📋 About This Mod
DSSI can be used to swap out in-game sound effects & music contained in .fsb files with custom sound effects & music.
Seeing as the FSB files of DS and DS:R are identical, sound mods are not only supported in DS:R, but the same, already existing mod files work with it as well.
Notable sound mods created with DSSI:

✨ Key Features
📊 Pros & Cons
✅ Pros
- Community-approved: 755 endorsements from fellow Dark Souls modders.
- 15,618 downloads means it's battle-tested across tons of audio swap projects.
- v2.1 added DS3 encrypted file support and better FSB rebuilding, fixing the biggest pain points.
⚠️ Cons
- Last updated in 2018—no stated support for Dark Souls Remastered's changes.
- Audio-only tool; won't touch textures, models, or gameplay.
- Manual file handling with no mod manager integration mentioned—you handle backups yourself.
For Dark Souls modders who want to replace boss music with custom tracks or create full audio overhauls. For players who want specific sound swaps without rebuilding the game. Skip if you need a general mod manager or non-audio mods—DSSI is strictly a sound tool.
💡 Beginner Tips
- Use DSSI's built-in extract feature to pull the original sounds first so you have clean backups of every file you replace.
- When modding Dark Souls III, test a single encrypted file swap before batch importing to confirm the FSB rebuild works on your setup.
- Drag and drop multiple files for speed, but keep a list of what you changed in case the game audio glitches after a swap.
