PUBLIC STREAM TOOL / VERSION 4.1

Your audio.
Your cue.

Let your overlays step in when they have something to say—and fade away when they don’t.

Audio Fade links an OBS audio input to the visual sources you choose. Each link listens independently, with its own threshold and silence timer.

THREE WAYS DRIFTER USES IT

A cue for anything in your scene.

These are starting points. Link any OBS audio input to your chosen webcam, image, text, browser source, or other scene item.

Give the gameplay room

Speak and your camera appears. During cutscenes or quiet concentration, it fades away after your chosen silence delay.

Your microphoneYour webcam

Let your friends take the stage

Show your friends’ images while their Discord audio is active; hide them when the conversation goes quiet. A combined Discord capture reacts to anyone on that capture.

Keep the music overlay relevant

Keep an existing now-playing source visible while music is audible, then hide it when the music stops. Audio Fade controls visibility; your music tool supplies the track information.

DRIFTER’S CURRENT SETUP

Three inputs. Three independent jobs.

Audio input	Visual targets	Threshold	Silence	Activation
Microphone	Webcam in the stream scene	−35 dB	6 seconds	450 ms
Discord	Reactive images in the stream scene	−35 dB	3 seconds	450 ms
Music / browser input	Now-playing text in Stream, Starting, BRB, End Stream, and Chatting	−50 dB	1 second	120 ms

Each input controls only its assigned visuals. One input can control sources across several scenes. These settings are examples from Drifter’s dock; tune them to your own audio levels.

FROM THE STREAMING DESK

The dock in use.

Audio Fade dock with independent microphone, Discord, and music links active — All three links in compact mode

Camera link listening only to MIC with a six-second silence delay — Microphone → webcam

Reactive image link listening only to Discord with a three-second silence delay — Discord → reactive images

Music input linked to now-playing text across five OBS scenes — Music → now-playing text

Set the rhythm.

Choose the volume that triggers a source, how long sound must last before it appears, and how long silence lasts before it hides.

Independent linksYour mic controls its targets. Discord and music control theirs, at the same time.
Talking or silent visualsShow a source while audio is active, or use the opposite behavior for an idle image.
A small dock, with room to growCompact mode, per-link toggles, local settings, and copy/paste backups.

QUICK SETUP

One file. An OBS dock.

Save the HTML somewhere permanent.
Download Audio-Fade.html to your streaming PC. Keep the file in place after adding the dock.
Add it to OBS.
Open the file in your browser and copy its file address. In OBS, go to Docks → Custom Browser Docks. Name it Audio Fade, paste that address, and click Apply.
Connect to local OBS.
In Tools → WebSocket Server Settings, enable the server. Use Show Connect Info to find the port and password, then enter them in the dock’s OBS connection section.
Build your audio → visual links.
Choose one audio input per link, add its visual targets in the appropriate scene, and enable the links. Try −35 dB and 6 seconds of silence for commentary; use a shorter delay for reactive images.
Set your fades.
Right-click each target in OBS Sources. Set Show Transition → Fade and Hide Transition → Fade. Start with 250 ms in and 700 ms out, then adjust to taste.

Before your next stream

This reacts to volume, not speech or speaker identity. Use isolated audio inputs so a mixed desktop bus doesn’t trigger unrelated visuals. Separate guest reactions need separate guest audio inputs.

Keep your always-visible sources outside the links. Settings save locally when dock storage is available; Export rules provides a copy/paste backup. Passwords are not saved. Links stay enabled through scene changes: when an input disappears, its link waits and resumes automatically when audio meter data returns. Disable the links before closing to restore their original visibility.

Version 4.1 has passed simulated selection, persistence, and independent-trigger tests. Test the dock with your OBS setup before relying on it live.
