# How to Add Custom Round End Sounds in Counter-Strike 2

> Implement high-quality MVP anthems and round-end audio. Learn how to configure sound plugins and FastDL for your Counter-Strike 2 server.

## Enhancing the Atmosphere

Implementing "MVP Anthems" or "Round End Sounds" in Counter-Strike 2 (Source 2) requires a modernized technical approach compared to legacy versions. While the engine natively prioritizes compiled `.vsnd` files, modern server frameworks allow for the real-time decoding of standard `.mp3` and `.wav` assets. This ensures that every match victory or clutch play is accompanied by a stylized audio cue, significantly increasing the immersion and community identity of your server.

## Technical Prerequisites

Before initializing the installation, ensure you have the following components prepared:

* **Audio Assets:** Your files must be encoded in `.mp3` or `.wav` format. For the best performance, use a constant bitrate (CBR) of 128kbps or 192kbps.
* **FastDL Infrastructure:** You **must** use a FastDL (Web Server) endpoint. Unlike some game engines, CS2 clients will not download custom audio assets directly from the game server's binary port.

***

## Deployment Workflow

Follow these steps to integrate custom audio into your gameplay logic.

<Steps>
  <Step title="Initialize Frameworks">
    Ensure your server is running the latest versions of [Metamod:Source](/games/counter-strike-2/how-to-install-metamod-on-a-counter-strike-2-server) and [CounterStrikeSharp](/games/counter-strike-2/how-to-install-counterstrikesharp-on-a-counter-strike-2-server).
  </Step>

  <Step title="Select a Sound Plugin">
    Acquire a compatible CSS sound plugin, such as **Resound** or **MultiAddonManager**, and deploy it to your server's `plugins` directory.
  </Step>

  <Step title="Upload Server-Side Assets">
    In the Game Panel, navigate to `/game/csgo/sound/myserver/` and upload your audio files. This allows the server logic to identify the existence of the files.
  </Step>

  <Step title="Synchronize FastDL">
    Mirror the exact directory structure on your external web server. Upload the same audio assets to the `sound/myserver/` folder on your FastDL endpoint.
  </Step>
</Steps>

***

## Technical Configuration

Locate your plugin's configuration file (e.g., `sounds.json`) and define the triggers for your audio events.

```json theme={null}
{
  "ct_win": "myserver/ct_win.mp3",
  "t_win": "myserver/t_win.mp3",
  "mvp_anthem": "myserver/mvp_track.mp3"
}
```

<AccordionGroup>
  <Accordion title="Resolving 'Silence' Issues">
    If players report hearing no audio at the match conclusion, it almost always indicates a download failure. Verify that your `sv_downloadurl` variable in `server.cfg` exactly matches your FastDL address and that the file permissions on the web server are set to public (Readable).
  </Accordion>

  <Accordion title="Volume & Balancing">
    Most sound plugins allow you to set an internal volume multiplier (e.g., `0.5` for 50% volume). We recommend normalizing your audio files locally before uploading to prevent jarring volume spikes for your players.
