YouTube Audio Snippet Extraction

I need the music lifted from three separate YouTube videos, but only the exact sections I will specify. Once I send you the links and timestamps, please grab those segments, trim them cleanly, and return one MP3 file per video.

The default bitrate can be 320 kbps unless you advise otherwise. Normalise the volume so all three tracks sit at a consistent level and remove any leading or trailing silence.

Deliverables
• 3 trimmed, high-quality MP3 files (one per video)
• File names that clearly reference the original link or track order

FFmpeg, youtube-dl (yt-dlp), or similar is fine as long as the final audio is artefact-free. Let me know if you need anything else before starting.
