CS2 Looping music

This guide prepares looping music, ambient radios, and soundscapes for Counter-Strike 2.

This guide is made using Hammer 5 Tools, with its Audio Editor for the loop marks and its SoundEvent Editor for the sound event. Any editor that writes RIFF cue points and any tool that edits soundevents_addon.vsndevts will also do.

1. Set up loop marks

Counter-Strike 2 uses RIFF Cue Markers stored directly within .wav files to determine loop start and loop end boundaries.

To add the marks, use the Audio Editor.

1. Double-click the source .wav or .mp3 file in Audio Explorer to open it in the Audio Editor.
2. Listen to the track and find the loop start and loop end points.
3. Press M at the loop start and again at the loop end to place the two markers.
4. Marker 1 and Marker 2 now define the loop region.
5. Press Ctrl+S to save the file as WAV. The two cue points are written into the WAV header.

2. Create the sound event

1. Open the addon's soundevents/soundevents_addon.vsndevts file.

2. Create a new event and name it (for example, radio.music_loop_01).

3. Set the property type = csgo_mega (or csgo_music).

4. In vsnd_files, add the saved .wav file path.

5. Create a Distance Volume Mapping Curve to configure hearing distance:

   • Near volume: 1.0 (at distance 0–100 units).
   • Far volume: 0.01 (at distance 1500 units).

   

note

Why set min volume to 0.01 instead of 0?

If a looping sound event reaches 0.0 volume, Counter-Strike 2 will unload it from player memory, losing its current playback position. Setting min volume to 0.01 keeps the sound synchronizing across all players even when far away.

3. Place the entity in Hammer

1. In Hammer Editor, create a point_soundevent entity.
2. Set Soundevent Name to the custom event (radio.music_loop_01).
3. Set Start On Spawn to true.
4. Run or compile the map. The radio music starts and loops in Counter-Strike 2.
