EU4 Soundtrack for EU5
Brings the music of Europa Universalis IV into EU5 — fully integrated into the game’s dynamic music engine. War, peace, and cultural context all trigger the right tracks automatically, just like in the original games.
179 tracks from EU4 and its music DLCs are woven into EU5’s adaptive music system:
- At war — EU4 war tracks play alongside EU5 music
- At peace — EU4 ambient and atmospheric tracks
- Cultural context — regional EU4 music matches your nation’s culture group:
- European nations hear British, French, HRE, Scandinavian, Russian, Iberian tracks
- Ottoman/Persian/Egyptian/Caucasian → Middle Eastern tracks
- Chinese/Japanese/SEA → East Asian tracks
- Indian, African, American nations get their own regional tracks
EU4 track names won’t appear in the Music Player list. The music plays automatically in the background based on game state — you’ll just hear it change. You can still skip to the next track using the Next button in the Music Player. This is intentional to keep the mod multiplayer-compatible (no checksum change).
1. Europa Universalis IV must be installed on the same Steam account.
The mod reads audio files directly from your EU4 folder — it does not download or redistribute any music.
Only tracks from DLCs you own will be included.
2. Wwise Authoring Tools 2026.x (free)
Required to convert EU4 audio to EU5-compatible format (WEM).
No longer required — the setup script handles conversion automatically.
3. FFmpeg
Audio conversion tool. Install via terminal:
Or download from https://ffmpeg.org and add to PATH.
Step 1. Make sure requirements 1 and 3 above are installed.
Step 2. In Steam → right-click EU5 → Properties → Launch Options, paste:
Step 3. Launch EU5. A setup window will appear and convert all EU4 tracks (~2–5 minutes). The game starts automatically when done.
Step 4. Once in the game, open the mods menu → enable EU4 Soundtrack for EU5 → restart the game.
After the initial conversion the launch command and FFmpeg are no longer required — the mod works without them. You can uninstall them, or keep them if you want the setup to automatically sync any new EU4 tracks added to your game folder.
EU5 uses Wwise for its entire audio system. This mod patches the Wwise sound banks at the binary level — adding EU4 track references into EU5’s existing WAR, PEACE, and cultural playlists. No EU5 tracks are replaced or removed.
- WAR — +146 EU4 tracks (player at war)
- PEACE — +135 EU4 tracks (player at peace)
- European culture — +43 tracks
- Middle Eastern culture (Ottoman/Persian/etc.) — +19 tracks
- East Asian culture (Chinese/Japanese/etc.) — +15 tracks
- Indian culture — +5 tracks
- African culture — +4 tracks
- North American culture — +4 tracks
- South American culture — +1 track
Neutral and discovery tracks appear in both WAR and PEACE playlists, so they play regardless of war state.
Regional tracks (British, Ottoman, East Asian, etc.) are added to both the WAR/PEACE playlists and their matching cultural playlist — so they play roughly twice as often as neutral tracks for nations of that culture.
Tracks from any of these DLCs you own will be automatically included:
Base Game · Songs of the New World · Republican Music · Songs of War · Guns Drums & Steel Vol. 1–3 · Songs of Exploration · Kairis Soundtrack Parts 1–3 · Songs of Regency · Rule Britannia · Dharma · Golden Century · Emperor · North America · South-East Asia · West Africa · East Africa · Scandinavia · Baltics · Ottoman · Chinese · French · Egyptian · Persian · Caucasian · Utopia HRE · 10th Anniversary · The Rus Awaken · Kairis Ottoman Tunes · Native America · Central Asia · Central Europe
Not included: Sabaton Soundtrack, Fredman’s Epistles — these contain third-party licensed music and cannot be redistributed or converted.
"Game crashes when clicking Accept with mod checked in the mod menu" — Try changing the mod’s load order. Place EU4 Soundtrack for EU5 earlier in the list — this usually fixes the crash or try another order. After changes restart the game as well.
"FFmpeg not found" — Run
in PowerShell, then restart Steam
"EU4 not found" — The script finds EU4 automatically through your Steam library. Make sure EU4 is installed on the same Steam account and that Steam is installed.
"packed_codebooks.bin download failed" — Check your internet connection. The file (~74 KB) is downloaded automatically on first run from github.com/hcs64/ww2ogg
Only a brief sound then silence — Delete all .wem files from the mod’s Media folder and re-run the setup script to rebuild the media cache.
Music not playing — Make sure the mod is enabled and the game was restarted after enabling it
After a mod update it is recommended to re-run the setup script once to ensure full compatibility — the script will only convert new tracks and skip everything already done.
