
further editing, inside a video project's own Fairlight page. Per this
chapter's own material, WAV is the better choice for exactly this kind
of handoff, since the video editor will process the audio further
before anything is finally delivered to an audience.

Why exporting as MP3 first causes a real problem:

MP3 is lossy — some audio data is already discarded to shrink the file
at 128 kbps. If that lossy file is then imported into Fairlight,
processed further, and eventually exported again in whatever format
the finished video ends up using, the audio has now been compressed
twice, compounding quality loss that a single, final compression pass
wouldn't have caused.

Why WAV avoids this:

Since WAV is uncompressed, no audio data is thrown away before the
video editor gets to work on it. Whatever compression the audio
eventually goes through happens exactly once, at the video's own final
export stage, rather than being layered on top of an already-lossy
MP3.

WHY THIS WORKS AS AN ANSWER
------------------------------
This exercise checks that WAV is correctly chosen for a handoff into
further editing, specifically to avoid stacking a second, unnecessary
round of lossy compression before the audio's actual final export.
