How to Adjust Audio Levels
There is no “Audio Mixer” panel in evmux. Volume is set per source, in the place that source lives. Nothing shows dB values — the level indicators are simple bars that move with the sound.
Your own microphone
- Open Settings (the gear in the bottom toolbar) → Audio.
- Input volume is the first control: drag the slider to set how loud you go out, and watch the bar move as you speak — that is your live level.
- The speaker icon at the right of that row mutes you.
The same panel holds the microphone selector, AI noise reduction, echo cancellation and auto gain — and the Mic test, which records a few seconds and plays it back exactly as viewers would hear it. That is the reliable way to check your level before going live.
Another participant, or any feed
Every participant, screen share and media share has a tile in the Fast Access Bar along the bottom of the studio.
- Mute it: click the small sound indicator next to the name on the tile. Muting affects everyone — your viewers and the recording, not just what you hear.
- Set a level instead of muting: open the tile’s three-dots menu (or right-click the tile) and use the Volume slider there. Its tooltip reads “Affecting the Broadcast” — this is the level your audience gets. A second or third camera has its own row (Camera 2 Volume, Camera 3 Volume).
- If Live volume meters are switched on, the tile grows a side strip with a meter and a microphone button, and the mute lives there instead.
- A row shows No audio when that feed carries no audio track at all.
Balancing several people
Have each person speak in turn, watch their tile meter, and raise the quiet ones rather than cutting the loud ones — a raised level with AI noise reduction on is usually cleaner than a lowered one. There is no automatic ducking or normalisation.
Background music
Music volume is set in the Music tab, not in any mixer: the speaker icon beside the playlist sets the level for the whole track list. Start low — music sits under speech.
Sound FX pads
Each pad in the Music tab has its own volume: open the pad’s three-dots menu (or right-click it) and a volume bar appears under it. The same menu replaces the pad’s sound and renames it.
Video clips and media
- A video clip playing on the Dynamic Scene has its own control bar over the scene, with a speaker icon on the right for that clip’s volume.
- A video or audio layer in a Pro scene carries its own volume with the layer.
- A shared browser tab only carries audio if the person sharing ticked the browser’s share tab audio checkbox in the picker — no evmux setting can recover it afterwards; the share has to be started again with that box ticked.
What only YOU hear
Two controls change your monitoring only. Neither one touches the broadcast, the recording, or what a single viewer hears — and both get mistaken for muting the stream.
The speaker icon on the scene preview. Each preview — the editor’s scene and the Live Preview — has a small speaker (ear) icon on its title bar that silences that preview for you. Its tooltip says exactly this: “Affecting only on your end”. If someone says “I muted the preview, is my stream muted?”, the answer is no. And if someone hears nothing in the studio while viewers hear everything, this icon is the first thing to check.
Listen Offstage Feeds, at the left of the Fast Access Bar, decides whether you hear the people who are not currently on the scene. It changes your own monitoring only — viewers and the recording are never affected by it.
Troubleshooting
| Symptom | Where to look |
|---|---|
| “You’re too quiet” | Settings → Audio → Input volume, then Mic test to confirm |
| One guest is much louder | their tile’s three-dots menu → Volume |
| Nobody hears a shared tab | the share was started without share tab audio — reshare |
| You hear an off-screen guest (or don’t) | Listen Offstage Feeds toggle |
| Echo | turn echo cancellation on, or ask whoever is on speakers to use headphones |
| Music drowns speech | Music tab → speaker icon beside the playlist |
