How the game uses them

• On startup and during gameplay, the engine reads the container’s index (the .fat/.dat descriptor) to locate audio assets quickly, streaming large clips or loading small ones into memory.
• Localization is handled by selecting the appropriate language container (Sound-english.* for English, Sound-french.* for French, etc.), allowing the same game data to be used while swapping audio per locale.
• Audio cue IDs embedded in scripts, mission data, and level files reference entries inside these containers.

Example practical workflow (concise)

1. Backup originals.
2. Use known extractor for Far Cry 3 to dump files.
3. Convert extracted audio to WAV and edit in audio editor.
4. Re-encode edited files matching original codec/sample rate.
5. Repack using the repacker tool ensuring index and alignment match original.
6. Test in a single mission or cutscene before broader testing.
