To fade audio as nature clips change in OBS, put the clips in scenes, select Fade under Scene Transitions, and set a duration. OBS’s built-in transition is a scene-level control, not a separate audio-fade timer. A 2020 OBS forum response says audio sources entering or leaving with a scene fade during the transition, with no fade tail afterward; check the behavior in your installed version.
Choose how OBS will play the clips
For deliberate control over when each clip changes, use separate scenes and add each clip as a media source. If you want sequential playlist playback instead, OBS’s VLC Video source supports playlists, looping, and shuffle. VLC must be installed for that source type to appear. OBS documents visibility behavior for VLC Video, but does not establish that every playlist change produces the same audio fade as a scene transition.
Separate scenes for deliberate changes
- Create a scene for each clip or intended clip state. Give scenes clear names so you can select the right one while operating OBS.
- Add the clip to its scene using an appropriate media source. The OBS Media Sources guide lists MP3, AAC, OGG, and WAV among supported audio types.
- Arrange and test the scenes in the order you want them to play. This approach makes the scene change the deliberate transition point.
VLC Video for playlist playback
- Install VLC if it is not already installed.
- Add a VLC Video source and configure its playlist and any loop or shuffle options you need.
- Test how your installed OBS version handles the audio at playlist changes. Do not assume playlist item changes use the same fade behavior as switching between scenes.
OBS’s Media Sources guide describes supported source types and VLC Video options.
Set the scene transition to Fade
- In OBS, arrange the scenes and sources so the outgoing and incoming clips are represented in the scene change you intend to make.
- Find the Scene Transitions section in the OBS window.
- Select Fade. OBS’s overview guide says Fade is available from first launch and that the active transition and its duration can be changed.
- Set the Fade duration to suit the pacing and material of your clips. There is no single ideal duration: a slow change in ambience and a quick change between short clips may call for different timing.
- Switch between the scenes and listen to the change. If the audio does not fade as expected, check whether the audio source is present in one scene and absent from the other, and verify the result in your installed OBS version.
The audio detail comes from an OBS community-forum response dated May 14, 2020, rather than the official transition guide: it describes sources entering or leaving with a scene fading during that transition, without continuing afterward. The standard Fade control does not document an independently timed audio fade.

Check levels and confirm the result before going live
- Watch the Audio Mixer meters during a scene change. Mixer controls set source levels; a level adjustment is not itself a scene transition.
- Use audio filters for their intended signal-processing purpose. OBS documents Gain and Compressor in its Filters Guide; compressor sidechain ducking lowers one source in response to another, such as background audio under a microphone. It is not the core control for fading audio with a scene change. See the Compressor Filter guide.
- Record a short sample and listen back. Check that the transition is audible, clips start when expected, and levels do not clip or jump unexpectedly. OBS’s Audio Mixer Guide recommends recording and listening before a live session.
Troubleshoot a fade that does not sound right
| What you hear | What to check | What to do |
|---|---|---|
| No audio fade when switching scenes | Whether the audio source is present in one scene and absent in the other; whether the expected behavior matches your installed OBS version. | Test with a simple pair of scenes and a short recording. The 2020 forum explanation concerns sources entering or leaving with a scene, not every possible scene or playlist arrangement. |
| The sound stops abruptly after the transition | Whether you expected the fade to continue after the scene transition ends. | The forum response describes no fade tail after the transition. The reviewed documentation does not establish a native, independently timed audio envelope for this workflow. |
| Playlist clips change without the expected fade | Whether you are changing VLC playlist items rather than switching scenes. | Test the playlist behavior in your installed version. For a predictable scene-change point, use separate scenes and the Fade transition. |
| Audio jumps or clips during a change | Audio Mixer meters and source levels. | Adjust the source level as needed, then record and listen back before going live. |
