> Killing Floor 2 uses the **Wwise** audio engine, which is highly optimized but notoriously difficult to modify server-side. Unlike many Source engine games, you cannot simply upload an `.mp3` to the server and have it play for everyone. Replacing music or sound effects requires a client-side interaction through the Steam Workshop.

## 1. Why Server-Side Audio Fails

The server does not "stream" audio to the client. Most audio is contained in local `.wem` files within the client's game directory.

* If you modify a sound on the server, the client will still hear their local version unless they have the same modded file installed.

***

## 2. The Workshop Solution

The most effective way to implement custom music is via a **Workshop Mod Collection**:

1. Find or create a "Soundtrack Replacement" mod on the Steam Workshop.
2. Add the mod's ID to your server's [Workshop Synchronization list](/games/killing-floor-2/how-to-setup-custom-mapsworkshop-in-kf2).
3. When players join, they will be prompted to download the mod, ensuring that both the server and the client are playing the same audio cues.

  ### XP Warning

  Modifying core game soundbanks can sometimes trigger Tripwire's **anti-cheat or ranking detection**. If you use a "Mutator" to play audio, ensure it is on the **Tripwire Whitelist**; otherwise, your server may become "Unranked," and players will not earn Perk XP.
